諸如經封裝與未經封裝之半導體晶片等半導體元件可提供高電壓、高頻率及高效能之應用;該些應用為執行特定功能,所需消耗之功率甚高,然功率愈高則半導體元件生熱愈多。此外,在封裝密度提高及尺寸縮減後,可供散熱之表面積縮小,更導致生熱加劇。Semiconductor components such as packaged and unpackaged semiconductor wafers can provide high voltage, high frequency, and high performance applications; these applications require a very high amount of power to perform a particular function, but the higher the power, the higher the semiconductor component More heat. In addition, after the package density is increased and the size is reduced, the surface area available for heat dissipation is reduced, which further increases heat generation.

半導體元件在高溫操作下易產生效能衰退及使用壽命縮短等問題,甚至可能立即故障。高熱不僅影響晶片效能,亦可能因熱膨脹不匹配而對晶片及其週遭元件產生熱應力作用。因此,必須使晶片迅速有效散熱方能確保其操作之效率與可靠度。一條高導熱性路徑通常係將熱能傳導並發散至一表面積較晶片或晶片所在之晶粒座更大之區域。Semiconductor components are prone to performance degradation and shortened service life under high temperature operation, and may even malfunction immediately. High heat not only affects wafer performance, but may also cause thermal stress on the wafer and its surrounding components due to thermal expansion mismatch. Therefore, the wafer must be quickly and efficiently dissipated to ensure the efficiency and reliability of its operation. A high thermal conductivity path typically conducts and dissipates thermal energy to a region of greater surface area than the die pad in which the wafer or wafer is located.

發光二極體(LED)近來已普遍成為白熾光源、螢光光源與鹵素光源之替代光源。LED可為醫療、軍事、招牌、訊號、航空、航海、車輛、可攜式設備、商用與住家照明等應用領域提供高能源效率及低成本之長時間照明。例如,LED可為燈具、手電筒、車頭燈、探照燈、交通號誌燈及顯示器等設備提供光源。Light-emitting diodes (LEDs) have recently become an alternative source of incandescent, fluorescent, and halogen sources. LEDs provide high energy efficiency and low cost long-term illumination for medical, military, signage, signal, aerospace, marine, vehicle, portable, commercial and residential lighting applications. For example, LEDs can provide light sources for fixtures, flashlights, headlights, searchlights, traffic lights, and displays.

LED中之高功率晶片在提供高亮度輸出之同時亦產生大量熱能。然而,在高溫操作下,LED會發生色偏、亮度降低、使用壽命縮短及立即故障等問題。此外,LED在散熱方面有其限制,進而影響其光輸出與可靠度。因此,LED格外突顯市場對於具有良好散熱效果之高功率晶片之需求。The high power chips in the LEDs also produce a large amount of thermal energy while providing high brightness output. However, under high temperature operation, LEDs may suffer from color shift, brightness reduction, shortened service life, and immediate failure. In addition, LEDs have limitations in terms of heat dissipation, which in turn affects their light output and reliability. Therefore, LEDs highlight the market's need for high-power chips with good heat dissipation.

LED封裝體通常包含一LED晶片、一基座、電接點及一熱接點。所述基座係熱連結至LED晶片並用以支撐該LED晶片。電接點則電性連結至LED晶片之陽極與陰極。熱接點經由該基座熱連結至LED晶片,其下方載具可充分散熱以預防LED晶片過熱。The LED package typically includes an LED chip, a pedestal, electrical contacts, and a thermal contact. The pedestal is thermally coupled to the LED wafer and used to support the LED wafer. The electrical contacts are electrically connected to the anode and cathode of the LED chip. The thermal contacts are thermally coupled to the LED wafer via the pedestal, and the underlying carrier is sufficiently thermally dissipated to prevent overheating of the LED wafer.

業界積極以各種設計及製造技術投入高功率晶片封裝體與導熱板之研發,以期在此極度成本競爭之環境中滿足效能需求。The industry is actively investing in the development of high-power chip packages and thermal boards with various design and manufacturing technologies in order to meet performance requirements in this extremely cost-competitive environment.

塑膠球柵陣列(PBGA)封裝係將一晶片與一層壓基板包裹於一塑膠外殼中,然後再以錫球黏附於一印刷電路板(PCB)之上。所述層壓基板包含一通常由玻璃纖維構成之介電層。晶片產生之熱能可經由塑膠及介電層傳至錫球,進而傳至印刷電路板。然而,由於塑膠與介電層之導熱性低,PBGA之散熱效果不佳。A plastic ball grid array (PBGA) package encloses a wafer and a laminate substrate in a plastic case and then adheres to a printed circuit board (PCB) with solder balls. The laminate substrate comprises a dielectric layer typically composed of glass fibers. The heat generated by the wafer can be transferred to the solder ball via the plastic and dielectric layers and transferred to the printed circuit board. However, due to the low thermal conductivity of the plastic and dielectric layers, the PBGA has a poor heat dissipation effect.

方形扁平無引腳(QFN)封裝係將晶片設置在一焊接於印刷電路板之銅質晶粒座上。晶片產生之熱能可經由晶粒座傳至印刷電路板。然而,由於其導線架中介層之路由能力有限,使得QFN封裝無法適用於高輸入/輸出(I/O)晶片或被動元件。A quad flat no-lead (QFN) package places the wafer on a copper die pad that is soldered to a printed circuit board. The thermal energy generated by the wafer can be transferred to the printed circuit board via the die pad. However, due to the limited routing capabilities of its leadframe interposer, QFN packages are not suitable for high input/output (I/O) chips or passive components.

導熱板為半導體元件提供電性路由、熱管理與機械性支撐等功能。導熱板通常包含一用於訊號路由之基板、一提供熱去除功能之散熱座或散熱裝置、一可供電性連結至半導體元件之焊墊,以及一可供電性連結至下一層組體之端子。該基板可為一具有單層或多層路由電路系統及一或多層介電層之層壓結構。該散熱座可為一金屬基座、金屬塊或埋設金屬層。The heat conducting plate provides electrical routing, thermal management, and mechanical support for the semiconductor components. The heat conducting board usually comprises a substrate for signal routing, a heat sink or heat sink for providing heat removal function, a solder pad electrically connectable to the semiconductor component, and a terminal electrically connectable to the next layer assembly. The substrate can be a laminate structure having a single or multi-layer routing circuitry and one or more dielectric layers. The heat sink can be a metal base, a metal block or a buried metal layer.

導熱板接合下一層組體。例如,下一層組體可為一具有印刷電路板及散熱裝置之燈座。在此範例中,一LED封裝體係安設於導熱板上,該導熱板則安設於散熱裝置上,導熱板/散熱裝置次組體與印刷電路板又安設於燈座中。此外,導熱板經由導線電性連結至該印刷電路板。該基板將電訊號自該印刷電路板導向LED封裝體,而該散熱座則將LED封裝體之熱能發散並傳遞至該散熱裝置。因此,該導熱板可為LED晶片提供一重要之熱路徑。The heat conducting plate engages the next layer of the body. For example, the next layer of the body can be a lamp holder having a printed circuit board and a heat sink. In this example, an LED package system is disposed on the heat conducting plate, and the heat conducting plate is disposed on the heat dissipating device, and the heat conducting plate/heat dissipating device sub-group and the printed circuit board are further disposed in the lamp holder. In addition, the heat conducting plate is electrically connected to the printed circuit board via wires. The substrate directs the electrical signal from the printed circuit board to the LED package, and the heat sink scatters and transfers the thermal energy of the LED package to the heat sink. Therefore, the heat conducting plate can provide an important thermal path for the LED wafer.

授予Juskey等人之第6,507,102號美國專利揭示一種組體,其中一由玻璃纖維與固化之熱固性樹脂所構成之複合基板包含一中央開口。一具有類似前述中央開口正方或長方形狀之散熱塊係黏附於該中央開口側壁因而與該基板結合。上、下導電層分別黏附於該基板之頂部及底部,並透過貫穿該基板之電鍍導孔互為電性連結。一晶片係設置於散熱塊上並打線接合至上導電層,一封裝材料係模設成形於晶片上,而下導電層則設有錫球。U.S. Patent No. 6,507,102 to the disclosure of U.S. Pat. A heat dissipating block having a square or rectangular shape similar to the central opening is adhered to the central opening side wall and thus joined to the substrate. The upper and lower conductive layers are respectively adhered to the top and bottom of the substrate, and are electrically connected to each other through the plating vias penetrating the substrate. A wafer is disposed on the heat dissipation block and wire bonded to the upper conductive layer, a package material is molded on the wafer, and a lower conductive layer is provided with a solder ball.

製造時,該基板原為一置於下導電層上之乙階(B-stage)樹脂膠片。散熱塊係插設於中央開口,因而位於下導電層上,並與該基板以一間隙相隔。上導電層則設於該基板上。上、下導電層經加熱及彼此壓合後,使樹脂熔化並流入前述間隙中固化。上、下導電層形成圖案,因而在該基板上形成電路佈線,並使樹脂溢料顯露於散熱塊上。然後去除樹脂溢料,使散熱塊露出。最後再將晶片安置於散熱塊上並進行打線接合與封裝。When manufactured, the substrate was originally a B-stage resin film placed on the lower conductive layer. The heat dissipating block is inserted in the central opening so as to be located on the lower conductive layer and separated from the substrate by a gap. The upper conductive layer is disposed on the substrate. After the upper and lower conductive layers are heated and pressed together, the resin is melted and flows into the gap to be solidified. The upper and lower conductive layers are patterned, thereby forming circuit wiring on the substrate and exposing the resin flash to the heat sink. The resin flash is then removed to expose the heat sink. Finally, the wafer is placed on the heat sink block and bonded and packaged.

因此,晶片產生之熱能可經由散熱塊傳至印刷電路板。然而在量產時,以手工方式將散熱塊放置於中央開口內之作業極為費工,且成本高昂。再者,由於側向之安裝容差小,散熱塊不易精確定位於中央開口中,導致基板與散熱塊之間易出現間隙以及打線不均之情形。如此一來,該基板僅部分黏附於散熱塊,無法自散熱塊獲得足夠支撐力,且容易脫層。此外,用於去除部分導電層以顯露樹脂溢料之化學蝕刻液亦將去除部分未被樹脂溢料覆蓋之散熱塊,使散熱塊不平且不易結合,最終導致組體之良率降偏低、可靠度不足且成本過高。Therefore, the thermal energy generated by the wafer can be transferred to the printed circuit board via the heat slug. However, in mass production, the manual placement of the heat sink in the central opening is labor intensive and costly. Moreover, since the mounting tolerance of the lateral direction is small, the heat dissipating block is not easily positioned in the central opening, which may cause a gap between the substrate and the heat dissipating block and uneven wiring. As a result, the substrate is only partially adhered to the heat dissipation block, and sufficient support force cannot be obtained from the heat dissipation block, and the layer is easily delaminated. In addition, the chemical etching solution for removing part of the conductive layer to expose the resin flash will also remove some of the heat-dissipating block which is not covered by the resin flash, so that the heat-dissipating block is not flat and difficult to combine, and finally the yield of the group is lowered, Insufficient reliability and high cost.

授予Ding等人之第6,528,882號美國專利揭露一種高散熱球柵陣列封裝體,其基板包含一金屬芯層,而晶片則安置於金屬芯層頂面之晶粒座區域。一絕緣層係形成於金屬芯層之底面。盲孔貫穿絕緣層直通金屬芯層,且孔內填有散熱錫球,另在該基板上設有與散熱錫球相對應之錫球。晶片產生之熱能可經由金屬芯層流向散熱錫球,再流向印刷電路板。然而,夾設於金屬芯層與印刷電路板間之絕緣層卻對流向印刷電路板之熱流造成限制。US Patent No. 6,528,882 to Ding et al. discloses a high heat dissipation ball grid array package having a substrate comprising a metal core layer and a wafer disposed in a die pad region on the top surface of the metal core layer. An insulating layer is formed on the bottom surface of the metal core layer. The blind hole penetrates the insulating layer through the metal core layer, and the hole is filled with the heat-dissipating solder ball, and the solder ball corresponding to the heat-dissipating solder ball is further disposed on the substrate. The thermal energy generated by the wafer can flow through the metal core to the heat sink balls and then to the printed circuit board. However, the insulating layer sandwiched between the metal core layer and the printed circuit board limits the heat flow to the printed circuit board.

授予Lee等人之第6,670,219號美國專利教示一種凹槽向下球柵陣列(CDBGA)封裝體,其中一具有中央開口之接地板係設置於一散熱座上以構成一散熱基板。一具有中央開口之基板透過一具有中央開口之黏著層設置於該接地板上。一晶片係安裝於該散熱座上由接地板中央開口所形成之一凹槽內,且該基板上設有錫球。然而,由於錫球係位於基板上,散熱座並無法接觸印刷電路板,導致該散熱座之散熱作用僅限熱對流而非熱傳導,因而大幅限縮其散熱效果。U.S. Patent No. 6,670,219 to Lee et al., the disclosure of which is incorporated herein by reference. A substrate having a central opening is disposed on the ground plate through an adhesive layer having a central opening. A chip is mounted on the heat sink in a recess formed by the central opening of the ground plate, and the substrate is provided with a solder ball. However, since the solder ball is located on the substrate, the heat sink cannot contact the printed circuit board, and the heat dissipation effect of the heat sink is limited to heat convection instead of heat conduction, thereby greatly reducing the heat dissipation effect.

授予Woodall等人之第7,038,311號美國專利提供一種高散熱BGA封裝體,其散熱裝置為倒T形且包含一柱部與一寬基底。一設有窗型開口之基板係安置於寬基底上,一黏著層則將柱部與寬基底黏附於該基板。一晶片係安置於柱部上並打線接合至該基板,一封裝材料係模製成形於晶片上,該基板上則設有錫球。柱部延伸穿過該窗型開口,並由寬基底支撐該基板,至於錫球則位於寬基底與基板周緣之間。晶片產生之熱能可經由柱部傳至寬基底,再傳至印刷電路板。然而,由於寬基底上必須留有容納錫球之空間,寬基底僅在對應於中央窗口與最內部錫球之間的位置突伸於該基板下方。如此一來,該基板在製造過程中便不平衡,且容易晃動及彎曲,進而導致晶片之安裝、打線接合以及封裝材料之模製成形均十分困難。此外,該寬基底可能因封裝材料之模製成形而彎折,且一旦錫球崩塌,便可能使該封裝體無法焊接至下一層組體。是以,此封裝體之良率偏低、可靠度不足且成本過高。U.S. Patent No. 7,038,311 to Woodall et al. provides a high-heat-dissipating BGA package having a heat sink that is inverted T-shaped and includes a post portion and a wide base. A substrate having a window-shaped opening is disposed on the wide substrate, and an adhesive layer adheres the pillar portion and the wide substrate to the substrate. A wafer system is disposed on the pillar portion and wire bonded to the substrate, and a packaging material is molded on the wafer, and the substrate is provided with a solder ball. A post extends through the window opening and supports the substrate by a wide substrate, with the solder ball being between the wide substrate and the periphery of the substrate. The thermal energy generated by the wafer can be transferred to the wide substrate via the post and then to the printed circuit board. However, since a space for accommodating the solder balls must be left on the wide substrate, the wide substrate protrudes below the substrate only at a position corresponding to the central window and the innermost tin ball. As a result, the substrate is unbalanced during the manufacturing process, and is easily shaken and bent, thereby causing difficulty in mounting, wire bonding, and molding of the package material. In addition, the wide substrate may be bent due to the molding of the encapsulating material, and once the solder ball collapses, the package may not be soldered to the next layer. Therefore, the yield of the package is low, the reliability is insufficient, and the cost is too high.

Erchak等人之美國專利申請公開案第2007/0267642號提出一種發光裝置組體,其中一倒T形之基座包含一基板、一突出部及一具有通孔之絕緣層,絕緣層上並設有電接點。一具有通孔與透明上蓋之封裝體係設置於電接點上。一LED晶片係設置於突出部並以打線連接該基板。該突出部係鄰接該基板並延伸穿過絕緣層與封裝體上之通孔,進入封裝體內。絕緣層係設置於該基板上,且絕緣層上設有電接點。封裝體係設置於該等電接點上並與絕緣層保持間距。該晶片產生之熱能可經由突出部傳至該基板,進而到達一散熱裝置。然而,該等電接點不易設置於絕緣層上,難以與下一層組體電性連結,且無法提供多層路由。U.S. Patent Application Publication No. 2007/0267642 to Erchak et al., which is incorporated herein by reference in its entirety, the entire entire entire entire entire entire entire entire entire entire entire entire entire contents There are electrical contacts. A packaging system having a through hole and a transparent upper cover is disposed on the electrical contact. An LED chip is disposed on the protruding portion and connected to the substrate by wire bonding. The protrusion is adjacent to the substrate and extends through the insulating layer and the through hole on the package to enter the package. An insulating layer is disposed on the substrate, and an electrical contact is disposed on the insulating layer. The packaging system is disposed on the electrical contacts and spaced apart from the insulating layer. The heat generated by the wafer can be transferred to the substrate via the protrusions to reach a heat sink. However, the electrical contacts are not easily disposed on the insulating layer, and are difficult to electrically connect with the next layer of the assembly, and cannot provide multilayer routing.

習知封裝體與導熱板具有重大缺點。舉例而言,諸如環氧樹脂等低導熱性之電絕緣材料對散熱效果造成限制,然而,以陶瓷或碳化矽填充之環氧樹脂等具有較高導熱性之電絕緣材料則具有黏著性低且量產成本過高之缺點。該電絕緣材料可能在製作過程中或在操作初期即因受熱而脫層。該基板若為單層電路系統則路由能力有限,但若該基板為多層電路系統,則其過厚之介電層將降低散熱效果。此外,前案技術尚有散熱座效能不足、體積過大或不易熱連結至下一層組體等問題。前案技術之製造工序亦不適於低成本之量產作業。Conventional packages and thermally conductive plates have major drawbacks. For example, an electrically insulating material having a low thermal conductivity such as an epoxy resin limits the heat dissipation effect, however, an electrically insulating material having a high thermal conductivity such as an epoxy resin filled with ceramic or tantalum carbide has low adhesion. The disadvantage of high production cost. The electrically insulating material may be delaminated by heat during the manufacturing process or at the beginning of the operation. If the substrate is a single-layer circuit system, the routing capability is limited. However, if the substrate is a multi-layer circuit system, the excessively thick dielectric layer will reduce the heat dissipation effect. In addition, the previous case technology still has problems such as insufficient heat sink performance, excessive volume or difficulty in thermally connecting to the next layer. The manufacturing process of the prior art is also not suitable for low-cost mass production operations.

圖1B為一剖視圖,顯示金屬板10上形成有一圖案化之蝕刻阻層16與一全面覆蓋之蝕刻阻層18。圖示之圖案化之蝕刻阻層16與全面覆蓋之蝕刻阻層18係沉積於金屬板10上之光阻層,其製作方式係利用壓模技術以熱滾輪同時將光阻層分別壓合於表面12及14。濕性旋塗法及淋幕塗佈法亦為適用之光阻形成技術。將一光罩(圖未示)靠合於光阻層,然後依照習知技術,令光線選擇性通過光罩,使受光之光阻部分變為不可溶解;之後再以顯影液去除未受光且仍可溶解之光阻部分,使光阻層形成圖案。因此,圖案化之蝕刻阻層16具有一可選擇性曝露表面12之圖案,而全面覆蓋之蝕刻阻層18則無圖案且覆蓋表面14。1B is a cross-sectional view showing a patterned etch stop layer 16 and a etch stop layer 18 overlying the metal plate 10. The patterned etch stop layer 16 and the over-etched etch stop layer 18 are deposited on the metal plate 10 in a photoresist layer. The photoresist layer is used to simultaneously press the photoresist layer with a hot roller. Surfaces 12 and 14. Wet spin coating and curtain coating are also suitable photoresist forming techniques. A reticle (not shown) is placed on the photoresist layer, and then light is selectively passed through the reticle to make the light-receiving portion of the light-receivable portion insoluble according to conventional techniques; The photoresist portion, which is still soluble, forms a pattern of the photoresist layer. Thus, the patterned etch stop layer 16 has a pattern of selectively exposed surface 12, while the overlying etch stop layer 18 is unpatterned and covers the surface 14.

圖1C為一剖視圖,顯示金屬板10形成有掘入但未穿透金屬板10之凹槽20。凹槽20係以蝕刻金屬板10之方式形成,以使金屬板10形成由圖案化之蝕刻阻層16所定義之圖案。圖示之蝕刻方式為正面濕式化學蝕刻。例如,可將結構體反轉,使圖案化之蝕刻阻層16朝下,而全面覆蓋之蝕刻阻層18朝上,然後利用一面向圖案化蝕刻阻層16之底部噴嘴(圖未示)將化學蝕刻液朝上噴灑於金屬板10及圖案化之蝕刻阻層16,在此同時,一面向全面覆蓋之蝕刻 阻層18之頂部噴嘴(圖未示)則不予啟動,如此一來便可借助重力去除蝕刻之副產物。或者,利用全面覆蓋之蝕刻阻層18提供背面保護,亦可將結構體浸入化學蝕刻液中以形成凹槽20。所述化學蝕刻液對銅具有高度針對性,且可刻入金屬板10達300微米。因此,凹槽20自表面12延伸進入但未穿透金屬板10,與表面14距離30微米,深度則為300微米。化學蝕刻液亦對圖案化之蝕刻阻層16下方之金屬板10造成側向蝕入。適用之化學蝕刻液可為含鹼氨之溶液或硝酸與鹽酸之稀釋混合物。換言之,所述化學蝕刻液可為酸性或鹼性。足以形成凹槽20而不致使金屬板10過度曝露於化學蝕刻液之理想蝕刻時間可由試誤法決定。1C is a cross-sectional view showing the metal plate 10 formed with a recess 20 which is dug but does not penetrate the metal plate 10. The recess 20 is formed by etching the metal plate 10 such that the metal plate 10 forms a pattern defined by the patterned etch stop layer 16. The etching method shown is a front wet chemical etching. For example, the structure can be reversed such that the patterned etch stop layer 16 faces downward, while the overlying etch stop layer 18 faces upward, and then a bottom nozzle (not shown) that faces the patterned etch stop layer 16 The chemical etching solution is sprayed upward on the metal plate 10 and the patterned etching resist layer 16, while at the same time, an etching is provided for the full coverage. The top nozzle (not shown) of the resist layer 18 is not activated, so that the by-product of the etching can be removed by gravity. Alternatively, the backside protection can be provided by a fully covered etch stop layer 18, and the structure can also be immersed in a chemical etchant to form the recess 20. The chemical etchant is highly targeted to copper and can be engraved into the metal sheet 10 up to 300 microns. Thus, the recess 20 extends from the surface 12 but does not penetrate the metal sheet 10, 30 microns from the surface 14, and 300 microns deep. The chemical etchant also causes lateral etch in the metal plate 10 beneath the patterned etch stop layer 16. Suitable chemical etching solutions can be alkaline ammonia-containing solutions or diluted mixtures of nitric acid and hydrochloric acid. In other words, the chemical etching solution can be acidic or alkaline. The ideal etching time sufficient to form the recess 20 without causing the metal plate 10 to be excessively exposed to the chemical etchant can be determined by trial and error.

圖1D、圖1E及圖1F分別為去除圖案化之蝕刻阻層16及全面覆蓋之蝕刻阻層18後之金屬板10之剖視圖、俯視圖及仰視圖,其中案化之蝕刻阻層16與全面覆蓋之蝕刻阻層18已經溶劑處理去除。例如,所用溶劑可為pH為14之強鹼性氫氧化鉀溶液。1D, FIG. 1E, and FIG. 1F are respectively a cross-sectional view, a top view, and a bottom view of the metal plate 10 after the patterned etch stop layer 16 and the etch stop layer 18 are completely covered, wherein the etched resist layer 16 and the full cover are respectively covered. The etch stop layer 18 has been removed by solvent treatment. For example, the solvent used may be a strong alkaline potassium hydroxide solution having a pH of 14.

蝕刻後之金屬板10因此包含導熱凸柱22、訊號凸柱24及基座26。The etched metal plate 10 thus includes a thermally conductive stud 22, a signal stud 24, and a pedestal 26.

導熱凸柱22為金屬板10受圖案化之蝕刻阻層16保護之一第一未受蝕刻部分。導熱凸柱22係鄰接基座26,與基座26形成一體,且突伸於基座26上方,並由凹槽20從側向包圍。導熱凸柱22高300微米(等於凹槽20之深度),其頂面(表面12之圓形部分)之直徑為1000微米,而底部(鄰接基座26之圓形部分)之直徑則為1100微米。因此,導熱 凸柱22呈平頂錐柱形(類似一平截頭體),其側壁漸縮,直徑則自基座26處朝其平坦圓形頂面向上遞減。該漸縮側壁係因化學蝕刻液側向蝕入圖案化之蝕刻阻層16下方而形成。該頂面與該底部之圓周同心(如圖1E所示)。The thermally conductive studs 22 are one of the first unetched portions of the metal plate 10 protected by the patterned etch stop layer 16. The thermally conductive stud 22 is adjacent to the base 26 and is integral with the base 26 and projects above the base 26 and is laterally surrounded by the recess 20. The thermally conductive stud 22 is 300 microns high (equal to the depth of the groove 20), the top surface (the circular portion of the surface 12) having a diameter of 1000 microns, and the bottom portion (the circular portion adjacent the pedestal 26) having a diameter of 1100. Micron. Therefore, heat conduction The stud 22 has a flat-topped tapered cylindrical shape (like a frustum) with its side walls tapered and the diameter decreasing from the base 26 toward its flat circular top surface. The tapered sidewalls are formed by lateral etching of the chemical etchant into the patterned etch stop layer 16. The top surface is concentric with the circumference of the bottom (as shown in Figure 1E).

訊號凸柱24為金屬板10受圖案化之蝕刻阻層16保護之一第二未受蝕刻部分。訊號凸柱24係鄰接基座26,與基座26形成一體,且突伸於基座26上方,並由凹槽20從側向包圍。訊號凸柱24高300微米(等於凹槽20之深度),其頂面(表面12之圓形部分)之直徑為300微米,而底部(鄰接基座26之圓形部分)之直徑則為400微米。因此,訊號凸柱24呈平頂錐柱形(類似一平截頭體),其側壁漸縮,直徑則自基座26處朝其平坦圓形頂面向上遞減。該漸縮側壁係因化學蝕刻液側向蝕入圖案化之蝕刻阻層16下方而形成。該頂面與該底部之圓周同心(如圖1E所示)。The signal studs 24 are one of the second unetched portions of the metal plate 10 protected by the patterned etch stop layer 16. The signal stud 24 is adjacent to the base 26 and is integral with the base 26 and projects above the base 26 and is laterally surrounded by the recess 20. The signal stud 24 is 300 microns high (equal to the depth of the groove 20), the top surface (the circular portion of the surface 12) has a diameter of 300 microns, and the bottom portion (the circular portion adjacent the pedestal 26) has a diameter of 400. Micron. Thus, the signal studs 24 are in the form of a flat-topped conical cylinder (like a frustum) with the side walls tapered and the diameter decreasing from the base 26 toward its flat circular top surface. The tapered sidewalls are formed by lateral etching of the chemical etchant into the patterned etch stop layer 16. The top surface is concentric with the circumference of the bottom (as shown in Figure 1E).

基座26為金屬板10在導熱凸柱22與訊號凸柱24下方之一未受蝕刻部分,並自導熱凸柱22、訊號凸柱24沿一側向平面(如左、右等側面方向)側向延伸,厚度為30微米(即330微米減去300微米)。The pedestal 26 is an unetched portion of the metal plate 10 below the heat conducting stud 22 and the signal stud 24, and is laterally oriented from the heat conducting stud 22 and the signal stud 24 (such as the left and right sides). Laterally extending, the thickness is 30 microns (ie 330 microns minus 300 microns).

導熱凸柱22、訊號凸柱24與基座26可經處理以加強與環氧樹脂及焊料之結合度。例如,導熱凸柱22、訊號凸柱24與基座26可經化學氧化或微蝕刻以產生較粗糙之表面。The thermally conductive studs 22, signal posts 24 and pedestal 26 can be treated to enhance bonding to epoxy and solder. For example, the thermally conductive studs 22, the signal studs 24, and the pedestal 26 can be chemically oxidized or microetched to create a rougher surface.

導熱凸柱22、訊號凸柱24與基座26在圖式中為透過削減法形成之單一金屬(銅)體。此外,亦可利用一接觸件沖 壓金屬板10,其中該接觸件具有可定義導熱凸柱22之第一凹槽或孔洞以及可定義訊號凸柱24之第二凹槽或孔洞,俾使導熱凸柱22、訊號凸柱24與基座26成為沖壓成型之單一金屬體。或者,可利用增添法形成導熱凸柱22、訊號凸柱24,其作法係透過電鍍、化學氣相沉積(CVD)、物理氣相沉積(PVD)等技術,將導熱凸柱22、訊號凸柱24沉積於基座26上。例如,可於銅質基座26上電鍍焊料導熱凸柱22及焊料訊號凸柱24;在此情況下,導熱凸柱22與基座26係以冶金介面相接,彼此鄰接但並非一體成形,訊號凸柱24與基座26係以冶金介面相接,彼此鄰接但並非一體成形。或者,可利用半增添法形成導熱凸柱22、訊號凸柱24,例如可於導熱凸柱22、訊號凸柱24其蝕刻形成之下部上方分別沉積導熱凸柱22、訊號凸柱24之上部。此外,導熱凸柱22、訊號凸柱24與基座26亦可同時以半增添法形成,例如可在導熱凸柱22、訊號凸柱24與基座26其蝕刻形成之下部上方分別沉積導熱凸柱22、訊號凸柱24與基座26之同形上部。導熱凸柱22、訊號凸柱24亦可燒結於基座26。The thermally conductive studs 22, the signal studs 24 and the pedestal 26 are in the form of a single metal (copper) body formed by a reduction process. In addition, you can also use a contact to punch Pressing the metal plate 10, wherein the contact member has a first groove or hole defining a heat conducting stud 22 and a second groove or hole defining the signal stud 24, so that the heat conducting stud 22 and the signal stud 24 are The susceptor 26 is a single metal body that is stamped and formed. Alternatively, the thermally conductive studs 22 and the signal studs 24 may be formed by an additive method, and the thermally conductive studs 22 and the signal studs may be passed through electroplating, chemical vapor deposition (CVD), physical vapor deposition (PVD), or the like. 24 is deposited on the susceptor 26. For example, the solder thermally conductive studs 22 and the solder signal studs 24 can be plated on the copper pedestal 26; in this case, the thermally conductive studs 22 and the pedestal 26 are joined by a metallurgical interface, adjacent to each other but not integrally formed. The signal studs 24 and the pedestal 26 are joined by a metallurgical interface, adjacent to each other but not integrally formed. Alternatively, the thermally conductive studs 22 and the signal studs 24 can be formed by a semi-additive method. For example, the thermally conductive studs 22 and the upper portions of the signal studs 24 can be respectively deposited on the lower portions of the thermally conductive studs 22 and the signal studs 24. In addition, the heat conducting studs 22, the signal studs 24 and the pedestal 26 can also be formed by a semi-additive method. For example, thermal conductive bumps can be respectively deposited on the lower portions of the thermally conductive studs 22, the signal studs 24 and the pedestals 26. The column 22, the signal stud 24 and the base 26 have the same upper portion. The thermally conductive studs 22 and the signal studs 24 can also be sintered to the pedestal 26.

圖2A為黏著層28之剖視圖,其中黏著層28為乙階(B-stage)未固化環氧樹脂之膠片,其為一未經固化且無圖案之片體,厚180微米。2A is a cross-sectional view of the adhesive layer 28 in which the adhesive layer 28 is a B-stage uncured epoxy film which is an uncured and unpatterned sheet having a thickness of 180 microns.

黏著層28可為多種有機或無機電性絕緣體製成之各種介電膜或膠片。例如,黏著層28起初可為一膠片,其中樹脂型態之熱固性環氧樹脂浸入一加強材料後部分固化至中期。所述環氧樹脂可為FR-4,但亦可使用諸如多官能與雙馬來醯亞胺-三氮雜苯(BT)樹脂等其他環氧樹脂。在特定應用中,氰酸酯、聚醯亞胺及聚四氟乙烯(PTFE)亦為可用之環氧樹脂。所述加強材料可為電子級玻璃,亦可為其他加強材料,如高強度玻璃、低誘電率玻璃、石英、克維拉纖維(kevlar aramid)及紙等。所述加強材料也可為織物、不織布或無方向性微纖維。可將諸如矽(研粉熔融石英)等填充物加入膠片中以提升導熱性、熱衝擊阻抗力與熱膨脹匹配性。可利用市售預浸漬體,如美國威斯康辛州奧克萊W.L.Gore & Associates之SPEEDBOARD C膠片即為一例。Adhesive layer 28 can be a variety of dielectric films or films made from a variety of organic or inorganic electrical insulators. For example, the adhesive layer 28 may initially be a film in which the resin-type thermosetting epoxy resin is partially cured to a medium stage after being immersed in a reinforcing material. The epoxy resin may be FR-4, but other epoxy resins such as polyfunctional and bismaleimide-triazabenzene (BT) resins may also be used. Cyanate esters, polyimine and polytetrafluoroethylene (PTFE) are also useful epoxy resins in certain applications. The reinforcing material may be an electronic grade glass, or may be other reinforcing materials such as high-strength glass, low-induced glass, quartz, kevlar aramid, and paper. The reinforcing material may also be a woven fabric, a non-woven fabric or a non-directional microfiber. Fillers such as enamel (melt fused silica) can be added to the film to improve thermal conductivity, thermal shock resistance and thermal expansion matching. Commercially available prepregs can be utilized, such as the SPEEDBOARD C film from W. L. Gore & Associates of Oakley, Wisconsin, USA.

圖2B、圖2C及圖2D分別為具有開口30、32之黏著層28的剖視圖、俯視圖及仰視圖。開口30貫穿黏著層28且直徑為1150微米。開口32貫穿黏著層28且直徑為450微米。開口30、32係以機械方式鑽透該膠片而形成,但亦可以其他技術製作,如沖製及沖壓等。2B, 2C, and 2D are cross-sectional, top, and bottom views, respectively, of the adhesive layer 28 having openings 30,32. The opening 30 extends through the adhesive layer 28 and has a diameter of 1150 microns. Opening 32 extends through adhesive layer 28 and has a diameter of 450 microns. The openings 30, 32 are formed by mechanically drilling through the film, but may be fabricated by other techniques, such as stamping and stamping.

圖3A及圖3B為剖視圖,說明本發明之一實施例中一種製作基板34之方法,而圖3C及圖3D則分別為根據圖3B繪製之俯視圖及仰視圖。3A and 3B are cross-sectional views illustrating a method of fabricating a substrate 34 in accordance with an embodiment of the present invention, and FIGS. 3C and 3D are a plan view and a bottom view, respectively, according to FIG. 3B.

圖3A係基板34之剖視圖。基板34包含導電層36與介電層38。導電層36為電性導體,其接觸介電層38且延伸於介電層38上方。介電層38則為電性絕緣體。例如, 導電層36係一無圖案且厚度為30微米之銅板,而介電層38則為厚度為150微米之環氧樹脂。3A is a cross-sectional view of the substrate 34. The substrate 34 includes a conductive layer 36 and a dielectric layer 38. Conductive layer 36 is an electrical conductor that contacts dielectric layer 38 and extends over dielectric layer 38. Dielectric layer 38 is an electrical insulator. E.g, The conductive layer 36 is a copper plate having a pattern of 30 micrometers in thickness, and the dielectric layer 38 is an epoxy resin having a thickness of 150 micrometers.

圖3B、圖3C及圖3D分別為具有通孔40、42之基板34之剖視圖、俯視圖及仰視圖。通孔40貫穿基板34且直徑為1150微米。通孔42貫穿基板34且直徑為450微米。通孔40、42係以機械方式鑽透導電層36與介電層38而形成,但亦可以其他技術製作,如沖製及沖壓等。較佳者,開口30與通孔40具有相同直徑,且係以相同之鑽頭在同一鑽台上透過相同方式形成;而開口32與通孔42亦具有相同直徑,且係以相同之鑽頭在同一鑽台上透過相同方式形成。3B, 3C, and 3D are a cross-sectional view, a plan view, and a bottom view, respectively, of the substrate 34 having the through holes 40, 42. The through hole 40 penetrates the substrate 34 and has a diameter of 1150 μm. The through hole 42 penetrates the substrate 34 and has a diameter of 450 μm. The through holes 40, 42 are formed by mechanically drilling through the conductive layer 36 and the dielectric layer 38, but may be fabricated by other techniques such as punching and stamping. Preferably, the opening 30 has the same diameter as the through hole 40 and is formed in the same manner on the same drill floor by the same drill bit; and the opening 32 and the through hole 42 also have the same diameter and are the same drill bit in the same The drill floor is formed in the same way.

基板34在此繪示為一層壓結構,但基板34亦可為其他電性相連體,如陶瓷板或印刷電路板。同樣地,基板34可另包含複數個內嵌電路之層體。The substrate 34 is illustrated as a laminate structure, but the substrate 34 can also be other electrically connected bodies, such as ceramic plates or printed circuit boards. Similarly, the substrate 34 can further comprise a plurality of layers of embedded circuits.

圖4A至圖4L為剖視圖,說明本發明之一實施例中一種製作導熱板74之方法,該導熱板74包含導熱凸柱22、訊號凸柱24、基座26、黏著層28及基板34。圖4M及圖4N分別為圖4L之俯視圖及仰視圖。4A-4L are cross-sectional views illustrating a method of fabricating a thermally conductive plate 74 that includes a thermally conductive stud 22, a signal stud 24, a pedestal 26, an adhesive layer 28, and a substrate 34, in accordance with an embodiment of the present invention. 4M and 4N are a plan view and a bottom view, respectively, of FIG. 4L.

圖4A為黏著層28設置於基座26上之剖視圖。黏著層28係下降至基座26上,使導熱凸柱22向上***並貫穿開口30,而訊號凸柱24則向上***並貫穿開口32,最終則使黏著層28接觸並定位於基座26。較佳者,導熱凸柱22在***及貫穿開口30後係對準開口30且位於開口30內之中央位置但不接觸黏著層28;而訊號凸柱24在***及貫穿 開口32後亦對準開口32且位於開口32內之中央位置但不接觸黏著層28。4A is a cross-sectional view showing the adhesive layer 28 disposed on the susceptor 26. The adhesive layer 28 is lowered onto the base 26 such that the thermally conductive studs 22 are inserted upwardly through the opening 30, and the signal studs 24 are inserted upwardly through the opening 32, and finally the adhesive layer 28 is contacted and positioned on the base 26. Preferably, the thermally conductive stud 22 is aligned with the opening 30 after being inserted into and through the opening 30 and is located at a central position within the opening 30 but does not contact the adhesive layer 28; and the signal stud 24 is inserted and penetrated The opening 32 is also aligned with the opening 32 and is located centrally within the opening 32 but does not contact the adhesive layer 28.

在圖4B所示結構中,基板34係設置於黏著層28上。基板34係下降至黏著層28上,使導熱凸柱22向上***通孔40,而訊號凸柱24則向上***通孔42,最終則使基板34接觸並定位於黏著層28。In the structure shown in FIG. 4B, the substrate 34 is disposed on the adhesive layer 28. The substrate 34 is lowered onto the adhesive layer 28 such that the thermally conductive studs 22 are inserted upwardly into the through holes 40, and the signal studs 24 are inserted upwardly into the through holes 42 to ultimately contact and position the substrate 34 to the adhesive layer 28.

導熱凸柱22在***(但並未貫穿)通孔40後係對準通孔40且位於通孔40內之中央位置而不接觸基板34。因此,缺口44係位於通孔40內且介於導熱凸柱22與基板34之間。缺口44側向環繞導熱凸柱22,同時被基板34側向包圍。此外,開口30與通孔40係相互對齊且具有相同直徑。The thermally conductive stud 22 is aligned with the through hole 40 after being inserted (but not penetrating) through the through hole 40 and located at a central position within the through hole 40 without contacting the substrate 34. Therefore, the notch 44 is located in the through hole 40 and between the thermally conductive stud 22 and the substrate 34. The notch 44 laterally surrounds the thermally conductive stud 22 while being laterally surrounded by the substrate 34. Further, the opening 30 and the through hole 40 are aligned with each other and have the same diameter.

訊號凸柱24在***(但並未貫穿)通孔42後係對準通孔42且位於通孔42內之中央位置而不接觸基板34。因此,缺口46係位於通孔42內且介於訊號凸柱24與基板34之間。缺口46側向環繞訊號凸柱24,同時被基板34側向包圍。此外,開口32與通孔42係相互對齊且具有相同直徑。The signal stud 24 is aligned with the through hole 42 after insertion (but not through) the through hole 42 and is located at a central position within the through hole 42 without contacting the substrate 34. Therefore, the notch 46 is located in the through hole 42 and between the signal stud 24 and the substrate 34. The notch 46 laterally surrounds the signal stud 24 while being laterally surrounded by the substrate 34. Further, the opening 32 and the through hole 42 are aligned with each other and have the same diameter.

此時,基板34係安置於黏著層28上並與之接觸,且延伸於黏著層28上方。導熱凸柱22延伸通過開口30後,進入通孔40且到達介電層38。導熱凸柱22較導電層36之頂面低60微米,並經由通孔40朝一向上方向外露。訊號凸柱24延伸通過開口32後,進入通孔42且到達介電層38。訊號凸柱24較導電層36之頂面低60微米,並經由通孔 42朝該向上方向外露。黏著層28接觸基座26與基板34且介於該兩者之間。黏著層28接觸介電層38但與導電層36保持距離。在此階段,黏著層28仍為乙階(B-stage)未固化環氧樹脂之膠片,而缺口44、46中則為空氣。At this time, the substrate 34 is disposed on and in contact with the adhesive layer 28 and extends over the adhesive layer 28. After extending through the opening 30, the thermally conductive studs 22 enter the vias 40 and reach the dielectric layer 38. The thermally conductive studs 22 are 60 microns lower than the top surface of the conductive layer 36 and are exposed in an upward direction via the vias 40. After the signal studs 24 extend through the openings 32, they enter the vias 42 and reach the dielectric layer 38. The signal stud 24 is 60 microns lower than the top surface of the conductive layer 36 and passes through the through hole 42 is exposed in the upward direction. Adhesive layer 28 contacts pedestal 26 and substrate 34 and is interposed therebetween. Adhesive layer 28 contacts dielectric layer 38 but is at a distance from conductive layer 36. At this stage, the adhesive layer 28 is still a film of B-stage uncured epoxy, while the gaps 44, 46 are air.

圖4C繪示黏著層28經加熱加壓後流入缺口44、46。在此圖中,迫使黏著層28流入缺口44、46之方法係對導電層36施以向下壓力及/或對基座26施以向上壓力,亦即將基座26與基板34相對壓合,藉以對黏著層28施壓;在此同時亦對黏著層28加熱。受熱之黏著層28可在壓力下任意成形。因此,位於基座26與基板34間之黏著層28受到擠壓後,改變其原始形狀並向上流入缺口44、46。基座26與基板34持續朝彼此壓合,直到黏著層28填滿缺口44、46為止。此外,在基座26與基板34間之間隙縮小後,黏著層28仍舊填滿此一縮小之間隙內。4C illustrates the adhesive layer 28 flowing into the gaps 44, 46 after being heated and pressurized. In this figure, the method of forcing the adhesive layer 28 into the gaps 44, 46 is to apply downward pressure to the conductive layer 36 and/or apply upward pressure to the susceptor 26, that is, to press the susceptor 26 against the substrate 34, Thereby, the adhesive layer 28 is pressed; at the same time, the adhesive layer 28 is also heated. The heated adhesive layer 28 can be arbitrarily shaped under pressure. Therefore, after the adhesive layer 28 between the susceptor 26 and the substrate 34 is pressed, its original shape is changed and flows upward into the notches 44, 46. The susceptor 26 and the substrate 34 are continuously pressed against each other until the adhesive layer 28 fills the notches 44, 46. In addition, after the gap between the susceptor 26 and the substrate 34 is reduced, the adhesive layer 28 still fills the reduced gap.

例如,可將基座26及導電層36設置於一壓合機之上、下壓台(圖未示)之間。此外,可將一上擋板及上緩衝紙(圖未示)夾置於導電層36與上壓台之間,並將一下擋板及下緩衝紙(圖未示)夾置於基座26與下壓台之間。以此構成之疊合體由上到下依次為上壓台、上擋板、上緩衝紙、基板34、黏著層28、基座26、下緩衝紙、下擋板及下壓台。此外,可利用從下壓台向上延伸並穿過基座26對位孔(圖未示)之工具接腳(圖未示)將此疊合體定位於下壓台上。For example, the susceptor 26 and the conductive layer 36 can be disposed between a press machine and a lower pressing table (not shown). In addition, an upper baffle and an upper buffer paper (not shown) may be interposed between the conductive layer 36 and the upper pressing table, and the lower baffle and the lower cushioning paper (not shown) are placed on the base 26 . Between the lower pressing table. The stacked body thus constructed is, in order from top to bottom, an upper pressing table, an upper baffle plate, an upper baffle paper, a substrate 34, an adhesive layer 28, a susceptor 26, a lower cushioning paper, a lower baffle plate, and a lower pressing table. In addition, the stacking body can be positioned on the lower pressing table by means of a tool pin (not shown) extending upward from the lower pressing table and passing through a counter hole (not shown) of the base 26.

而後將上、下壓台加熱並相互推進,藉此對黏著層28加熱並施壓。擋板可將壓台之熱分散,使熱均勻施加於基 座26與基板34乃至於黏著層28。緩衝紙則將壓台之壓力分散,使壓力均勻施加於基座26與基板34乃至於黏著層28。起初,介電層38接觸並壓合於黏著層28。隨著壓台持續動作與持續加熱,基座26與基板34間之黏著層28受到擠壓並開始熔化,因而向上流入缺口44、46,並於通過介電層38後抵達導電層36。例如,未固化環氧樹脂遇熱熔化後,被壓力擠入缺口44、46中,但加強材料及填充物仍留在基座26與基板34之間。黏著層28在通孔40內上升之速度大於導熱凸柱22,終至填滿缺口44。黏著層28在通孔42內上升之速度亦大於訊號凸柱24,終至填滿缺口46。黏著層28亦上升至稍高於缺口44、46之位置,並在壓台停止動作前,溢流至導熱凸柱22頂面及導電層36頂面鄰接缺口44處,以及訊號凸柱24頂面及導電層36頂面鄰接缺口46處。若膠片厚度略大於實際所需便可能發生此一情形。如此一來,黏著層28便在導熱凸柱22頂面及訊號凸柱24頂面形成一覆蓋薄層。壓台在觸及導熱凸柱22及訊號凸柱24後停止動作,但仍持續對黏著層28加熱。The upper and lower press tables are then heated and pushed into each other, whereby the adhesive layer 28 is heated and pressed. The baffle can disperse the heat of the pressing table to uniformly apply heat to the base. The holder 26 and the substrate 34 are as an adhesive layer 28. The cushioning paper disperses the pressure of the platen so that the pressure is uniformly applied to the susceptor 26 and the substrate 34 or even the adhesive layer 28. Initially, the dielectric layer 38 contacts and is pressed against the adhesive layer 28. As the platen continues to operate and continues to heat, the adhesive layer 28 between the susceptor 26 and the substrate 34 is squeezed and begins to melt, thereby flowing upward into the notches 44, 46 and after reaching the conductive layer 36 after passing through the dielectric layer 38. For example, the uncured epoxy resin is melted into the gaps 44, 46 after being melted by heat, but the reinforcing material and the filler remain between the susceptor 26 and the substrate 34. The adhesive layer 28 rises faster in the through hole 40 than the thermally conductive stud 22, and finally fills the notch 44. The adhesive layer 28 also rises faster in the through hole 42 than the signal stud 24, and finally fills the notch 46. The adhesive layer 28 also rises slightly above the notches 44, 46 and overflows to the top surface of the thermally conductive stud 22 and the top surface of the conductive layer 36 adjacent the notch 44 and the top of the signal stud 24 before the platen stops operating. The top surface of the surface and conductive layer 36 abuts the notch 46. This can happen if the film thickness is slightly larger than actually needed. As a result, the adhesive layer 28 forms a thin layer of cover on the top surface of the heat conducting stud 22 and the top surface of the signal stud 24 . The platen stops after touching the thermally conductive studs 22 and the signal studs 24, but continues to heat the adhesive layer 28.

黏著層28於缺口44、46中向上流動之方向如圖中向上粗箭號所示,導熱凸柱22、訊號凸柱24與基座26相對於基板34之向上移動如向上細箭號所示,而基板34相對於導熱凸柱22、訊號凸柱24與基座26之向下移動則如向下細箭號所示。The direction in which the adhesive layer 28 flows upward in the notches 44, 46 is as shown by the upward bold arrow in the figure, and the thermal conductive post 22, the signal stud 24 and the pedestal 26 move upward relative to the substrate 34 as indicated by the upward arrow. The downward movement of the substrate 34 relative to the thermally conductive studs 22, the signal studs 24 and the pedestal 26 is as indicated by the downwardly thin arrows.

圖4D中之黏著層28已經固化。The adhesive layer 28 in Figure 4D has cured.

例如,壓台停止移動後仍持續夾合導熱凸柱22、訊號 凸柱24與基座26並供熱,藉此將已熔化之乙階(B-stage)環氧樹脂轉換為丙階(C-stage)固化或硬化之環氧樹脂。因此,環氧樹脂係以類似習知多層壓合之方式固化。環氧樹脂固化後,壓台分離,以便將結構體從壓合機中取出。For example, after the platen stops moving, the heat conducting stud 22 and the signal are continuously clamped. The studs 24 are heated with the susceptor 26, thereby converting the melted B-stage epoxy to a C-stage cured or hardened epoxy. Therefore, the epoxy resin is cured in a manner similar to conventional lamination. After the epoxy resin is cured, the platen is separated to remove the structure from the press.

固化之黏著層28在導熱凸柱22與基板34之間、訊號凸柱24與基板34之間以及基座26與基板34之間提供牢固之機械性連結。黏著層28可承受一般操作壓力而不致變形損毀,遇過大壓力時則僅暫時扭曲。再者,黏著層28可吸收導熱凸柱22與基板34之間、訊號凸柱24與基板34之間以及基座26與基板34之間的熱膨脹不匹配。The cured adhesive layer 28 provides a secure mechanical bond between the thermally conductive stud 22 and the substrate 34, between the signal studs 24 and the substrate 34, and between the pedestal 26 and the substrate 34. The adhesive layer 28 can withstand normal operating pressure without deformation and damage, and is only temporarily distorted when excessive pressure is applied. Furthermore, the adhesive layer 28 can absorb the thermal expansion mismatch between the thermally conductive studs 22 and the substrate 34, between the signal studs 24 and the substrate 34, and between the pedestal 26 and the substrate 34.

在此階段,導熱凸柱22、訊號凸柱24與導電層36大致共平面,而黏著層28與導電層36則延伸至一面朝該向上方向之頂面。例如,基座26與介電層38間之黏著層28厚120微米,較其初始厚度180微米減少60微米;亦即導熱凸柱22在通孔40中升高60微米,訊號凸柱24在通孔42中升高60微米,而基板34則相對於導熱凸柱22、訊號凸柱24下降60微米。導熱凸柱22及訊號凸柱24之高度300微米基本上等同於導電層36(30微米)、介電層38(150微米)與下方黏著層28(120微米)之結合高度。此外,導熱凸柱22仍位於開口30與通孔40內之中央位置並與基板34保持距離,訊號凸柱24仍位於開口32與通孔42內之中央位置並與基板34保持距離,而黏著層28則填滿基座26與基板34間之空間並填滿缺口44、46。例如,缺口44(以及導熱凸柱22與基板34間之黏著層28)在導熱凸柱22頂面 處寬75微米(即1150微米減去1000微米後除以2),缺口46(以及訊號凸柱24與基板34間之黏著層28)在訊號凸柱24頂面處寬75微米((450 300)/2)。黏著層28在缺口44、46內延伸跨越介電層38。換言之,缺口44中之黏著層28係沿該向上方向及一向下方向延伸並跨越缺口44外側壁之介電層38厚度,而缺口46中之黏著層28則沿該向上方向及該向下方向延伸並跨越缺口46外側壁之介電層38厚度。黏著層28亦包含缺口44、46上方之薄頂部分,其接觸導熱凸柱22、訊號凸柱24之頂面與導電層36之頂面並在導熱凸柱22、訊號凸柱24上方延伸10微米。At this stage, the thermally conductive studs 22, signal posts 24 and the conductive layer 36 are substantially coplanar, and the adhesive layer 28 and the conductive layer 36 extend to a top surface of the upward direction. For example, the adhesive layer 28 between the pedestal 26 and the dielectric layer 38 is 120 microns thicker, and is 60 microns smaller than its initial thickness of 180 microns; that is, the thermally conductive stud 22 is raised 60 microns in the through hole 40, and the signal studs 24 are The via 42 is raised by 60 microns, and the substrate 34 is lowered by 60 microns with respect to the thermally conductive stud 22 and the signal stud 24. The height of the thermally conductive studs 22 and the signal studs 24 is substantially equal to the combined height of the conductive layer 36 (30 microns), the dielectric layer 38 (150 microns) and the underlying adhesive layer 28 (120 microns). In addition, the heat conducting stud 22 is still located at a central position in the opening 30 and the through hole 40 and is spaced apart from the substrate 34. The signal stud 24 is still located at a central position in the opening 32 and the through hole 42 and is spaced apart from the substrate 34, and adhered. Layer 28 fills the space between pedestal 26 and substrate 34 and fills gaps 44,46. For example, the notch 44 (and the adhesive layer 28 between the thermally conductive stud 22 and the substrate 34) is on the top surface of the thermally conductive stud 22 At a width of 75 microns (i.e., 1150 microns minus 1000 microns divided by 2), the notch 46 (and the adhesion layer 28 between the signal studs 24 and the substrate 34) is 75 microns wider at the top surface of the signal studs 24 (450 300 )/2). Adhesive layer 28 extends across dielectric layer 38 within indentations 44,46. In other words, the adhesive layer 28 in the notch 44 extends along the upward direction and a downward direction and across the thickness of the dielectric layer 38 of the outer sidewall of the notch 44, and the adhesive layer 28 in the notch 46 is along the upward direction and the downward direction. The thickness of the dielectric layer 38 extends and spans the outer sidewall of the notch 46. The adhesive layer 28 also includes a thin top portion above the notches 44, 46 that contacts the top surface of the thermally conductive stud 22, the signal post 24 and the top surface of the conductive layer 36 and extends over the thermally conductive stud 22 and the signal studs 24 Micron.

在圖4E所示結構中,導熱凸柱22、訊號凸柱24、黏著層28及導電層36之頂部皆已去除。In the structure shown in FIG. 4E, the tops of the thermally conductive studs 22, the signal studs 24, the adhesive layer 28, and the conductive layer 36 have been removed.

導熱凸柱22、訊號凸柱24、黏著層28及導電層36之頂部係以研磨方式去除,例如以旋轉鑽石砂輪及蒸餾水處理結構體之頂部。起初,鑽石砂輪僅磨去黏著層28。持續研磨,則黏著層28因受磨表面下移而變薄。鑽石砂輪終將接觸導熱凸柱22、訊號凸柱24與導電層36(不必然同時),因而開始研磨導熱凸柱22、訊號凸柱24與導電層36。持續研磨後,導熱凸柱22、訊號凸柱24、黏著層28及導電層36均因受磨表面下移而變薄。研磨持續至去除所需厚度為止。之後,以蒸餾水沖洗結構體去除污物。The tops of the thermally conductive studs 22, signal posts 24, adhesive layer 28, and conductive layer 36 are removed by grinding, such as by rotating the diamond wheel and the top of the structured water. Initially, the diamond wheel only scratches the adhesive layer 28. With continuous grinding, the adhesive layer 28 becomes thinner as the surface to be worn is moved downward. The diamond wheel will eventually contact the thermally conductive stud 22, the signal stud 24 and the conductive layer 36 (not necessarily simultaneously), thus beginning to polish the thermally conductive stud 22, the signal stud 24 and the conductive layer 36. After continuous grinding, the thermally conductive studs 22, the signal studs 24, the adhesive layer 28, and the conductive layer 36 are all thinned by the worn surface being moved down. The grinding continues until the desired thickness is removed. Thereafter, the structure was rinsed with distilled water to remove dirt.

上述研磨步驟將黏著層28之頂部磨去25微米,將導熱凸柱22之頂部磨去15微米,將訊號凸柱24之頂部磨去15微米,並將導電層36之頂部磨去15微米。厚度減少對 導熱凸柱22、訊號凸柱24或黏著層28均無明顯影響,但導電層36之厚度卻從30微米大幅縮減至15微米。The grinding step removes the top of the adhesive layer 28 by 25 microns, the top of the thermally conductive stud 22 by 15 microns, the top of the signal stud 24 by 15 microns, and the top of the conductive layer 36 by 15 microns. Thickness reduction The thermally conductive studs 22, the signal studs 24, or the adhesive layer 28 have no significant effect, but the thickness of the conductive layer 36 is greatly reduced from 30 microns to 15 microns.

至此,導熱凸柱22、訊號凸柱24、黏著層28及導電層36係共同位於介電層38上方一面朝該向上方向之平滑拼接側頂面上。同樣地,導熱凸柱22、訊號凸柱24與黏著層28在基座26處係彼此共平面。At this point, the thermally conductive studs 22, the signal studs 24, the adhesive layer 28, and the conductive layer 36 are collectively located above the dielectric layer 38 toward the smooth splicing side top surface of the upward direction. Similarly, the thermally conductive studs 22, signal posts 24, and adhesive layer 28 are coplanar with each other at the pedestal 26.

圖4F所示之結構體具有導電層50,其係沉積於導熱凸柱22、訊號凸柱24、黏著層28及導電層36上。The structure shown in FIG. 4F has a conductive layer 50 deposited on the thermally conductive studs 22, the signal studs 24, the adhesive layer 28, and the conductive layer 36.

導電層50接觸導熱凸柱22、訊號凸柱24、黏著層28及導電層36,並從上方覆蓋此四者。例如,可將結構體浸入一活化劑溶液中,因而使黏著層28可與無電鍍銅產生觸媒反應,接著將一第一銅層以無電鍍被覆之方式設於導熱凸柱22、訊號凸柱24、黏著層28及導電層36上,然後將一第二銅層以電鍍方式設於該第一銅層上。第一銅層厚約2微米,第二銅層厚約13微米,故導電層50之總厚度約為15微米。如此一來,導電層36之厚度便增為約30微米(15+15)。導電層50係作為導熱凸柱22與訊號凸柱24之一覆蓋層及導電層36之一加厚層。為便於說明,導熱凸柱22、訊號凸柱24與導電層50以及導電層36與50均以單層顯示。由於銅為同質被覆,導熱凸柱22與導電層50間之界線、訊號凸柱24與導電層50間之界線以及導電層36與50間之界線(均以虛線繪示)可能不易察覺甚至無法察覺。然而,黏著層28與導電層50間之界線則清楚可見。The conductive layer 50 contacts the thermally conductive studs 22, the signal studs 24, the adhesive layer 28, and the conductive layer 36, and covers the four from above. For example, the structure can be immersed in an activator solution, so that the adhesive layer 28 can react with the electroless copper to generate a catalyst, and then a first copper layer is provided on the thermally conductive stud 22 and the signal convex in an electroless plating manner. On the pillar 24, the adhesive layer 28 and the conductive layer 36, a second copper layer is then electroplated on the first copper layer. The first copper layer is about 2 microns thick and the second copper layer is about 13 microns thick, so the total thickness of the conductive layer 50 is about 15 microns. As a result, the thickness of the conductive layer 36 is increased to about 30 microns (15 + 15). The conductive layer 50 serves as a thickening layer of the thermal conductive stud 22 and the signal bump 24 and the conductive layer 36. For convenience of description, the thermal conductive studs 22, the signal studs 24 and the conductive layer 50, and the conductive layers 36 and 50 are all shown in a single layer. Since the copper is a homogeneous coating, the boundary between the heat conducting stud 22 and the conductive layer 50, the boundary between the signal stud 24 and the conductive layer 50, and the boundary between the conductive layers 36 and 50 (both shown by dashed lines) may be difficult to detect or even aware. However, the boundary between the adhesive layer 28 and the conductive layer 50 is clearly visible.

圖4G所示結構體之上、下表面分別設有圖案化之蝕刻 阻層52與圖案化之蝕刻阻層54。圖示之圖案化之蝕刻阻層52、54均為類似於圖案化之蝕刻阻層16之光阻層。圖案化之蝕刻阻層52設有可選擇性曝露導電層50之圖案,而圖案化之蝕刻阻層54則設有可選擇性曝露基座26之圖案。A patterned etching is provided on the upper surface and the lower surface of the structure shown in FIG. 4G. The resist layer 52 and the patterned etch stop layer 54. The illustrated patterned etch stop layers 52, 54 are all photoresist layers similar to the patterned etch stop layer 16. The patterned etch stop layer 52 is provided with a pattern that selectively exposes the conductive layer 50, and the patterned etch stop layer 54 is provided with a pattern that selectively exposes the pedestal 26.

在圖4H所示之結構體中,導電層36、50已經由蝕刻去除其選定部分以形成圖案化之蝕刻阻層52所定義之圖案,而基座26也已經由蝕刻去除其選定部分以形成圖案化之蝕刻阻層54所定義之圖案。所述蝕刻係雙面濕式化學蝕刻,其與施用於金屬板10者相仿。例如,利用一頂部噴嘴(圖未示)及一底部噴嘴(圖未示)將化學蝕刻液分別噴灑於結構體之頂面及底面,或者將結構體浸入化學蝕刻液中。化學蝕刻液可蝕透導電層36、50以露出黏著層28及介電層38,因而將原本無圖案之導電層36、50轉變為圖案層。化學蝕刻液亦蝕透基座26以露出黏著層28。In the structure shown in FIG. 4H, the conductive layers 36, 50 have been removed by etching to select portions thereof to form a pattern defined by the patterned etch stop layer 52, and the pedestal 26 has also been removed by etching to select selected portions thereof. A pattern defined by the patterned etch stop layer 54. The etching is a two-sided wet chemical etching similar to that applied to the metal plate 10. For example, a top nozzle (not shown) and a bottom nozzle (not shown) are used to spray the chemical etching solution on the top and bottom surfaces of the structure, respectively, or to immerse the structure in the chemical etching solution. The chemical etchant etches through the conductive layers 36, 50 to expose the adhesive layer 28 and the dielectric layer 38, thereby converting the originally unpatterned conductive layers 36, 50 into a patterned layer. The chemical etchant also erodes the susceptor 26 to expose the adhesive layer 28.

在圖4I中,結構體上之圖案化蝕刻阻層52、54均已去除。去除圖案化之蝕刻阻層52、54之方式可與去除圖案化之蝕刻阻層16、全面覆蓋之蝕刻阻層18之方式相同。In Figure 4I, the patterned etch stop layers 52, 54 on the structure have been removed. The manner in which the patterned etch stop layers 52, 54 are removed may be the same as the manner in which the patterned etch stop layer 16 is removed and the etch stop layer 18 is completely covered.

蝕刻後之導電層36、50包含焊墊56與路由線58,而蝕刻後之導電層50則包含蓋體60。焊墊56與路由線58係導電層36、50受圖案化之蝕刻阻層52保護而未被蝕刻之部分,蓋體60則為導電層50受圖案化之蝕刻阻層52保護而未被蝕刻之部分。如此一來,導電層36、50便成為圖案層,其包含焊墊56與路由線58但不包含蓋體60。此外,路由線58為一銅導線,其接觸介電層38並延伸於其上方 ,同時鄰接且電性連結訊號凸柱24與焊墊56。The etched conductive layers 36, 50 include pads 56 and routing lines 58, and the etched conductive layer 50 includes a cover 60. The pad 56 and the routing line 58 are electrically protected layers 36, 50 protected by the patterned etch stop layer 52, and the cover 60 is protected by the patterned etch stop layer 52. Part of it. As such, the conductive layers 36, 50 become patterned layers that include the pads 56 and routing lines 58 but do not include the cover 60. In addition, routing line 58 is a copper wire that contacts dielectric layer 38 and extends above it. At the same time, the signal bumps 24 and the pads 56 are electrically connected adjacent to each other.

蝕刻後之基座26包含基座26(僅剩其中央部分)及端子62。基座26係原基座26受圖案化之蝕刻阻層54保護而未被蝕刻之部分,其沿側向延伸且於側面方向超出導熱凸柱22之外1000微米。端子62係原基座26受圖案化之蝕刻阻層54保護而未被蝕刻之部分,其鄰接訊號凸柱24,延伸於訊號凸柱24下方,且自訊號凸柱24側向延伸而出,同時接觸黏著層28並延伸於黏著層28下方。基座26仍為一無圖案層,但在基座26周緣之外則形成一包含端子62且與基座26保持側向間距之圖案層。因此,端子62與基座26係彼此分離,且端子62已非基座26之一部分。此外,訊號凸柱24鄰接路由線58與端子62並在路由線58與端子62之間形成電性連結。The etched susceptor 26 includes a pedestal 26 (only the central portion remains) and a terminal 62. The pedestal 26 is the portion of the original pedestal 26 that is protected by the patterned etch stop layer 54 and that is not etched, extending laterally and 1000 microns beyond the thermally conductive studs 22 in the lateral direction. The terminal 62 is a portion of the original pedestal 26 that is protected by the patterned etch stop layer 54 and is not etched. The adjacent signal post 24 extends below the signal stud 24 and extends laterally from the signal stud 24 . At the same time, the adhesive layer 28 is contacted and extends below the adhesive layer 28. The pedestal 26 is still a non-patterned layer, but a patterned layer comprising terminals 62 and laterally spaced from the pedestal 26 is formed outside the periphery of the pedestal 26. Therefore, the terminal 62 and the base 26 are separated from each other, and the terminal 62 is not part of the base 26. In addition, the signal studs 24 abut the routing line 58 and the terminal 62 and form an electrical connection between the routing line 58 and the terminal 62.

訊號凸柱24、焊墊56、路由線58及端子62共同形成導線64。訊號凸柱24及路由線58係焊墊56與端子62間之一導電路徑。導線64提供從焊墊56至端子62之垂直(由上至下)路由。導線64並不限於此一構型。舉例而言,上述導電路徑尚可包含貫穿介電層38之導電孔、額外之路由線(其位於介電層38之上方及/或下方)及被動元件(如設置於其他焊墊上之電阻與電容)。Signal bumps 24, pads 56, routing lines 58, and terminals 62 collectively form wires 64. The signal studs 24 and routing lines 58 are one of the conductive paths between the pads 56 and the terminals 62. Wire 64 provides a vertical (top to bottom) routing from pad 56 to terminal 62. The wire 64 is not limited to this configuration. For example, the conductive path may further include conductive vias through the dielectric layer 38, additional routing lines (which are above and/or below the dielectric layer 38), and passive components (such as resistors disposed on other pads). capacitance).

散熱座66包含導熱凸柱22、基座26及蓋體60。導熱凸柱22與基座26係一體成形。蓋體60位於導熱凸柱22之頂部上方,鄰接導熱凸柱22之頂部,同時從上方覆蓋導熱凸柱22之頂部,並由導熱凸柱22之頂部往側向延伸。 設置蓋體60後,導熱凸柱22係坐落於蓋體60圓周內之中央區域。蓋體60亦接觸並從上方覆蓋其下方黏著層28之一部分,黏著層28之該部分係與導熱凸柱22共平面,鄰接導熱凸柱22,且側向包圍導熱凸柱22。The heat sink 66 includes a heat conductive stud 22, a base 26 and a cover 60. The thermally conductive stud 22 is integrally formed with the base 26. The cover 60 is located above the top of the thermally conductive stud 22 adjacent to the top of the thermally conductive stud 22 while covering the top of the thermally conductive stud 22 from above and extending laterally from the top of the thermally conductive stud 22. After the cover 60 is disposed, the thermally conductive studs 22 are located in a central region within the circumference of the cover 60. The cover 60 also contacts and covers a portion of the adhesive layer 28 therebelow from above. The portion of the adhesive layer 28 is coplanar with the thermally conductive studs 22, abuts the thermally conductive studs 22, and laterally surrounds the thermally conductive studs 22.

散熱座66實質上為一倒T形之散熱塊,其包含柱部(導熱凸柱22)、翼部(基座26自柱部側向延伸之部分)以及一導熱墊(蓋體60)。The heat sink 66 is substantially an inverted T-shaped heat sink block including a post portion (thermal conductive stud 22), a wing portion (a portion of the base 26 extending laterally from the post portion), and a thermal pad (cover 60).

圖4J之結構體在黏著層28、介電層38、導電層50及蓋體60上設有防焊綠漆68,並且在基座26、黏著層28及端子62上設有防焊綠漆70。The structure of FIG. 4J is provided with a solder resist green paint 68 on the adhesive layer 28, the dielectric layer 38, the conductive layer 50 and the cover 60, and the solder resist green paint is provided on the base 26, the adhesive layer 28 and the terminal 62. 70.

防焊綠漆68為一電性絕緣層,其可依吾人之選擇形成圖案以曝露焊墊56與蓋體60,並從上方覆蓋路由線58、黏著層28之外露部分及介電層38之外露部分。防焊綠漆68在焊墊56與蓋體60上方之厚度為25微米,且防焊綠漆68於介電層38上方延伸55微米(30+25)。The solder resist green paint 68 is an electrical insulating layer which can be patterned to expose the solder pad 56 and the cover 60, and covers the routing line 58, the exposed portion of the adhesive layer 28 and the dielectric layer 38 from above. Exposed part. The solder resist green lacquer 68 has a thickness of 25 microns above the pad 56 and the cover 60, and the solder resist green lacquer 68 extends 55 microns (30+25) above the dielectric layer 38.

防焊綠漆70為一電性絕緣層,其可依吾人之選擇形成圖案以曝露基座26與端子62,並從下方覆蓋黏著層28之外露部分。防焊綠漆70在基座26與端子62下方之厚度為25微米,且防焊綠漆70於黏著層28下方延伸55微米(30+25)。The solder resist green paint 70 is an electrically insulating layer that can be patterned to expose the pedestal 26 and the terminal 62 and to cover the exposed portion of the adhesive layer 28 from below. The solder resist green lacquer 70 has a thickness of 25 microns below the pedestal 26 and the terminal 62, and the solder resist green lacquer 70 extends 55 microns (30+25) below the adhesive layer 28.

防焊綠漆68、70起初為塗佈於結構體上之一光顯像型液態樹脂。之後再於防焊綠漆68、70上形成圖案,其作法係令光線選擇性透過光罩(圖未示),使受光之部分防焊綠漆變為不可溶解,然後利用一顯影溶液去除未受光且仍可溶 解之部分防焊綠漆,最後再進行硬烤,以上步驟乃習知技藝。The solder resist green paints 68 and 70 were originally coated with a light-developing liquid resin on the structure. Then, a pattern is formed on the solder resist green paints 68 and 70. The method is to selectively pass light through the mask (not shown), so that the portion of the light-shielded green paint becomes insoluble, and then removes the solution by using a developing solution. Light and still soluble Part of the anti-weld green paint is solved, and finally hard baking is performed. The above steps are known techniques.

圖4K所示結構體之基座26、焊墊56、蓋體60與端子62上設有被覆接點72。The base 26, the pad 56, the cover 60, and the terminal 62 of the structure shown in Fig. 4K are provided with covered contacts 72.

被覆接點72為一多層金屬鍍層,其接觸基座26與端子62並從下方覆蓋其外露之部分,同時接觸焊墊56與蓋體60並從上方覆蓋其外露之部分。例如,一鎳層係以無電鍍被覆之方式設於基座26、焊墊56、蓋體60與端子62上,而後再將一金層以無電鍍被覆之方式設於該鎳層上,其中內部鎳層厚約3微米,表面金層厚約0.5微米,故被覆接點72之厚度約為3.5微米。The coated contact 72 is a multi-layer metal coating that contacts the pedestal 26 and the terminal 62 and covers the exposed portion thereof from below while contacting the pad 56 and the cover 60 and covering the exposed portion thereof from above. For example, a nickel layer is provided on the susceptor 26, the pad 56, the cover 60 and the terminal 62 in an electroless plating manner, and then a gold layer is provided on the nickel layer in an electroless plating manner, wherein The inner nickel layer is about 3 microns thick and the surface gold layer is about 0.5 microns thick, so the thickness of the coated contact 72 is about 3.5 microns.

以被覆接點72作為基座26、焊墊56、蓋體60與端子62之表面處理具有幾項優點。內部鎳層提供主要之機械性與電性連結及/或熱連結,而表面金層則提供一可濕性表面以利焊料迴焊。被覆接點72亦保護基座26、焊墊56、蓋體60與端子62不受腐蝕。被覆接點72可包含各種金屬以符合外部連結媒介之需要。例如,一被覆在鎳層上之銀層可搭配焊錫或打線。The surface treatment with the covered contacts 72 as the pedestal 26, the pads 56, the cover 60 and the terminals 62 has several advantages. The inner nickel layer provides primary mechanical and electrical bonding and/or thermal bonding, while the surface gold layer provides a wettable surface for solder reflow. The covered contacts 72 also protect the susceptor 26, the pads 56, the cover 60 and the terminals 62 from corrosion. The coated contacts 72 can contain a variety of metals to meet the needs of externally coupled media. For example, a layer of silver coated on a nickel layer can be soldered or wired.

為便於說明,設有被覆接點72之基座26、焊墊56、蓋體60與端子62均以單一層體方式顯示。被覆接點72與基座26、焊墊56、蓋體60及端子62間之界線(圖未示)為銅/鎳介面。For convenience of explanation, the susceptor 26 provided with the covered contacts 72, the pads 56, the cover 60 and the terminals 62 are all displayed in a single layer. The boundary (not shown) between the covered contact 72 and the susceptor 26, the pad 56, the cover 60 and the terminal 62 is a copper/nickel interface.

至此完成導熱板74之製作。The fabrication of the heat conducting plate 74 is thus completed.

圖4L、圖4M及圖4N分別為導熱板74之剖視圖、俯 視圖及仰視圖,圖中導熱板74之邊緣已沿切割線而與支撐架及/或同批生產之相鄰導熱板分離。4L, 4M, and 4N are cross-sectional views of the heat conducting plate 74, respectively. View and bottom view, the edges of the heat conducting plate 74 in the figure have been separated along the cutting line from the support frame and/or the adjacent heat transfer plates produced in the same batch.

導熱板74包含黏著層28、基板34、導線64、散熱座66及防焊綠漆68、70。基板34包含介電層38。導線64包含訊號凸柱24、焊墊56、路由線58及端子62。散熱座66包含導熱凸柱22、基座26及蓋體60。The heat conducting plate 74 includes an adhesive layer 28, a substrate 34, a wire 64, a heat sink 66, and solder resist green paints 68, 70. Substrate 34 includes a dielectric layer 38. Wire 64 includes signal studs 24, pads 56, routing lines 58, and terminals 62. The heat sink 66 includes a heat conductive stud 22, a base 26 and a cover 60.

導熱凸柱22延伸貫穿開口30並進入通孔40後,仍位於開口30與通孔40內之中央位置。導熱凸柱22之頂部係與黏著層28位於介電層38上方之一相鄰部分共平面,而導熱凸柱22之底部則與黏著層28其接觸基座26之一相鄰部分共平面。導熱凸柱22保持平頂錐柱形,其漸縮側壁使其直徑自基座26朝導熱凸柱22鄰接蓋體60之平坦圓頂向上遞減。After the heat conducting stud 22 extends through the opening 30 and enters the through hole 40, it is still located at a central position within the opening 30 and the through hole 40. The top of the thermally conductive stud 22 is coplanar with an adjacent portion of the adhesive layer 28 above the dielectric layer 38, and the bottom of the thermally conductive stud 22 is coplanar with an adjacent portion of the adhesive layer 28 that contacts the pedestal 26. The thermally conductive studs 22 maintain a flat-topped tapered cylindrical shape with tapered side walls that decrease in diameter from the base 26 toward the flattened dome of the thermally conductive stud 22 adjacent the cover 60.

訊號凸柱24延伸貫穿開口32並進入通孔42後,仍位於開口32與通孔42內之中央位置。訊號凸柱24之頂部係與黏著層28位於介電層38上方之一相鄰部分共平面,而訊號凸柱24之底部則與黏著層28其接觸端子62之一相鄰部分共平面。訊號凸柱24保持平頂錐柱形,其漸縮側壁使其直徑自端子62朝訊號凸柱24鄰接路由線58之平坦圓頂向上遞減。After the signal stud 24 extends through the opening 32 and enters the through hole 42, it is still located at a central position within the opening 32 and the through hole 42. The top of the signal stud 24 is coplanar with an adjacent portion of the adhesive layer 28 above the dielectric layer 38, and the bottom of the signal stud 24 is coplanar with an adjacent portion of the adhesive layer 28 that contacts the terminal 62. The signal studs 24 maintain a flat-topped tapered cylindrical shape with tapered side walls that decrease in diameter from the terminal 62 toward the flat dome of the signal post 24 adjacent the routing line 58.

基座26從下方覆蓋導熱凸柱22與蓋體60,且與導熱板74之外圍邊緣保持距離。The pedestal 26 covers the thermally conductive stud 22 and the cover 60 from below and is spaced from the peripheral edge of the thermally conductive plate 74.

蓋體60位於導熱凸柱22上方,與之鄰接並為熱連結。蓋體60同時從上方覆蓋導熱凸柱22之頂部,並自導熱 凸柱22頂部沿側向延伸。蓋體60亦從上方接觸並覆蓋黏著層28之一部分,黏著層28之該部分係鄰接導熱凸柱22,與導熱凸柱22共平面,且側向環繞導熱凸柱22。蓋體60亦與焊墊56共平面。The cover 60 is located above the thermally conductive stud 22 adjacent thereto and is thermally coupled. The cover body 60 simultaneously covers the top of the heat conducting stud 22 from above and is self-conducting The top of the stud 22 extends laterally. The cover 60 also contacts and covers a portion of the adhesive layer 28 from above, the portion of the adhesive layer 28 abutting the thermally conductive studs 22, coplanar with the thermally conductive studs 22, and laterally surrounding the thermally conductive studs 22. The cover 60 is also coplanar with the pads 56.

黏著層28係設置於基座26上並於其上方延伸。黏著層28在缺口44內接觸且介於導熱凸柱22與介電層38之間,並填滿導熱凸柱22與介電層38間之空間。黏著層28在缺口46內接觸且介於訊號凸柱24與介電層38之間,並填滿訊號凸柱24與介電層38間之空間。黏著層28在缺口44、46外則接觸且介於基座26與介電層38之間,並填滿基座26與介電層38間之空間。黏著層28係從導熱凸柱22側向延伸並越過端子62,重疊於端子62,並從上方覆蓋基座26位於導熱凸柱22周緣外之一部分,同時沿側面方向覆蓋且環繞導熱凸柱22與訊號凸柱24。黏著層28亦填滿基板34與散熱座66間之絕大部分空間。此時黏著層28已固化。The adhesive layer 28 is disposed on the base 26 and extends above it. The adhesive layer 28 contacts the gap between the thermally conductive studs 22 and the dielectric layer 38 and fills the space between the thermally conductive studs 22 and the dielectric layer 38. The adhesive layer 28 contacts the gap 46 between the signal stud 24 and the dielectric layer 38 and fills the space between the signal studs 24 and the dielectric layer 38. Adhesive layer 28 contacts outside of gaps 44, 46 and is interposed between susceptor 26 and dielectric layer 38 and fills the space between pedestal 26 and dielectric layer 38. The adhesive layer 28 extends laterally from the thermally conductive stud 22 and over the terminal 62, overlying the terminal 62, and covers the pedestal 26 from above with a portion outside the periphery of the thermally conductive stud 22 while covering in the lateral direction and surrounding the thermally conductive stud 22 And the signal studs 24. Adhesive layer 28 also fills most of the space between substrate 34 and heat sink 66. At this point the adhesive layer 28 has cured.

基板34係設置於黏著層28上並與之接觸。此外,基板34延伸於其下方黏著層28之上方,且延伸於基座26上方。導電層36(以及焊墊56與路由線58)接觸介電層38並延伸於其上方,而介電層38則接觸且介於黏著層28與導電層36之間。The substrate 34 is disposed on and in contact with the adhesive layer 28. In addition, the substrate 34 extends above the underlying adhesive layer 28 and over the susceptor 26. Conductive layer 36 (and pad 56 and routing line 58) contact dielectric layer 38 and extend thereover, while dielectric layer 38 contacts and is between adhesive layer 28 and conductive layer 36.

導熱凸柱22與訊號凸柱24具有相同厚度且彼此共平面。基座26與端子62具有相同厚度且彼此共平面。此外,導熱凸柱22、訊號凸柱24之頂部及底部均與黏著層28 共平面。The thermally conductive studs 22 have the same thickness as the signal studs 24 and are coplanar with each other. The pedestal 26 has the same thickness as the terminals 62 and is coplanar with each other. In addition, the thermal conductive studs 22, the top and bottom of the signal studs 24 and the adhesive layer 28 Coplanar.

導熱凸柱22、訊號凸柱24、基座26、蓋體60及端子62均與基板34保持距離。因此,基板34與散熱座66係機械性連接且彼此電性隔離。The thermally conductive studs 22, the signal studs 24, the pedestal 26, the cover 60, and the terminals 62 are all spaced from the substrate 34. Therefore, the substrate 34 is mechanically coupled to the heat sink 66 and electrically isolated from each other.

同批製作之導熱板74經裁切後,其黏著層28、介電層38及防焊綠漆68、70均延伸至裁切而成之垂直邊緣。After the same batch of thermally conductive plates 74 are cut, the adhesive layer 28, the dielectric layer 38 and the solder resist green paints 68, 70 extend to the cut vertical edges.

焊墊56係一專為LED封裝體或半導體晶片等半導體元件量身訂做之電性介面,該半導體元件將於後續製程中設置於蓋體60上。端子62係一專為下一層組體(例如來自一印刷電路板之可焊接線)量身訂做之電性介面。蓋體60係一專為該半導體元件量身訂做之熱介面。基座26係一專為下一層組體(例如前述印刷電路板或一電子設備之散熱裝置)量身訂做之熱介面。此外,蓋體60係經由導熱凸柱22而熱連結至基座26。The pad 56 is an electrical interface tailored to a semiconductor component such as an LED package or a semiconductor wafer, and the semiconductor component is disposed on the cover 60 in a subsequent process. Terminal 62 is an electrical interface tailored to the next layer of components (e.g., solderable wires from a printed circuit board). The cover 60 is a thermal interface tailored to the semiconductor component. The pedestal 26 is a thermal interface tailored to the next layer of components, such as the aforementioned printed circuit board or a heat sink for an electronic device. Further, the cover 60 is thermally coupled to the susceptor 26 via the thermally conductive studs 22 .

焊墊56與端子62在垂直方向上彼此錯位,且分別外露於導熱板74之頂面及底面,藉此提供該半導體元件與下一層組體間之垂直路由。The pad 56 and the terminal 62 are offset from each other in the vertical direction, and are respectively exposed on the top surface and the bottom surface of the heat conducting plate 74, thereby providing a vertical route between the semiconductor element and the next layer assembly.

焊墊56與蓋體60兩者之頂面於介電層38上方為共平面,而基座26與端子62兩者之底面則於黏著層28下方為共平面。The top surface of both the pad 56 and the cover 60 is coplanar above the dielectric layer 38, and the bottom surfaces of both the pedestal 26 and the terminal 62 are coplanar below the adhesive layer 28.

為便於說明,導線64於剖視圖中係繪示為一連續電路跡線。然而,導線64通常同時提供X與Y方向之水平訊號路由,亦即焊墊56與端子62彼此在X與Y方向形成側向錯位,而路由線58則構成X與Y方向之路徑。For ease of illustration, the wire 64 is depicted as a continuous circuit trace in cross-sectional view. However, the wires 64 typically provide horizontal signal routing in the X and Y directions, i.e., the pads 56 and the terminals 62 are laterally offset from each other in the X and Y directions, and the routing lines 58 form the path in the X and Y directions.

散熱座66可將隨後設置於蓋體60上之半導體元件所產生之熱能擴散至導熱板74所連接之下一層組體。該半導體元件產生之熱能流入蓋體60,自蓋體60進入導熱凸柱22,並經由導熱凸柱22進入基座26。熱能從基座26沿該向下方向散出,例如擴散至一下方散熱裝置。The heat sink 66 can diffuse the thermal energy generated by the semiconductor component subsequently disposed on the cover 60 to a lower group to which the heat conducting plate 74 is connected. The thermal energy generated by the semiconductor component flows into the cover 60, enters the thermally conductive stud 22 from the cover 60, and enters the susceptor 26 via the thermally conductive stud 22. Thermal energy is dissipated from the susceptor 26 in the downward direction, for example, to a lower heat sink.

導熱板74之導熱凸柱22、訊號凸柱24與路由線58均未外露,其中導熱凸柱22被蓋體60覆蓋,訊號凸柱24及路由線58係由防焊綠漆68覆蓋,而黏著層28則同時由防焊綠漆68、70覆蓋。為便於說明,圖4M以虛線繪示導熱凸柱22、訊號凸柱24、黏著層28與路由線58。The heat conducting studs 22, the signal studs 24 and the routing wires 58 of the heat conducting plate 74 are not exposed, wherein the heat conducting studs 22 are covered by the cover 60, and the signal studs 24 and the routing wires 58 are covered by the solder resist green paint 68. The adhesive layer 28 is simultaneously covered by the solder resist green paints 68, 70. For convenience of description, FIG. 4M shows the heat conducting stud 22, the signal stud 24, the adhesive layer 28 and the routing line 58 in broken lines.

導熱板74亦包含其他導線64,該些導線64基本上係由訊號凸柱24、焊墊56、路由線58與端子62所構成。為便於說明,在此僅說明並繪示單一導線64。於導線64中,訊號凸柱24、焊墊56及端子62通常具有相同之形狀及尺寸,而路由線58則通常採用不同之路由構型。例如,部分導線64設有間距,彼此分離,且為電性隔離,而部分導線64則彼此交錯或導向同一焊墊56、路由線58或端子62且彼此電性連結。同樣地,部分焊墊56可用以接收獨立訊號,而部分焊墊56則共用一訊號、電源或接地端。The heat conducting plate 74 also includes other wires 64 that are substantially comprised of signal posts 24, pads 56, routing lines 58, and terminals 62. For ease of explanation, only a single wire 64 is illustrated and illustrated herein. In the wire 64, the signal posts 24, pads 56 and terminals 62 generally have the same shape and size, while the routing wires 58 are typically of a different routing configuration. For example, portions of the wires 64 are spaced apart from each other and electrically isolated, and the partial wires 64 are staggered or directed to the same pad 56, routing line 58 or terminal 62 and electrically coupled to each other. Similarly, a portion of the pads 56 can be used to receive independent signals, while a portion of the pads 56 share a signal, power supply, or ground.

導熱板74可適用於具有藍、綠及紅色LED晶片之LED封裝體,其中各LED晶片包含一陽極與一陰極,且各LED封裝體包含對應之陽極端子與陰極端子。在此例中,導熱板74可包含六個焊墊56與四個端子62,以便將每一陽極從一獨立焊墊56導向一獨立端子62,並將每一陰極從 一獨立焊墊56導向一共同之接地端子62。The heat conducting plate 74 can be applied to an LED package having blue, green, and red LED chips, wherein each LED chip includes an anode and a cathode, and each LED package includes a corresponding anode terminal and cathode terminal. In this example, the thermally conductive plate 74 can include six pads 56 and four terminals 62 to direct each anode from a separate pad 56 to a separate terminal 62, and each cathode is A separate pad 56 is directed to a common ground terminal 62.

在各製造階段均可利用一簡易清潔步驟去除外露金屬上之氧化物與殘留物,例如可對本案結構體施行一短暫之氧電漿清潔步驟。或者,可利用一過錳酸鉀溶液對本案結構體進行一短暫之濕式化學清潔步驟。同樣地,亦可利用蒸餾水淋洗本案結構體以去除污物。此清潔步驟可清潔所需表面而不對結構體造成明顯之影響或破壞。A simple cleaning step can be used at each stage of manufacture to remove oxides and residues from the exposed metal. For example, a short oxygen plasma cleaning step can be applied to the structure of the present invention. Alternatively, the structure of the present invention can be subjected to a brief wet chemical cleaning step using a potassium permanganate solution. Similarly, the structure can be rinsed with distilled water to remove dirt. This cleaning step cleans the desired surface without causing significant damage or damage to the structure.

本案之優點在於導線64形成後不需從中分離或分割出匯流點或相關電路系統。匯流點可於形成焊墊56、路由線58、蓋體60與端子62之濕式化學蝕刻步驟中分離。The advantage of this case is that there is no need to separate or separate the confluence points or associated circuitry from the wires 64 after they are formed. The sink point can be separated during the wet chemical etching step of forming pad 56, routing line 58, cover 60 and terminal 62.

導熱板74可包含鑽透或切通黏著層28、基板34與防焊綠漆68、70而形成之對位孔(圖未示)。如此一來,當導熱板74需於後續製程中設置於一下方載體時,便可將工具接腳***對位孔中,藉以將導熱板74置於定位。The heat conducting plate 74 may include a counter hole (not shown) formed by drilling or cutting through the adhesive layer 28, the substrate 34 and the solder resist green paint 68, 70. In this way, when the heat conducting plate 74 needs to be disposed on a lower carrier in a subsequent process, the tool pin can be inserted into the alignment hole to position the heat conducting plate 74.

導熱板74可略去蓋體60。欲達此一目的,可調整圖案化之蝕刻阻層52,使整個通孔40上方之導電層50均曝露於用以形成焊墊56及路由線58之化學蝕刻液中。略去蓋體60之另一作法係不設導電層50。The cover 60 can be omitted from the heat conducting plate 74. To achieve this, the patterned etch stop layer 52 can be adjusted such that the conductive layer 50 over the entire via 40 is exposed to the chemical etchant used to form the pads 56 and routing lines 58. Another method of omitting the cover 60 is to provide no conductive layer 50.

導熱板74可容納多個半導體元件而非僅容納單一半導體元件。欲達此一目的,可調整圖案化之蝕刻阻層16以定義更多導熱凸柱22與訊號凸柱24,調整黏著層28以包含更多開口30、32,調整基板34以包含更多通孔40、42,調整圖案化之蝕刻阻層52以定義更多焊墊56、路由線58與蓋體60,並調整防焊綠漆68以包含更多開口。端子62 以外之元件可改變側向位置以便為四個半導體元件提供一2x2陣列。此外,部分但非所有元件之剖面形狀及高低(即側面形狀)亦可有所調整。例如,焊墊56、蓋體60與端子62可保持相同之側面形狀,而路由線58則具有不同之路由構型。The heat conducting plate 74 can accommodate a plurality of semiconductor components instead of only a single semiconductor component. To achieve this, the patterned etch stop layer 16 can be modified to define more thermally conductive posts 22 and signal posts 24, the adhesive layer 28 can be adjusted to include more openings 30, 32, and the substrate 34 can be adjusted to include more passes. The holes 40, 42 are patterned to etch the etch stop layer 52 to define more pads 56, routing lines 58 and cover 60, and to adjust the solder resist green lacquer 68 to include more openings. Terminal 62 Components other than the ones can change the lateral position to provide a 2x2 array for the four semiconductor components. In addition, the cross-sectional shape and height (ie, side shape) of some but not all components may be adjusted. For example, pad 56, cover 60 and terminal 62 may maintain the same side shape, while routing line 58 has a different routing configuration.

圖5A、圖5B及圖5C分別為本發明一實施例中一導熱板76之剖視圖、俯視圖及仰視圖,該導熱板76在其黏著層28上設有一導線64。5A, 5B, and 5C are respectively a cross-sectional view, a top view, and a bottom view of a heat conducting plate 76 according to an embodiment of the present invention. The heat conducting plate 76 is provided with a wire 64 on the adhesive layer 28.

本實施例省略介電層38,且導線64係與黏著層28接觸。為求簡明,凡導熱板74之相關說明適用於此實施例者均併入此處,相同之說明不予重覆。同樣地,本實施例導熱板76之元件與導熱板74之元件相仿者,均採對應之參考標號。In this embodiment, the dielectric layer 38 is omitted and the wires 64 are in contact with the adhesive layer 28. For the sake of brevity, the description of the heat conducting plate 74 is applicable to this embodiment, and the same description will not be repeated. Similarly, the components of the heat conducting plate 76 of this embodiment are similar to those of the heat conducting plate 74, and corresponding reference numerals are used.

導熱板76包含黏著層28、導線64、散熱座66與防焊綠漆68、70。導線64包含訊號凸柱24、焊墊56、路由線58與端子62。散熱座66包含導熱凸柱22、基座26與蓋體60。The thermally conductive plate 76 includes an adhesive layer 28, wires 64, heat sinks 66 and solder resist green paints 68,70. Wire 64 includes signal studs 24, pads 56, routing lines 58, and terminals 62. The heat sink 66 includes a heat conductive stud 22, a base 26 and a cover 60.

本實施例之導電層36較前一實施例為厚。例如,導電層36之厚度由前一實施例中之30微米增為130微米,如此一來,導電層36便不至於在搬動時彎曲晃動。焊墊56與路由線58之厚度也因此增加,且焊墊56與路由線58均接觸並重疊於黏著層28。導熱板76並無對應於介電層38之介電層。The conductive layer 36 of this embodiment is thicker than the previous embodiment. For example, the thickness of the conductive layer 36 is increased from 30 micrometers to 130 micrometers in the previous embodiment, so that the conductive layer 36 does not bend and sway during handling.

In this way, an adhesive layer having a lower thermal conductivity can be used, thereby greatly reducing the cost. The heat sink can include an integrally formed thermally conductive stud and a base, and a cover body that is metallurgically bonded and thermally coupled to the thermally conductive stud, thereby improving reliability and reducing cost. The cover can be coplanar with the pad to form electrical, thermal, and mechanical bonds with the semiconductor component. In addition, the cover may be tailored to the semiconductor component, and the pedestal may be tailored to the next layer of the body to enhance thermal bonding from the semiconductor component to the next layer.

For example, the second conductive layer on the polished surface may include a routing line extending between the substrate and the cover through the adhesive layer, thereby electrically connecting the semiconductor element to the heat dissipation. seat. Thereafter, the heat sink can be electrically grounded to electrically ground the semiconductor component.

該散熱座可為銅質、鋁質、銅/鎳/鋁合金或其他導熱金屬結構。The heat sink can be copper, aluminum, copper/nickel/aluminum alloy or other thermally conductive metal structure.

該導熱凸柱可沉積於該基座上或與該基座一體成形。該導熱凸柱可與該基座一體成形,因而成為單一金屬體(如銅或鋁)。該導熱凸柱亦可與該基座一體成形,使該兩者之介面包含單一金屬體(例如銅),至於他處則包含其他金屬(例如凸柱之上部為焊料,凸柱之下部及基座則為銅質)。該導熱凸柱亦可與該基座一體成形,使該兩者之介面包含多層單一金屬體(例如在一鋁核心外設有一鎳緩衝層,而該鎳緩衝層上則設有一銅層)。The thermally conductive stud can be deposited on the base or integrally formed with the base. The thermally conductive stud can be integrally formed with the base and thus become a single metal body (such as copper or aluminum).

The thermally conductive stud can also be integrally formed with the base such that the interface between the two comprises a plurality of layers of a single metal body (eg, a nickel buffer layer on an aluminum core peripheral and a copper layer on the nickel buffer layer).

該訊號凸柱可沉積於該端子上或與該端子一體成形。該訊號凸柱可與該端子一體成形,因而成為單一金屬體(如銅或鋁)。該訊號凸柱亦可與該端子一體成形,使該兩者之介面包含單一金屬體(例如銅),至於他處則包含其他金屬(例如凸柱之上部為焊料,凸柱之下部及端子則為銅質)。該訊號凸柱亦可與該端子一體成形,使該兩者之介面包含多層單一金屬體(例如在一鋁核心外設有一鎳緩衝層,而該鎳 緩衝層上則設有一銅層)。The signal stud can be deposited on the terminal or integrally formed with the terminal. The signal stud can be integrally formed with the terminal and thus becomes a single metal body (such as copper or aluminum). The signal stud can also be integrally formed with the terminal such that the interface between the two comprises a single metal body (for example, copper), and other portions include other metals (for example, the upper portion of the stud is solder, the lower portion of the stud and the terminal For copper). The signal stud can also be integrally formed with the terminal such that the interface between the two comprises a plurality of single metal bodies (for example, a nickel buffer layer is disposed on an aluminum core peripheral, and the nickel A buffer layer is provided on the buffer layer).

該導熱凸柱可包含一平坦之頂面,且該頂面係與該黏著層共平面。例如,該導熱凸柱可與該黏著層共平面,或者該導熱凸柱可在該黏著層固化後接受蝕刻,因而在該導熱凸柱上方之黏著層形成一凹穴。吾人亦可選擇性蝕刻該導熱凸柱,藉以在該導熱凸柱中形成一延伸至其頂面下方之凹穴。在上述任一情況下,該半導體元件均可設置於該導熱凸柱上並位於該凹穴中,而該打線則可從該凹穴內之該半導體元件延伸至該凹穴外之該焊墊。在此情況下,該半導體元件可為一LED晶片,並由該凹穴將LED光線朝該向上方向聚焦。The thermally conductive stud may include a flat top surface and the top surface is coplanar with the adhesive layer. For example, the thermally conductive stud may be coplanar with the adhesive layer, or the thermally conductive stud may be etched after the adhesive layer is cured, such that the adhesive layer over the thermally conductive stud forms a recess. The thermally conductive stud can also be selectively etched to form a recess extending into the thermally conductive stud below its top surface. In any of the above cases, the semiconductor component may be disposed on the thermally conductive stud and located in the recess, and the bonding wire may extend from the semiconductor component in the recess to the pad outside the recess . In this case, the semiconductor component can be an LED wafer and the LED light is focused by the recess toward the upward direction.

For example, the susceptor can prevent the substrate from being bent and deformed during metal grinding, wafer placement, wire bonding, and molding of the packaging material. Additionally, the back of the base may include fins that project in the downward direction. For example, a rig can be used to cut the bottom surface of the pedestal to form lateral grooves, and the lateral grooves are fins. In this case, the pedestal may have a thickness of 500 microns, and the depth of the grooves may be 300 microns, that is, the height of the fins may be 300 microns. The fins may increase the surface area of the susceptor, and if the fins are exposed to the air rather than being disposed on a heat sink, the thermal conductivity of the susceptor via thermal convection may be enhanced.

該蓋體可於該黏著層固化後,該焊墊及/或該端子形成之前、中或後,以多種沉積技術製成,包括以電鍍、無電鍍被覆、蒸發及噴濺等技術形成單層或多層結構。該蓋體 可採用與該導熱凸柱相同之金屬材質,或採用與鄰接該蓋體之導熱凸柱頂部相同之金屬材質。此外,該蓋體可跨越該通孔並延伸至該基板,或坐落於該通孔之周緣內。因此,該蓋體可接觸該基板或與該基板保持距離。在上述任一情況下,該蓋體均係從該導熱凸柱之頂部沿側面方向側向延伸而出。The cover may be formed by various deposition techniques, including electroplating, electroless plating, evaporation, and sputtering, before, during, or after the bonding of the bonding layer, including forming a single layer by electroplating, electroless plating, evaporation, and sputtering. Or multilayer structure. The cover It can be made of the same metal material as the thermal conductive stud or the same metal material as the top of the thermal conductive stud adjacent to the cover. In addition, the cover may span the through hole and extend to the substrate or be located within the periphery of the through hole. Thus, the cover can contact or be spaced from the substrate. In either case, the cover extends laterally from the top of the thermally conductive stud in the lateral direction.

該黏著層可在該散熱座與該基板之間提供堅固之機械性連結。例如,該黏著層可自該導熱凸柱側向延伸並越過該導線到達該組體之外圍邊緣,該黏著層可填滿該散熱座與該基板間之空間,且該黏著層可為一具有均勻分佈之結合線之無孔洞結構。該黏著層亦可吸收該散熱座與該基板間因熱膨脹所產生之不匹配現象。此外,該黏著層可為一低成本電介質,且不需具備高導熱性。再者,該黏著層不易脫層。The adhesive layer provides a strong mechanical bond between the heat sink and the substrate. For example, the adhesive layer may extend laterally from the heat conducting stud and pass the wire to the peripheral edge of the group. The adhesive layer may fill the space between the heat sink and the substrate, and the adhesive layer may have A non-porous structure of a uniformly distributed bond line. The adhesive layer can also absorb the mismatch caused by thermal expansion between the heat sink and the substrate. In addition, the adhesive layer can be a low cost dielectric and does not require high thermal conductivity. Furthermore, the adhesive layer is not easily delaminated.

吾人可調整該黏著層之厚度,使該黏著層實質填滿該等缺口,並使幾乎所有黏著劑在固化及/或研磨後均位於結構體內。例如,理想之膠片厚度可由試誤法決定。同樣地,吾人亦可調整該介電層之厚度以達此一效果。We can adjust the thickness of the adhesive layer so that the adhesive layer substantially fills the gaps and allows almost all of the adhesive to be located within the structure after curing and/or grinding. For example, the ideal film thickness can be determined by trial and error. Similarly, we can also adjust the thickness of the dielectric layer to achieve this effect.

該基板可為一低成本之層壓結構,且不需具備高導熱性。此外,該基板可包含單一導電層或複數層導電層。再者,該基板可包含該導電層或由該導電層組成。The substrate can be a low cost laminate structure and does not require high thermal conductivity. Additionally, the substrate can comprise a single conductive layer or a plurality of conductive layers. Furthermore, the substrate may comprise or consist of the conductive layer.

該導電層可單獨設置於該黏著層上。例如,可先在該導電層上形成該等通孔,然後將該導電層設置於該黏著層上,使該導電層接觸該黏著層,並朝該向上方向外露,在 此同時,該導熱凸柱及該訊號凸柱則延伸進入該等通孔,並透過該等通孔朝該向上方向外露。在此例中,該導電層之厚度可為100至200微米,例如125微米,此厚度一方面夠厚,故搬運時不致彎曲晃動,一方面則夠薄,故不需過度蝕刻即可形成圖案。The conductive layer can be separately disposed on the adhesive layer. For example, the through holes may be formed on the conductive layer, and then the conductive layer is disposed on the adhesive layer, so that the conductive layer contacts the adhesive layer and is exposed in the upward direction. At the same time, the heat conducting stud and the signal stud extend into the through holes and are exposed through the through holes in the upward direction. In this case, the conductive layer may have a thickness of 100 to 200 micrometers, for example, 125 micrometers. The thickness is thick enough on the one hand, so that it does not bend when transported, and is thin enough on the one hand, so that the pattern can be formed without excessive etching. .

亦可將該導電層與該介電層一同設置於該黏著層上。例如,可先將該導電層設置於該介電層上,然後在該導電層及該介電層上形成該等通孔,接著將該導電層及該介電層設置於該黏著層上,使該導電層朝該向上方向外露,並使該介電層接觸且介於該導電層與該黏著層之間,因而將該導電層與該黏著層隔開,在此同時,該導熱凸柱及該訊號凸柱則延伸進入該等通孔,並透過該等通孔朝該向上方向外露。在此例中,該導電層之厚度可為10至50微米,例如30微米,此厚度一方面夠厚,足以提供可靠之訊號傳導,一方面則夠薄,可降低重量及成本。此外,該介電層恆為該導熱板之一部分。The conductive layer may also be disposed on the adhesive layer together with the dielectric layer. For example, the conductive layer may be disposed on the dielectric layer, and then the via holes are formed on the conductive layer and the dielectric layer, and then the conductive layer and the dielectric layer are disposed on the adhesive layer. Exposing the conductive layer toward the upward direction and contacting the dielectric layer between the conductive layer and the adhesive layer, thereby separating the conductive layer from the adhesive layer, and at the same time, the thermally conductive stud And the signal studs extend into the through holes and are exposed through the through holes in the upward direction. In this case, the conductive layer may have a thickness of 10 to 50 microns, such as 30 microns, which is thick enough on the one hand to provide reliable signal transmission and, on the other hand, thin enough to reduce weight and cost. Furthermore, the dielectric layer is always part of the heat conducting plate.

亦可將該導電層與一載體同時設置於該黏著層上。例如,可先利用一薄膜將該導電層黏附於一諸如雙定向聚對苯二甲酸乙二酯膠膜(Mylar)之載體,然後僅在該導電層而非該載體上形成該等通孔,接著將該導電層及該載體設置於該黏著層上,使該載體覆蓋該導電層,且朝該向上方向外露,並使該薄膜接觸且介於該載體與該導電層之間,至於該導電層則接觸且介於該薄膜與該黏著層之間,在此同時,該導熱凸柱及該訊號凸柱則對準該等通孔,並由該載 體從上方覆蓋。該黏著層固化後,可利用紫外光分解該薄膜,以便將該載體從該導電層上剝除,從而使該導電層朝該向上方向外露,之後便可研磨及圖案化該導電層以形成該導線。在此例中,該導電層之厚度可為10至50微米,例如30微米,此厚度一方面夠厚,足以提供可靠之訊號傳導,一方面則夠薄,可降低重量及成本;至於該載體之厚度可為300至500微米,此厚度一方面夠厚,故搬運時不致彎曲晃動,一方面又夠薄,有助於減少重量及成本。該載體僅為一暫時固定物,並非永久屬於該導熱板之一部分。The conductive layer may also be disposed on the adhesive layer simultaneously with a carrier. For example, the conductive layer may be adhered to a carrier such as a bi-directional polyethylene terephthalate film (Mylar) by using a film, and then the via holes are formed only on the conductive layer instead of the carrier. And then the conductive layer and the carrier are disposed on the adhesive layer, the carrier covers the conductive layer, and is exposed in the upward direction, and the film is contacted and interposed between the carrier and the conductive layer, as for the conductive The layer is in contact with and between the film and the adhesive layer, and at the same time, the heat conducting stud and the signal stud are aligned with the through holes, and the load is The body is covered from above. After the adhesive layer is cured, the film may be decomposed by ultraviolet light to strip the carrier from the conductive layer, thereby exposing the conductive layer toward the upward direction, and then the conductive layer may be ground and patterned to form the conductive layer. wire. In this case, the conductive layer may have a thickness of 10 to 50 micrometers, for example 30 micrometers, which is thick enough on the one hand to provide reliable signal transmission, and on the other hand thin enough to reduce weight and cost; The thickness can be 300 to 500 micrometers, and the thickness is thick enough on the one hand, so that it does not bend and shake when transported, and is thin enough on the one hand to help reduce weight and cost. The carrier is only a temporary fixture and is not permanently part of the heat conducting plate.

位於該介電層上之該焊墊與該路由線可在該基板尚未或已然設置於該黏著層上時,以多種沉積技術製成,包括以電鍍、無電鍍被覆、蒸發及噴濺等技術形成單層或多層結構。例如,可在該基板尚未設置於該黏著層上時、或在該基板已藉由該黏著層而黏附於該導熱凸柱及該訊號凸柱與該基座後,於該基板上形成該導電層之圖案。The pad and the routing line on the dielectric layer can be fabricated by various deposition techniques, including electroplating, electroless plating, evaporation, and sputtering, when the substrate is not yet or already disposed on the adhesive layer. A single layer or a multilayer structure is formed. For example, the conductive layer may be formed on the substrate when the substrate is not disposed on the adhesive layer, or after the substrate has been adhered to the heat conductive stud and the signal stud and the base by the adhesive layer.

The wire can be used as a signal layer, a power layer or a ground layer depending on the purpose of the corresponding semiconductor component pads. The wire may also comprise various conductive metals such as copper, gold, nickel, silver, palladium, tin, mixtures thereof, and alloys thereof. The ideal composition depends both on the nature of the externally connected medium and on the design and reliability considerations. In addition, those skilled in the art will appreciate that the copper used in the semiconductor wafer package may be pure copper, but is typically a copper-based alloy such as copper-zirconium (99.9% copper), copper-silver- Phosphorus-magnesium (99.7% copper) and copper-tin-iron-phosphorus (99.7% copper) to improve mechanical properties such as tensile strength and ductility.

在一般情況下,最好在前述研磨後之表面上設有該蓋體、介電層、防焊綠漆、被覆接點及第二導電層,但於某些實施例中則可省略之。例如,若該開口及通孔係以衝孔而非鑽孔之方式產生,因而使該導熱凸柱頂部之形狀及尺寸均與該半導體元件之熱接觸表面相配適,則可省略該蓋體與該第二導電層以降低成本。同樣地,可省略該介電層以降低成本。In general, it is preferable to provide the cover, the dielectric layer, the solder resist green lacquer, the coated contact and the second conductive layer on the surface after the grinding, but in some embodiments, it may be omitted. For example, if the opening and the through hole are formed by punching instead of drilling, so that the shape and size of the top of the heat conducting stud are matched with the thermal contact surface of the semiconductor element, the cover and the cover may be omitted. The second conductive layer reduces cost. As such, the dielectric layer can be omitted to reduce cost.

例如,可在一金屬板上蝕刻出多條凹槽以形成該基座、多個導熱凸柱與多個訊號凸柱;而後將一具有對應該等導熱凸柱及該等訊號凸柱之開口的未固化黏著層設置於該基座上,俾使每一導熱凸柱及訊號凸柱均延伸貫穿一對應開口;然後將一基板(其具有單一導電層、單一介電層以及對應該等導熱凸柱及該等訊號凸柱之通孔)設置於該黏著層上,俾使每一凸柱均延伸貫穿一對應開口並進入一對應通孔;而後利用壓台將該基座與該基板彼此靠合,迫使該黏著層進入該等通孔內介於該等導熱凸柱及該等訊號凸柱與該基板間之缺口;然後固化該黏著層,繼而研磨該等導熱凸柱、該等訊號凸柱、該黏著層及該第一導電層以形成一頂面;然後將第二導電層被覆設置於該等導熱凸柱、該等訊號凸柱、該黏著層及該第一導電層上;接著蝕刻該第一與第二導電層以形成多組分別對應該等訊號凸柱之焊墊及 路由線,蝕刻該第二導電層以形成多個分別對應該等導熱凸柱之蓋體,並蝕刻該基座以形成多個對應該等導熱凸柱之基座以及多個對應該等訊號凸柱之端子;而後將頂部防焊綠漆設於結構體上,並使該頂部防焊綠漆產生圖案,藉以曝露該等焊墊及該等蓋體,另將底部防焊綠漆設於該結構體上,使該底部防焊綠漆產生圖案,藉以曝露該等基座及該等端子;而後以被覆接點對該等基座、該等焊墊、該等端子及該等蓋體進行表面處理;最後於該等導熱板外圍邊緣之適當位置切割或劈裂該基板、該黏著層及該等防焊綠漆,俾使個別之導熱板彼此分離。For example, a plurality of grooves may be etched on a metal plate to form the pedestal, the plurality of thermally conductive studs and the plurality of signal studs; and then an opening having a corresponding thermally conductive stud and the signal studs An uncured adhesive layer is disposed on the pedestal such that each of the thermal conductive posts and the signal studs extend through a corresponding opening; and then a substrate (having a single conductive layer, a single dielectric layer, and corresponding heat conduction) The through holes of the studs and the signal studs are disposed on the adhesive layer, so that each of the studs extends through a corresponding opening and enters a corresponding through hole; and then the base and the substrate are mutually connected by the pressing table Relying the adhesive layer into the through holes, the gap between the heat conducting studs and the signal studs and the substrate; then curing the adhesive layer, and then grinding the thermally conductive studs, the signals a pillar, the adhesive layer and the first conductive layer to form a top surface; and then a second conductive layer is disposed on the heat conducting studs, the signal bumps, the adhesive layer and the first conductive layer; Then etching the first and second conductive layers to form Group respectively correspond to the signal pads and the like of the boss and Routing a second conductive layer to form a plurality of caps respectively corresponding to the thermally conductive studs, and etching the pedestal to form a plurality of pedestals corresponding to the thermally conductive studs and a plurality of corresponding signal bumps a terminal of the column; and then the top solder resist green paint is disposed on the structure, and the top solder resist green paint is patterned to expose the solder pads and the cover body, and the bottom solder resist green paint is disposed on the bottom Structurally, the bottom solder resist green lacquer is patterned to expose the pedestals and the terminals; and then the pedestals, the pads, the terminals, and the covers are covered by the covered contacts Surface treatment; finally cutting or cleaving the substrate, the adhesive layer and the solder resist green paint at appropriate positions on the peripheral edge of the heat conducting plates to separate the individual heat conducting plates from each other.

該半導體晶片組體之作業格式可為單一組體或多個組體,取決於製造設計。例如,可單獨製造單一組體。或者,可同時批次製造多個組體,之後再將各導熱板一一分離。同樣地,亦可將多個半導體元件電性連結、熱連結及機械性連結至批次量產中之每一導熱板。The operational format of the semiconductor wafer package can be a single group or a plurality of groups, depending on the manufacturing design. For example, a single set can be manufactured separately. Alternatively, a plurality of groups can be manufactured in batches at the same time, and then the heat conducting plates are separated one by one. Similarly, a plurality of semiconductor elements may be electrically connected, thermally coupled, and mechanically coupled to each of the heat conducting plates in mass production.

例如,可將多個錫膏部分分別沉積於多個焊墊及蓋體上,而後將多個LED封裝體分別置於該等錫膏部分上,接著同時加熱該等錫膏部分以使其迴焊、硬化並形成多個焊接點,之後再將各導熱板一一分離。For example, a plurality of solder paste portions may be separately deposited on the plurality of pads and the cover, and then the plurality of LED packages are respectively placed on the solder paste portions, and then the solder paste portions are simultaneously heated to be returned. Welding, hardening and forming a plurality of solder joints, and then separating the heat conducting plates one by one.

在另一範例中係將多個固晶材料分別沉積於多個蓋體上,而後將多枚晶片分別放置於該等固晶材料上,之後再同時加熱該等固晶材料以使其硬化並形成多個固晶,而後將該等晶片打線接合至對應之焊墊,接著在該等晶片與打線上形成對應之封裝材料,最後再將各導熱板一一分離。In another example, a plurality of solid crystal materials are separately deposited on a plurality of covers, and then a plurality of wafers are respectively placed on the solid crystal materials, and then the solid crystal materials are simultaneously heated to harden them. A plurality of solid crystals are formed, and then the wafers are wire bonded to the corresponding pads, and then corresponding packaging materials are formed on the wafers and the wires, and finally the heat conducting plates are separated one by one.

吾人可透過單一步驟或多道步驟使各導熱板彼此分離。例如,可將多個導熱板批次製成一平板,接著將多個半導體元件設置於該平板上,然後再將該平板所構成之多個半導體晶片組體一一分離。或者,可將多個導熱板批次製成一平板,而後將該平板所構成之多個導熱板分切為多個導熱板條,接著將多個半導體元件分別設置於該等導熱板條上,最後再將各導熱板條所構成之多個半導體晶片組體分離為個體。此外,在分割導熱板時可利用機械切割、雷射切割、分劈或其他適用技術。We can separate the heat conducting plates from each other in a single step or in multiple steps. For example, a plurality of heat conducting plates can be batched into a flat plate, and then a plurality of semiconductor elements are disposed on the flat plate, and then the plurality of semiconductor wafer assemblies formed by the flat plates are separated one by one. Alternatively, a plurality of heat conducting plates can be batched into a flat plate, and then the plurality of heat conducting plates formed by the flat plate are slit into a plurality of heat conducting strips, and then a plurality of semiconductor elements are respectively disposed on the heat conducting strips. Finally, the plurality of semiconductor wafer assemblies formed by the heat conducting strips are separated into individual parts. In addition, mechanical cutting, laser cutting, bifurcation or other suitable techniques may be utilized in splitting the thermally conductive plates.

在本文中,「鄰接」一語意指元件係一體成形(形成單一個體)或相互接觸(彼此無間隔或未隔開)。例如,該導熱凸柱係鄰接該基座,此與形成該導熱凸柱時採用增添法或削減法無關。As used herein, the term "adjacent" means that the elements are integrally formed (forming a single individual) or in contact with one another (with or without separation from one another). For example, the thermally conductive stud is adjacent to the pedestal, which is independent of the addition or reduction method when forming the thermally conductive stud.

「重疊」一語意指位於上方並延伸於一下方元件之周緣內。「重疊」包含延伸於該周緣之內、外或坐落於該周緣內。例如,該半導體元件係重疊於該導熱凸柱,乃因一假想垂直線可同時貫穿該半導體元件與該導熱凸柱,不論該半導體元件與該導熱凸柱間是否存在有另一同為該假想垂直線貫穿之元件(如該蓋體),且亦不論是否有另一假想垂直線僅貫穿該半導體元件而未貫穿該導熱凸柱(亦即位於該導熱凸柱之周緣外)。同樣地,該黏著層係重疊於該基座並被該焊墊重疊,而該基座則被該導熱凸柱重疊。同樣地,該導熱凸柱係重疊於該基座且位於其周緣內。此外,「重疊」與「位於上方」同義,「被重疊」則與「位於下方」同義。The term "overlapping" means located above and extending within the perimeter of a lower element. "Overlap" includes extending within, outside of, or within the circumference of the circumference. For example, the semiconductor component is overlapped with the thermally conductive stud because an imaginary vertical line can simultaneously penetrate the semiconductor component and the thermally conductive stud, regardless of whether there is another imaginary vertical between the semiconductor component and the thermally conductive stud. The element through which the wire runs, such as the cover, and whether or not another imaginary vertical line extends only through the semiconductor component does not extend through the thermally conductive stud (ie, outside the periphery of the thermally conductive stud). Similarly, the adhesive layer is overlaid on the pedestal and overlapped by the pads, and the pedestal is overlapped by the thermally conductive studs. Likewise, the thermally conductive stud is superposed on the base and is located within its circumference. In addition, "overlap" is synonymous with "below" and "overlap" is synonymous with "below".

「接觸」一語意指直接接觸。例如,該介電層接觸該焊墊但並未接觸該導熱凸柱或該基座。The term "contact" means direct contact. For example, the dielectric layer contacts the pad but does not contact the thermally conductive stud or the pedestal.

For example, the pedestal covers the thermally conductive stud from below, but the thermally conductive stud does not cover the pedestal from above.

「層」字包含設有圖案或未設圖案之層體。例如,當該基板設置於該黏著層上時,該導電層可為該介電層上一空白無圖案之平板;而當該半導體元件設置於該散熱座上之後,該導電層可為該介電層上一具有間隔導線之電路圖案。此外,「層」可包含複數疊合層。The "layer" word contains a layer with or without a pattern. For example, when the substrate is disposed on the adhesive layer, the conductive layer may be a blank unpatterned flat plate on the dielectric layer; and after the semiconductor component is disposed on the heat sink, the conductive layer may be the dielectric layer A circuit pattern having spaced wires on the electrical layer. In addition, a "layer" may comprise a plurality of superposed layers.

「焊墊」一語與該導線搭配使用時係指一用於連接及/或接合外部連接媒介(如焊料或打線)之連結區域,而該外部連接媒介則可將該導線電性連結至該半導體元件。The term "pad" as used in connection with the conductor means a connection area for connecting and/or engaging an external connection medium (such as solder or wire), and the external connection medium electrically connects the wire to the Semiconductor component.

「蓋體」一語與該散熱座搭配使用時係指一用於連接及/或接合外部連接媒介(如焊料或導熱黏著劑)之接觸區域,而該外部連接媒介則可將該散熱座熱連結至該半導體元件。The term "cover" when used in conjunction with the heat sink refers to a contact area for connecting and/or bonding an external connection medium (such as solder or a thermally conductive adhesive), and the external connection medium can heat the heat sink. Connected to the semiconductor component.

「開口」與「通孔」等語同指貫穿孔洞。例如,當該導熱凸柱***該黏著層之該開口時,該導熱凸柱係沿向上方向曝露於該黏著層。同樣地,當該導熱凸柱***該基板 之該通孔時,該導熱凸柱係沿向上方向曝露於該基板。The words "opening" and "through hole" refer to the through hole. For example, when the thermally conductive stud is inserted into the opening of the adhesive layer, the thermally conductive stud is exposed to the adhesive layer in an upward direction. Similarly, when the thermally conductive stud is inserted into the substrate In the through hole, the thermally conductive stud is exposed to the substrate in an upward direction.

「***」一語意指元件間之相對移動。例如,「將該導熱凸柱***該通孔中」包含:該導熱凸柱固定不動而由該基板向該基座移動;該基板固定不動而由該導熱凸柱向該基板移動;以及該導熱凸柱與該基板兩者彼此靠合。又例如,「將該導熱凸柱***(或延伸至)該通孔內」包含:該導熱凸柱貫穿(穿入並穿出)該通孔;以及該導熱凸柱***但未貫穿(穿入但未穿出)該通孔。The term "insertion" means the relative movement between components. For example, "inserting the thermal conductive stud into the through hole" includes: the thermally conductive stud is fixed and moved by the substrate toward the base; the substrate is fixed and moved by the thermally conductive stud to the substrate; and the thermal conduction Both the stud and the substrate abut each other. For another example, “inserting (or extending into) the through-hole of the heat-conducting stud includes: the heat-conducting stud penetrating (passing in and penetrating) the through-hole; and the thermally-conductive stud is inserted but not penetrated (penetrated) But did not wear out the through hole.

「彼此靠合」一語亦指元件間之相對移動。例如,「該基座與該基板彼此靠合」包含:該基座固定不動而由該基板移往該基座;該基板固定不動而由該基座向該基板移動;以及該基座與該基板相互靠近。The phrase "together with each other" also refers to the relative movement between components. For example, "the pedestal and the substrate abut each other" includes: the pedestal is fixed and moved from the substrate to the pedestal; the substrate is fixed and moved by the pedestal to the substrate; and the pedestal and the pedestal The substrates are close to each other.

「對準」一語意指元件間之相對位置。例如,當該黏著層已設置於該基座上、該基板已設置於該黏著層上、該導熱凸柱已***並對準該開口,且該通孔已對準該開口時,無論該導熱凸柱係***該通孔或位於該通孔下方且與其保持距離,該導熱凸柱均已對準該通孔。The term "aligned" means the relative position between components. For example, when the adhesive layer is disposed on the pedestal, the substrate is disposed on the adhesive layer, the thermal conductive stud has been inserted and aligned with the opening, and the through hole has been aligned with the opening, regardless of the thermal conduction. The stud is inserted into or located below the through hole, and the thermally conductive stud is aligned with the through hole.

「設置於」一語包含與單一或多個支撐元件間之接觸與非接觸。例如,該半導體元件係設置於該散熱座上,不論該半導體元件係實際接觸該散熱座或係與該散熱座以一固晶材料相隔。同樣地,該半導體元件係設置於該散熱座上,不論該半導體元件係僅設置於該散熱座上或係同時設置於該散熱座與該基板上。The term "set in" encompasses contact and non-contact with a single or multiple support elements. For example, the semiconductor component is disposed on the heat sink, whether the semiconductor component is actually in contact with the heat sink or is separated from the heat sink by a solid crystal material. Similarly, the semiconductor component is disposed on the heat sink, and the semiconductor component is disposed only on the heat sink or on the heat sink and the substrate.

「黏著層…於該缺口之中」一語意指位於該缺口中之 該黏著層。例如,「黏著層在該缺口中延伸跨越該介電層」意指該缺口內之該黏著層延伸跨越該介電層。同樣地,「黏著層於該缺口之中接觸且介於該導熱凸柱與該介電層之間」意指該缺口中之該黏著層接觸且介於該缺口內側壁之該導熱凸柱與該缺口外側壁之該介電層之間。The phrase "adhesive layer...in the gap" means located in the gap The adhesive layer.

For example, the thermally conductive stud extends above the pedestal while abutting, overlapping the pedestal and projecting from the pedestal. Similarly, the thermally conductive stud extends above the dielectric layer even if the thermally conductive stud does not abut or overlap the dielectric layer.

「下方」一語意指向下延伸,且包含鄰接與非鄰接元件以及重疊與非重疊元件。例如,該基座係延伸於該導熱凸柱下方,鄰接該導熱凸柱,被該導熱凸柱重疊,並自該導熱凸柱突伸而出。同樣地,該導熱凸柱係延伸於該介電層下方,即便該導熱凸柱並未鄰接該介電層或被該介電層重疊。The word "below" is intended to mean a downward extension and includes contiguous and non-contiguous elements as well as overlapping and non-overlapping elements. For example, the pedestal extends below the thermally conductive stud, adjacent to the thermally conductive stud, and is overlapped by the thermally conductive stud and protrudes from the thermally conductive stud. Similarly, the thermally conductive stud extends below the dielectric layer even if the thermally conductive stud is not adjacent to or overlapped by the dielectric layer.

所謂「向上」及「向下」之垂直方向並非取決於該半導體晶片組體(或該導熱板)之定向,凡熟悉此項技藝之人士可輕易瞭解其實際所指之方向。例如,該導熱凸柱係沿向上方向垂直延伸於該基座上方,而該黏著層則沿向下方向垂直延伸於該焊墊下方,此與該組體是否倒置及/或是否係設置於一散熱裝置上無關。同樣地,該基座係沿一側向平面自該導熱凸柱「側向」延伸而出,此與該組體是否倒置、旋轉或傾斜無關。因此,該向上及向下方向係彼此相 對且垂直於側面方向,此外,側向對齊之元件係在一垂直於該向上與向下方向之側向平面上彼此共平面。The vertical direction of "upward" and "downward" does not depend on the orientation of the semiconductor wafer package (or the thermal plate), and those skilled in the art can easily understand the actual direction. For example, the thermally conductive stud extends vertically above the pedestal in an upward direction, and the adhesive layer extends vertically below the solder pad in a downward direction, whether the set is inverted and/or is disposed at a It has nothing to do with the heat sink. Similarly, the pedestal extends laterally from the thermally conductive stud along a lateral plane, regardless of whether the set is inverted, rotated or tilted. Therefore, the upward and downward directions are related to each other. Paired and perpendicular to the side direction, in addition, the laterally aligned elements are coplanar with one another in a lateral plane perpendicular to the upward and downward directions.

本發明之半導體晶片組體具有多項優點。該組體之可靠度高、價格平實且極適合量產。該組體尤其適用於易產生高熱且需優異散熱效果方可有效及可靠運作之高功率半導體元件,例如LED封裝體、大型半導體晶片以及多個同時使用之小型半導體元件(例如以陣列方式排列之多枚小形半導體晶片)。The semiconductor wafer package of the present invention has a number of advantages.
