Description

探針結構 Probe structure 【相關申請案】【Related application】

本發明係為台灣專利申請案第107106387號(申請日:2018年02月26日)之分割案,該申請案之完整內容納入為本發明專利說明書的一部分以供參照。 The present invention is a divisional case of Taiwan Patent Application No. 107106387 (application date: February 26, 2018), and the entire contents of the application are incorporated as part of the patent specification of the invention for reference.

本發明涉及一種探針結構,特別是涉及一種應用於晶圓探針卡的探針結構。 The invention relates to a probe structure, in particular to a probe structure applied to a wafer probe card.

首先,現有技術的懸臂式探針卡主要是通過人工的方式將探針逐一焊接在印刷電路板上,同時,通過一黏著物(例如環氧樹脂)將探針固定。例如,TW I447397所揭露的“探針卡”專利案,其探針33即是利用包含有環氧樹脂的固持部36而固定在電路板34上。 First of all, the cantilever probe card of the prior art mainly solders the probes one by one on the printed circuit board manually, and at the same time, the probes are fixed by an adhesive (such as epoxy resin). For example, in the "probe card" patent case disclosed by TW I447397, the probe 33 is fixed on the circuit board 34 by using the holding portion 36 containing epoxy resin.

但是,上述現有技術中,當環氧樹脂硬化後,會使得懸臂式探針卡變得不易維修。換句話說,當其中一根探針損壞時,現有技術的懸臂式探針卡並無法單獨替換該損壞的探針,必須將整組懸臂式探針卡進行更換。 However, in the above-mentioned prior art, when the epoxy resin is hardened, the cantilever probe card becomes difficult to maintain. In other words, when one of the probes is damaged, the prior art cantilever probe card cannot replace the damaged probe alone, and the entire group of cantilever probe cards must be replaced.

再者,現有技術的懸臂式探針卡的焊線方式,須要通過密集的線材以進行扇出(Fan-out)製程,且因人工焊線須要較寬廣的空間,所以傳輸路徑較長。因此,會導致訊號傳輸品質較差。進一步地,現有技術的懸臂式探針卡的探針線徑較寬,故在佈線上除了橫向排列之外,仍必須進行縱向堆疊。但是,當針數多或間距小時,將導致探針安排的困難度增加。 In addition, the conventional wire bonding method of the cantilever probe card requires a dense wire for the fan-out process, and since the manual bonding wire requires a wider space, the transmission path is longer. Therefore, the signal transmission quality will be poor. Further, the cantilever probe card of the prior art has a wide probe wire diameter, so in addition to the horizontal arrangement on the wiring, the vertical stacking must still be performed. However, when the number of needles is large or the pitch is small, it will increase the difficulty of probe arrangement.

進一步來說,現有的懸臂式探針卡結構,傳輸路徑太長,阻 抗無法控制,傳輸品質較不佳。同時,電源訊號會因為傳輸路徑過長,且探針截面積過窄,其電感特性將使電源阻抗隨頻率上升,造成電壓下降而使得測試良率不佳。 Furthermore, in the existing cantilever probe card structure, the transmission path is too long, The resistance cannot be controlled and the transmission quality is poor. At the same time, the power signal will be too long and the cross-sectional area of the probe is too narrow. Its inductive characteristics will cause the power supply impedance to increase with frequency, resulting in a voltage drop and poor test yield.

本發明所要解決的技術問題在於,針對現有技術的不足提供一種探針結構,能有效地改善懸臂式探針不易維修之特性,同時,能改善傳輸品質並降低維護成本。同時,能降低探針結構的傳輸路徑中電感的影響。 The technical problem to be solved by the present invention is to provide a probe structure for the shortcomings of the prior art, which can effectively improve the characteristics of the cantilever probe which is not easy to repair, and at the same time, can improve the transmission quality and reduce the maintenance cost. At the same time, the influence of inductance in the transmission path of the probe structure can be reduced.

為了解決上述的技術問題,本發明所採用的其中一技術方案是,提供一種探針結構,其包括一第一基部、一第二基部、一連接部以及一接觸部。所述第一基部包括一第一接觸段以及一連接於所述第一接觸段的第一連接段,其中,所述第一接觸段具有一第一抵靠部以及一連接於所述第一抵靠部的第一側端。所述第二基部包括一第二接觸段、一第二連接段以及一電性連接於所述第二接觸段與所述第二連接段之間的被動元件,其中,所述第二接觸段具有一第二抵靠部以及一連接於所述第二抵靠部的第二側端。所述第一基部的所述第一連接段以及所述第二基部的所述第二連接段連接於所述連接部。所述接觸部連接於所述連接部。 In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a probe structure including a first base portion, a second base portion, a connecting portion, and a contact portion. The first base portion includes a first contact section and a first connection section connected to the first contact section, wherein the first contact section has a first abutment portion and a connection to the first The first side end of the abutment. The second base portion includes a second contact section, a second connection section and a passive element electrically connected between the second contact section and the second connection section, wherein the second contact section It has a second abutting portion and a second side end connected to the second abutting portion. The first connection section of the first base and the second connection section of the second base are connected to the connection section. The contact portion is connected to the connection portion.

本發明的其中一有益效果在於,本發明實施例所提供的探針結構,其能利用“所述第二基部包括一第二接觸段、一第二連接段以及一電性連接於所述第二接觸段與所述第二連接段之間的被動元件”的技術方案,而降低探針結構的傳輸路徑中電感的影響。 One of the beneficial effects of the present invention is that the probe structure provided by the embodiment of the present invention can utilize "the second base includes a second contact section, a second connection section and an electrical connection to the first "The passive component between the two contact sections and the second connection section" reduces the influence of inductance in the transmission path of the probe structure.

The probe structure 1 may include a first base 11, a second base 12, a connecting portion 13 and a contact portion 14. The first base 11 may include a first contact section 111 and a first connection section 112 connected to the first contact section 111. The second base 12 may include a second contact section 121, a second connection section 122 and a passive element C electrically connected between the second contact section 121 and the second connection section 122. The first connection section 112 of the first base 11 and the second connection section 122 of the second base 12 may be connected to the connection section 13. In addition, the contact portion 14 may be connected to the connection portion 13. Preferably, the distance between the second base portion 12 and the contact portion 14 is closer than the distance between the first base portion 11 and the contact portion 14. Further, according to the embodiment of the invention, the probe structure 1 is a cantilever probe structure 1.

承上述,請復參閱圖1及圖2所示,第一接觸段111可具有一第一抵靠部1111以及一連接於第一抵靠部1111的第一側端1112。第二接觸段121可具有一第二抵靠部1211以及一連接於第二抵靠部1211的第二側端1212,且接觸部14可具有一接觸側端141。以本發明實施例而言,第一接觸段111及第二接觸段121可以為探針結構1的針尾,以用於與轉接介面板(例如圖12的基板2)的接觸端(例如圖12的導電結構21)相接。另外,探針結構1的 接觸部14的接觸側端141可呈尖頭針狀,以劃破待測物的錫球表面的氧化層,然而,在其他實施方式中,探針結構1的接觸側端141也可為一平面,本發明不以此為限。 According to the above, please refer to FIGS. 1 and 2 again. The first contact section 111 may have a first abutting portion 1111 and a first side end 1112 connected to the first abutting portion 1111. The second contact section 121 may have a second abutting portion 1211 and a second side end 1212 connected to the second abutting portion 1211, and the contact portion 14 may have a contact side end 141.

However, in other embodiments, the contact-side end 141 of the probe structure 1 may also be a The plane is not limited to this invention.

接著,請復參閱圖1至圖3所示,優選地,以本發明實施例而言,被動元件C可為一電容,舉例來說,被動元件C可為多層陶瓷電容器或薄膜平型板電容器,然本發明不以此為限。此外,可利用微機電系統(Microelectromechanical Systems,MEMS)技術將被動元件C嵌入第二基部12的第二接觸段121與第二連接段122之間。進一步來說,第一基部11與第二基部12可分別用於接收不同的訊號,以通過接觸部14而饋入待測物中。藉此,通過被動元件C的諧振點,可用來調整不同頻率的電源阻抗,避免電源訊號的電壓下降。舉例來說,當距離待測物的傳輸路徑越短時,路徑中的電感則越小,因此可使用容值較小的電容,且相對應的諧振點在較高頻段的位置,即可壓制較高頻段的電源阻抗,最終可應用於較高頻段的測試方案,以符合未來需求。同時,通過被動元件C的設置,可就近的提供待測物所需的電源,避免路徑中電感的干擾,以改善電源完整性(power integrity,PI)。 Next, please refer to FIG. 1 to FIG. 3 again. Preferably, in terms of the embodiment of the present invention, the passive element C may be a capacitor. For example, the passive element C may be a multilayer ceramic capacitor or a film flat plate capacitor However, the present invention is not limited to this. In addition, the passive element C may be embedded between the second contact section 121 and the second connection section 122 of the second base 12 using microelectromechanical systems (MEMS) technology. Further, the first base 11 and the second base 12 can be used to receive different signals to feed into the object through the contact 14. In this way, the resonance point of the passive element C can be used to adjust the impedance of the power supply at different frequencies to avoid the voltage drop of the power supply signal. For example, when the transmission path from the DUT is shorter, the inductance in the path is smaller, so a capacitor with a smaller capacitance can be used, and the corresponding resonance point is located at a higher frequency band, which can be suppressed The power supply impedance of the higher frequency band can be finally applied to the test program of the higher frequency band to meet future requirements. At the same time, through the arrangement of the passive component C, the power required by the object under test can be provided nearby to avoid the interference of the inductance in the path to improve the power integrity (PI).

承上述,請復參閱圖1及圖2所示,第一基部11的第一連接段112連接於連接部13,第二基部12的第二連接段122連接於連接部13,以使得第一連接段112能相對於連接部13形成一第一裸露表面1121,且使得第二連接段122能相對於連接部13形成一第二裸露表面1221。也就是說,由於第一連接段112的橫截面形狀及第二連接段122的橫截面形狀能與連接部13的橫截面形狀在尺 寸上有著截然不同的特性,因此,第一連接段112及第二連接段122能分別相對於連接部13形成一第一裸露表面1121及第二裸露表面1221。藉此,第一連接段112與連接部13之間可具有一段差,且第二連接段122與連接部13之間可具有一段差,而使得第一連接段112及第二連接段122相對於連接部13在整體結構上呈非連續的設置。更進一步來說,第一連接段112與連接部13間的連接處為一轉折處,且該轉折處可具有一第一裸露表面1121。此外,第二連接段122與連接部13間的連接處為一轉折處,且該轉折處可具有一第二裸露表面1221。 Following the above, please refer to FIG. 1 and FIG. 2 again, the first connecting section 112 of the first base 11 is connected to the connecting section 13, and the second connecting section 122 of the second base 12 is connected to the connecting section 13, so that the first The connecting section 112 can form a first exposed surface 1121 relative to the connecting portion 13, and the second connecting section 122 can form a second exposed surface 1221 relative to the connecting portion 13. That is to say, since the cross-sectional shape of the first connecting section 112 and the cross-sectional shape of the second connecting section 122 can be There are very different characteristics in the size, therefore, the first connection section 112 and the second connection section 122 can form a first exposed surface 1121 and a second exposed surface 1221 relative to the connection portion 13, respectively. Thereby, there may be a step difference between the first connection section 112 and the connection portion 13, and there may be a step difference between the second connection section 122 and the connection portion 13, so that the first connection section 112 and the second connection section 122 are opposite The connecting portion 13 is provided discontinuously in the overall structure. Furthermore, the connection between the first connection section 112 and the connection portion 13 is a turning point, and the turning point may have a first exposed surface 1121. In addition, the connection between the second connection section 122 and the connection portion 13 is a turning point, and the turning point may have a second exposed surface 1221.

In any cross section of the connecting portion 13, the connecting portion 13 may have a first side (not labeled in the figure) and a second side (not labeled in the figure) The first side may have a first width F1, the second side may have a second width F2, and the size of the first width F1 may be smaller than the size of the second width F2. That is, the sheet structure may have a first width F1 and a second width F2, and the size of the first width F1 is smaller than the size of the second width F2. Preferably, the ratio of the first width F1 and the second width F2 may be between 0.2 and 0.5. For example, the first width F1 may be 0.1 millimeter (mm) and the second width F2 may be 2 mm to Between 5 mm, the invention is not limited to this. Further, since the direction of the contact portion 14 is in the Z direction, the length direction (extending direction) of the second side is toward the third direction (negative Z direction), and the connecting portion 13 is the first One side is in contact with the first connection section 112 and the second connection section 122, therefore, although the size of the first width F1 is smaller than the size of the second width F2, the contact side end 141 of the contact portion 14 can still be kept in contact with the test Physical power.

接著,請復參閱圖10所示,第一接觸段111的一最大外徑W1寸可小於第一貫孔31的第一孔徑H1的尺寸,且第二接觸段121的一最大外徑W2的尺寸可小於第一貫孔31的第一孔徑H1的尺寸,以使第一接觸段111及第二接觸段121能通過第一貫孔31。此外,第一接觸段111的一最大外徑W1尺寸可小於第二貫孔41的第二孔徑H2的尺寸,且第二接觸段121的一最大外徑W2尺寸可小於第二貫孔41的第二孔徑H2的尺寸,以使第一接觸段111及第二接觸段121能通過第二貫孔41。再者,第一接觸段111 可電性連接於多個導電結構21中的其中一個,且第二接觸段121可電性連接於多個導電結構21中的另外一個。 Next, please refer to FIG. 10 again, a maximum outer diameter W1 inch of the first contact section 111 may be smaller than the size of the first aperture H1 of the first through hole 31, and a maximum outer diameter W2 of the second contact section 121 The size may be smaller than the size of the first aperture H1 of the first through hole 31 so that the first contact section 111 and the second contact section 121 can pass through the first through hole 31. In addition, a maximum outer diameter W1 of the first contact section 111 may be smaller than the second aperture H2 of the second through hole 41, and a maximum outer diameter W2 of the second contact section 121 may be smaller than the size of the second through hole 41 The size of the second aperture H2 is such that the first contact segment 111 and the second contact segment 121 can pass through the second through hole 41. Furthermore, the first contact section 111 It can be electrically connected to one of the plurality of conductive structures 21, and the second contact section 121 can be electrically connected to the other one of the plurality of conductive structures 21.

接著,請參閱圖11所示,使用者可通過移動第一板體3及第二板體4的相對位置,以使得第一板體3及第二板體4相互錯位。即,可將第一板體3朝向X方向移動,且將第二板體4朝向負X方向。藉此,探針結構1的第一抵靠部1111及第二抵靠部1211可分別抵接於相對應的頂抵部32,以達到定位探針結構1的效果。 Next, referring to FIG. 11, the user can move the relative positions of the first plate body 3 and the second plate body 4 so that the first plate body 3 and the second plate body 4 are misaligned with each other. That is, the first plate body 3 can be moved toward the X direction, and the second plate body 4 can be directed toward the negative X direction. Thereby, the first abutting portion 1111 and the second abutting portion 1211 of the probe structure 1 can respectively abut against the corresponding abutment portions 32 to achieve the effect of positioning the probe structure 1.

接著,請參閱圖12所示,探針組件M優選還可進一步包括一固定件5(舉例來說,固定件5可例如但不限於為一螺絲),固定件5可設置在基板2、第一板體3以及第二板體4上,以使探針結構1的第一抵靠部1111及第二抵靠部1211分別抵接於相對應的頂抵部32。換句話說,固定件5可用於定位探針結構1與基板2、第一板體3以及第二板體4的相對位置。另外,值得說明的是,由於探針結構1分別是通過第一抵靠部1111及第二抵靠部1211而抵接於相對應的頂抵部32,以使得探針結構1進行定位。藉此,當其中一根探針結構1受損故障時,可通過移動第一板體3及第二板體4而將故障的探針結構1進行替換。 Next, referring to FIG. 12, the probe assembly M preferably further includes a fixing member 5 (for example, the fixing member 5 may be, for example but not limited to, a screw), and the fixing member 5 may be disposed on the substrate 2, the first On the one plate body 3 and the second plate body 4, the first abutting portion 1111 and the second abutting portion 1211 of the probe structure 1 respectively abut against the corresponding abutting portions 32. In other words, the fixing member 5 can be used to locate the relative positions of the probe structure 1 and the substrate 2, the first plate body 3 and the second plate body 4. In addition, it is worth noting that the probe structure 1 abuts the corresponding abutment portion 32 through the first abutting portion 1111 and the second abutting portion 1211, respectively, so that the probe structure 1 is positioned. In this way, when one of the probe structures 1 is damaged and fails, the failed probe structure 1 can be replaced by moving the first plate body 3 and the second plate body 4.

值得說明的是,由於第一連接段112及第二連接段122的橫截面形狀可呈一矩形狀的外型,而連接部13的橫截面形狀可呈片狀(薄片狀的矩形狀)的外型。因此,在設置第二板體4後,在使得第一接觸段111、第一連接段112(部分的第一連接段112或是全部的第一連接段112)、第二接觸段121以及第二連接段122(部分的第二連接段122或是全部的第二連接段122)都埋設在第二板體4與基板2之間後,可以避免兩個探針結構1所分別具有的第一基部11與第二基部12之間的干涉。 It is worth noting that, since the cross-sectional shapes of the first connecting section 112 and the second connecting section 122 can be a rectangular shape, the cross-sectional shape of the connecting portion 13 can be a sheet (a thin rectangular shape) Appearance. Therefore, after the second plate 4 is provided, the first contact section 111, the first connection section 112 (part of the first connection section 112 or all of the first connection section 112), the second contact section 121 and the first After the second connection sections 122 (part of the second connection sections 122 or all of the second connection sections 122) are buried between the second board 4 and the substrate 2, the first sections of the two probe structures 1 can be avoided Interference between a base 11 and a second base 12.

接著,請參閱圖13及圖14所示,圖13為本發明實施例的探針結構的另一種實施方式的立體示意圖,圖14為本發明實施例的探針結構的使用狀態示意圖。由圖13與圖1的比較可知,圖13 的探針結構1’圖1的探針結構1最大的差別在於:圖1的探針結構1主要可用於提供電源,而圖13的探針結構1’要可用於提供訊號。因此,圖13的探針結構1’不具有第二基部12。另外,須說明的是,圖13的探針結構1’第二基部12之外皆與圖1的探針結構1相仿,具體細節在此不再贅述。 Next, please refer to FIGS. 13 and 14. FIG. 13 is a perspective schematic view of another embodiment of the probe structure according to the embodiment of the present invention. FIG. 14 is a schematic view of the use state of the probe structure according to the embodiment of the present invention. From the comparison between Figure 13 and Figure 1, we can see that Figure 13 The biggest difference between the probe structure 1'of FIG. 1 and the probe structure 1 of FIG. 1 is that the probe structure 1 of FIG. 1 is mainly used to provide power, and the probe structure 1'of FIG. 13 is to be used to provide signals. Therefore, the probe structure 1'of FIG. 13 does not have the second base portion 12. In addition, it should be noted that the probe structure 1'of FIG. 13 is similar to the probe structure 1 of FIG. 1 except for the second base portion 12, and specific details are not repeated here.

承上述,請復參閱圖13及圖14所示,圖14為多個探針結構(1、1’)的俯視圖。由圖14所示的實施方式可以了解,探針結構(1、1’)可依探針卡的量測陣列設計而佈置,此外,多個探針結構(1、1’)可具有彼此相異的構造(舉例來說,多個探針結構(1、1’)中的至少其中兩個具有相異的長度)。也就是說,可以依據需求而調整各個探針結構(1、1’)的排列角度。此外,探針結構(1、1’)的接觸側端141可電性連接於待測物接點N。 In view of the above, please refer to FIGS. 13 and 14 again. FIG. 14 is a plan view of a plurality of probe structures (1, 1'). It can be understood from the embodiment shown in FIG. 14 that the probe structures (1, 1') can be arranged according to the measurement array design of the probe card, and in addition, a plurality of probe structures (1, 1') can have phases with each other Different configurations (for example, at least two of the plurality of probe structures (1, 1') have different lengths). That is, the arrangement angle of each probe structure (1, 1') can be adjusted according to requirements. In addition, the contact side end 141 of the probe structure (1, 1') can be electrically connected to the contact N of the object under test.

[實施例的有益效果] [Beneficial effect of embodiment]

本發明的其中一有益效果在於,本發明實施例所提供的探針結構1,其能利用“第二基部12包括一第二接觸段121、一第二連接段122以及一電性連接於第二接觸段121與第二連接段122之間的被動元件C”的技術方案,而降低探針結構的傳輸路徑中電感的影響,以改善電源完整性。 One of the beneficial effects of the present invention is that the probe structure 1 provided by the embodiment of the present invention can utilize the “second base 12 includes a second contact section 121, a second connection section 122, and an electrical connection to the The technical solution of the passive component C” between the two contact sections 121 and the second connection section 122 reduces the influence of inductance in the transmission path of the probe structure to improve power integrity.

另外,本發明實施例還能夠通過“第一接觸段111具有一第一抵靠部1111”以及“第二接觸段121具有一第二抵靠部1211”的技術方案,能使得探針結構1可以單獨抽換,以形成一可替換式的探針結構1,而降低維護成本。同時,相較於現有的懸臂式探針結構,還能縮短現有懸臂式探針阻抗不連續之傳輸路徑,而改善傳輸品質的訊號完整性(Signal Integrity,SI)。 In addition, the embodiments of the present invention can also make the probe structure 1 through the technical solutions of "the first contact section 111 has a first abutting portion 1111" and "the second contact section 121 has a second abutting portion 1211" It can be swapped separately to form a replaceable probe structure 1 and reduce maintenance costs. At the same time, compared with the existing cantilever probe structure, it can also shorten the transmission path of the existing cantilever probe impedance discontinuous, and improve the signal integrity (SI) of the transmission quality.

再者,由於本發明實施例所提供的探針結構1為一懸臂式探針結構1,因此,所以針尖是向外引導的,所以可以利用多組不同的第一板體3、第二板體4及固定件5而將探針結構1固定在基板 2上。進一步來說,可利用不同長度的探針結構1而降低細間距(fine pitch)的加工困難度。此外,由於連接部13及/或接觸部14的橫截面形狀可呈片狀(薄片狀的矩形狀)的外型(第一連接段112及第二連接段122為一柱狀結構,連接部13為一片狀結構,且柱狀結構與片狀結構的形狀不同),因此,不僅可對應微間距的需求,還可提供所需的支撐力量強度。 Furthermore, since the probe structure 1 provided in the embodiment of the present invention is a cantilever probe structure 1, the needle tip is guided outward, so multiple sets of different first plate bodies 3 and second plates can be used Body 4 and fixture 5 to fix the probe structure 1 to the substrate 2 on. Furthermore, the probe structures 1 of different lengths can be used to reduce the processing difficulty of fine pitch. In addition, since the cross-sectional shape of the connecting portion 13 and/or the contact portion 14 may be in the shape of a sheet (a thin rectangular shape) (the first connecting section 112 and the second connecting section 122 are a columnar structure, the connecting section 13 is a sheet-like structure, and the shape of the columnar structure and the sheet-like structure are different.) Therefore, it can not only meet the needs of micro-spacing, but also provide the required supporting strength.

進一步來說,探針結構1的第一抵靠部1111及第二抵靠部1211可分別抵接於相對應的第一板體3的頂抵部32,因此,能將探針結構1定位在基板2上,以使得探針結構1的第一接觸段111及第二接觸段121電性連接於基板2上的導電結構21。 Further, the first abutting portion 1111 and the second abutting portion 1211 of the probe structure 1 can respectively abut against the corresponding abutment portions 32 of the first plate body 3, therefore, the probe structure 1 can be positioned On the substrate 2, the first contact section 111 and the second contact section 121 of the probe structure 1 are electrically connected to the conductive structure 21 on the substrate 2.
