Description

本発明は半導体パッケージに関し、特に、半導体集積回路の全般のパッケージとして使用可能な微細配線パッケージに関する。   The present invention relates to a semiconductor package, and more particularly to a fine wiring package that can be used as a general package of a semiconductor integrated circuit.

通常、微細配線パッケージ上には、単体又は複数の能動素子又は受動素子が封止樹脂等によって固定されている。そして個々の能動素子又は受動素子上には、配線層と絶縁樹脂層が積層されている。   Usually, a single active element or a plurality of active elements or passive elements are fixed on a fine wiring package by a sealing resin or the like. A wiring layer and an insulating resin layer are laminated on each active element or passive element.

このような、単体又は複数の能動素子又は受動素子を搭載した微細配線パッケージを製造する場合において、支持体を用い、この支持体上に接着剤層を介して各素子を搭載し、樹脂で各素子を封止した後、配線層と絶縁樹脂層とを積層し、しかる後に、支持体を除去して、微細配線パッケージを完成させる製造方法がある。   In the case of manufacturing such a fine wiring package on which a single active element or a plurality of active elements or passive elements are mounted, a support is used, and each element is mounted on the support via an adhesive layer. There is a manufacturing method in which after a device is sealed, a wiring layer and an insulating resin layer are laminated, and then a support is removed to complete a fine wiring package.

上記のように支持体を用いた微細配線パッケージの製造方法において、複数の能動素子又は受動素子を支持体に搭載する場合に、各素子の端子面を同一面に揃えて封止することが必要となる場合がある。かかる場合において、従来の一般的な微細配線パッケージの製造方法を次に説明する。   In the method of manufacturing a fine wiring package using a support as described above, when a plurality of active elements or passive elements are mounted on the support, it is necessary to seal the terminal surfaces of the elements on the same surface. It may become. In such a case, a conventional method of manufacturing a general fine wiring package will be described next.

図１（ａ）〜図１（ｆ）は、複数の能動素子又は受動素子等の電子部品を支持体に搭載し、樹脂封止して、パッケージに組み込む場合の従来技術であって、各能動素子又は受動素子の端子側を基準として同一面に揃える場合の例を示す。   FIG. 1A to FIG. 1F are prior arts in the case where electronic parts such as a plurality of active elements or passive elements are mounted on a support, sealed with resin, and incorporated in a package. The example in the case of aligning on the same surface on the basis of the terminal side of an element or a passive element is shown.

まず、図１（ａ）において、支持体１０上に接着剤２０を介して受動素子１２、能動素子１４、１６等を搭載する。受動素子１２、能動素子１４、１６の端子１２ａ、１４ａ、１６ａは、支持体１０の上面で位置合わせされる。   First, in FIG. 1A, the passive element 12, the active elements 14 and 16, etc. are mounted on the support 10 via the adhesive 20. The terminals 12 a, 14 a and 16 a of the passive element 12 and the active elements 14 and 16 are aligned on the upper surface of the support 10.

次に、図１（ｂ）において、支持体１０上の受動素子１２、能動素子１４、１６等の部品は、樹脂２２で封止する。樹脂２２の注入時の圧力により、部品が位置ずれを起こしたり、樹脂２２が混入することにより端子１２ａ、１４ａ、１６ａが汚染されたりする虞がある。   Next, in FIG. 1B, components such as the passive element 12 and the active elements 14 and 16 on the support 10 are sealed with a resin 22. There is a possibility that the components may be displaced due to the pressure when the resin 22 is injected, or that the terminals 12a, 14a, and 16a may be contaminated when the resin 22 is mixed.

次に、図１（ｃ）において、樹脂２２が硬化収縮した後、支持体１０が剥離される。封止樹脂の硬化及び収縮により、樹脂２２の表面に凹凸が発生したり、支持体１０の剥離による樹脂２２の表面の反りが生じたりする虞がある。   Next, in FIG. 1C, after the resin 22 is cured and contracted, the support 10 is peeled off. Due to the curing and shrinkage of the sealing resin, the surface of the resin 22 may be uneven, or the surface of the resin 22 may be warped due to the peeling of the support 10.

次に、図１（ｄ）において、図１（ａ）〜図１（ｃ）とは上下を逆に、受動素子１２、能動素子１４、１６の端子１２ａ、１４ａ、１６ａ側を上側として、パッケージの表面に樹脂層２４を形成し、各端子に接続するビア２６を形成し、樹脂層２４上には、ビア２６に接続する配線パターン（配線層）２８を形成する。そして、図１（ｅ）に示すように、樹脂層２４及び配線層２８を交互に積層し、パッケージを多層に形成する。   Next, in FIG. 1 (d), the packages 12a, 14a, and 16a side of the passive element 12 and the active elements 14 and 16 are turned upside down from those of FIGS. 1 (a) to 1 (c). A resin layer 24 is formed on the surface, vias 26 connected to the respective terminals are formed, and wiring patterns (wiring layers) 28 connected to the vias 26 are formed on the resin layer 24. And as shown in FIG.1 (e), the resin layer 24 and the wiring layer 28 are laminated | stacked alternately, and a package is formed in a multilayer.

図１（ｅ）において、樹脂層２４及び配線層２８を交互に積層すると共に、各層間の接続用のビア２６を形成して多層に構成した後、パッケージの最表面に、ソルダレジスト層３０等を形成し、最上の配線層２８に接続する外部接続用の外部端子３２を形成し、パッケージを完成する。   In FIG. 1E, the resin layers 24 and the wiring layers 28 are alternately laminated, and vias 26 for connection between the respective layers are formed to form a multilayer structure. Then, a solder resist layer 30 or the like is formed on the outermost surface of the package. The external connection 32 for external connection connected to the uppermost wiring layer 28 is formed to complete the package.

図１（ｆ）にこのようにして完成された微細配線パッケージを示す。各受動素子１２、能動素子１４、１６の端子１２ａ、１４ａ、１６ａの表面は、支持体１０の表面により規定される所定の面Ａに整合されることとなる。なお、受動素子１２、能動素子１４、１６の中に放熱部品が含まれる場合は、このような放熱性のある電子部品（素子）について、その背面における封止樹脂２２を剥離し、電子部品の背面を露出させる（図示せず）。そして、封止樹脂２２を剥離した電子部品の背面には必要によりヒートシンク（図示せず）等を接続して放熱性を良好なものとする。   FIG. 1F shows the fine wiring package thus completed. The surfaces of the terminals 12 a, 14 a and 16 a of the passive elements 12 and the active elements 14 and 16 are aligned with a predetermined surface A defined by the surface of the support 10. In addition, when the heat dissipation component is included in the passive element 12 and the active elements 14 and 16, the sealing resin 22 on the back surface of the electronic component (element) having such a heat dissipation property is peeled off. The back side is exposed (not shown). Then, if necessary, a heat sink (not shown) or the like is connected to the back surface of the electronic component from which the sealing resin 22 has been peeled to improve heat dissipation.

上記のような従来の微細配線パッケージの製造方法において、一般に次のような問題がある。支持体と素子との間の仮接着を、後の工程で支持体を素子を含むパッケージから剥離する必要があることを考慮して、予め弱くしておくと、素子を支持体に仮接着した後に樹脂を封止する際、端子と支持体との間に樹脂が混入して端子が汚染されたり、樹脂の注入時の圧力によって素子の位置が支持体に対して所定の位置からずれることがある。   The above-described conventional method for manufacturing a fine wiring package generally has the following problems. Considering that it is necessary to peel the support from the package containing the element in a later step, the temporary attachment between the support and the element is temporarily bonded to the support. When sealing the resin later, the resin may be mixed between the terminal and the support to contaminate the terminal, or the position of the element may deviate from the predetermined position with respect to the support due to the pressure when the resin is injected. is there.

逆に支持体と素子との間の仮接着を強くすると、接着剤そのものが端子に付着する。封止樹脂の硬化収縮等により端子面に凹凸が発生し、端子面が平坦にならない。支持体をパッケージから剥離するため、パッケージに反りが発生し、端子面が平坦にならない。素子の背面に放熱部品を付加する場合は、当該背面における封止樹脂を研磨等により除去して素子の背面をあらためて露出させる必要がある。   On the contrary, when the temporary adhesion between the support and the element is strengthened, the adhesive itself adheres to the terminal. Unevenness occurs on the terminal surface due to hardening shrinkage of the sealing resin, and the terminal surface does not become flat. Since the support is peeled from the package, the package is warped and the terminal surface is not flat. When a heat dissipation component is added to the back surface of the element, it is necessary to remove the sealing resin on the back surface by polishing or the like to expose the back surface of the element again.

図２（ａ）〜図２（ｅ）は、複数の能動素子又は受動素子を支持体に搭載し、樹脂封止して、パッケージに組み込む場合の他の従来技術であって、各素子の背面側を基準として同一面に揃える場合の例を示す。   2 (a) to 2 (e) are other prior arts in which a plurality of active elements or passive elements are mounted on a support, resin-sealed, and incorporated into a package. The example in the case of aligning on the same plane with the side as a reference is shown.

まず、図２（ａ）において、支持体１０上に接着剤２０を介して受動素子１２、能動素子１４、１６等を搭載する。受動素子１２、能動素子１４、１６の背面側が、支持体１０の上面で位置合わせされる。   First, in FIG. 2A, the passive element 12, the active elements 14, 16 and the like are mounted on the support 10 via the adhesive 20. The back surfaces of the passive element 12 and the active elements 14 and 16 are aligned with the upper surface of the support 10.

次に、図２（ｂ）において、支持体１０上の受動素子１２、能動素子１４、１６等の電子部品は、樹脂２２で封止される。樹脂２２の注入時の圧力により、部品が位置ずれを起こしたり、樹脂２２が混入することにより端子１２ａ、１４ａ、１６ａが汚染されたりする虞がある。   Next, in FIG. 2B, electronic components such as the passive element 12 and the active elements 14 and 16 on the support 10 are sealed with a resin 22. There is a possibility that the components may be displaced due to the pressure when the resin 22 is injected, or that the terminals 12a, 14a, and 16a may be contaminated when the resin 22 is mixed.

次に、図２（ｃ）において、封止した樹脂層２２にビア２６を形成するとともに、樹脂層２２上に配線層２８を形成する。支持体１０上の受動素子１２、能動素子１４、１６等の部品は、背面側が、支持体１０の上面で位置合わせされるので、各素子の端子に接続させるためのビア２６を形成するにあたっては、各素子間で導通孔の深さが異なり、導通孔の形成が困難である。   Next, in FIG. 2C, a via 26 is formed in the sealed resin layer 22, and a wiring layer 28 is formed on the resin layer 22. Since components such as the passive element 12 and the active elements 14 and 16 on the support 10 are aligned on the upper surface of the support 10 on the back side, the vias 26 for connecting to the terminals of each element are formed. The depth of the conduction hole is different between the elements, and it is difficult to form the conduction hole.

図２（ｄ）において、樹脂層２２上にはビア２６に接続する配線パターン（配線層）２８を形成する。そして、樹脂層２４及び配線層２８を交互に積層すると共に、各層間の接続用のビア２６を形成して多層に構成する。パッケージの最表面には、ソルダレジスト層３０等を形成し、最上の配線層２８に接続する外部接続用の外部端子３２を形成し、パッケージを完成する。一方で、このようなパッケージが完成した後、支持体１０をパッケージから剥離する。   In FIG. 2D, a wiring pattern (wiring layer) 28 connected to the via 26 is formed on the resin layer 22. Then, the resin layers 24 and the wiring layers 28 are alternately laminated, and connection vias 26 between the respective layers are formed to form a multilayer structure. A solder resist layer 30 and the like are formed on the outermost surface of the package, and external terminals 32 for external connection connected to the uppermost wiring layer 28 are formed, thereby completing the package. On the other hand, after such a package is completed, the support 10 is peeled from the package.

図２（ｅ）において、受動素子１２、能動素子１４、１６の背面が封止樹脂２２から露出した微細配線パッケージが完成する。各部品の背面が封止樹脂２２から露出しているので、部品の背面に必要によりヒートシンク等（図示せず）を接続する場合には、好都合である。一方、受動素子１２、能動素子１４、１６の電極端子１２ａ、１４ａ、１６ａの表面の高さは、各電子部品の高さの相違等によりＢ１、Ｂ２、Ｂ３等と不揃いとなる。これにより、受動素子１２、能動素子１４、１６等の電子部品の電極端子１２ａ、１４ａ、１６ａを配線層８に接続するビア２６の高さも電子部品毎に不揃いとなってしまう。   In FIG. 2E, the fine wiring package in which the back surfaces of the passive element 12 and the active elements 14 and 16 are exposed from the sealing resin 22 is completed. Since the back surface of each component is exposed from the sealing resin 22, it is convenient when a heat sink or the like (not shown) is connected to the back surface of the component as necessary. On the other hand, the heights of the surfaces of the electrode terminals 12a, 14a and 16a of the passive element 12 and the active elements 14 and 16 are inconsistent with B1, B2, B3, etc. due to differences in the height of each electronic component. As a result, the heights of the vias 26 that connect the electrode terminals 12a, 14a, 16a of the electronic components such as the passive element 12, the active elements 14, 16 and the like to the wiring layer 8 are also uneven for each electronic component.

なお、本発明に関連する先行技術として、米国特許第６，１５４，３６６号明細書がある。これによると、微細電子部品パッケージの製造方法において、少なくとも端子を有する能動面、背面及び側面を有する微細電子部品素子を準備し、この素子の能動面に絶縁層の第１面を接合し、絶縁層の第２面に配線層を形成すると共に、この配線層の一部を絶縁層を貫通して素子の端子に接続し、素子側を樹脂で封止すると共に、封止樹脂の第１面を絶縁層の底面に隣接するように構成し、前記絶縁層及び配線層に湿気防止用のバリア層を形成している。このような構成により、配線層の金属の腐食を防止すると共に、絶縁層の劣化を防止している。   As a prior art related to the present invention, there is US Pat. No. 6,154,366. According to this, in the method for manufacturing a microelectronic component package, a microelectronic component element having at least an active surface having terminals, a back surface and a side surface is prepared, and the first surface of the insulating layer is bonded to the active surface of the device to A wiring layer is formed on the second surface of the layer, a part of this wiring layer is connected to the terminal of the element through the insulating layer, the element side is sealed with resin, and the first surface of the sealing resin Is configured to be adjacent to the bottom surface of the insulating layer, and a barrier layer for preventing moisture is formed on the insulating layer and the wiring layer. With such a configuration, corrosion of the metal in the wiring layer is prevented and deterioration of the insulating layer is prevented.

上記のように、従来の微細配線パッケージの製造方法によると、後の工程において支持体を剥離することを考慮して、支持体と素子との仮接着を弱めに設定する必要があるが、仮接着の程度を弱くすることによって樹脂を封止する際端子と支持体との間に樹脂が混入して端子が汚染されたり、樹脂注入時の圧力により素子が位置ずれすることがある。逆に支持体と素子との仮接着を強めに設定すると、接着剤そのものが端子に付着する、封止樹脂の硬化収縮等により封止樹脂表面に凹凸が発生し、端子面が平坦にならない、支持体を剥離するため、反りが発生し、端子面が平坦にならない、等の問題がある。また、前記封止樹脂上に絶縁層を形成する際、前記封止樹脂から露出した前記電子部品の端子の高さ分だけ絶縁樹脂に凹凸が生じ、その後の配線形成で不具合が生じ、信頼性の良い配線を形成できなくなる、という問題がある。   As described above, according to the conventional method for manufacturing a fine wiring package, it is necessary to set the temporary adhesion between the support and the element weak in consideration of peeling the support in a later process. When the resin is sealed by weakening the degree of adhesion, the resin may be mixed between the terminal and the support to contaminate the terminal, or the element may be displaced due to pressure during resin injection. On the contrary, if the temporary adhesion between the support and the element is set to be strong, the adhesive itself adheres to the terminal, the sealing resin surface is uneven due to the curing shrinkage of the sealing resin, etc., and the terminal surface does not become flat, Since the support is peeled off, there is a problem that warpage occurs and the terminal surface does not become flat. In addition, when forming the insulating layer on the sealing resin, the insulating resin is uneven by the height of the terminal of the electronic component exposed from the sealing resin, resulting in problems in the subsequent wiring formation, reliability. There is a problem that a good wiring cannot be formed.

本発明は上記のような解決するもので、パッケージを構成する電子部品の端子面を均一な高さに設定することにより、各端子に接続する導通孔による端子と配線との電気的接続を容易にする共に、パッケージの製造工程の最後の段階まで、支持体に支持された状態でパッケージを形成して、各部の位置ずれ等を生じさせないような、微細配線に適したパッケージを得ることのできる製造方法及びそのようにして製造された微細配線パッケージのを提供することを課題とする。   The present invention solves the above, and by setting the terminal surfaces of the electronic components constituting the package to a uniform height, the electrical connection between the terminals and the wirings by the conduction holes connected to the respective terminals is facilitated. In addition, it is possible to obtain a package suitable for fine wiring that does not cause misalignment of each part by forming the package while being supported by the support until the last stage of the manufacturing process of the package. It is an object of the present invention to provide a manufacturing method and a fine wiring package manufactured as described above.

このような課題を達成するために、本発明によれば、一方の面に搭載した、各々複数の端子を有する高さの異なる複数の電子部品と、該電子部品の端子の表面を所定の平面上に揃えるように、前記複数の電子部品を、電極端子形成面が露出するように、且つ該電子部品の側面の一部を覆うように、封止すると共に、表面の高さを、前記電子部品の電極端子形成面と同じ又はやや低い程度とした封止樹脂と、該封止樹脂の背面に接し、前記電子部品の側面の一部及び背面を覆うように形成された接着剤層と、隣接する電子部品間を含む前記封止樹脂の表面上に形成した導体層と、前記封止樹脂上に形成され、前記電子部品の電極端子形成面及び電極端子、並びに前記導体層を覆うように設けた絶縁樹脂層と、前記絶縁樹脂層上に形成した、前記電子部品の端子に電気的に接続される配線層と、を積層して成ることを特徴とする微細配線パッケージが提供される。 In order to achieve such a problem, according to the present invention, a plurality of electronic components each having a plurality of terminals mounted on one surface and having different heights, and the surfaces of the terminals of the electronic components are arranged in a predetermined plane. The plurality of electronic components are sealed so that the electrode terminal formation surface is exposed and a part of the side surface of the electronic component is covered so that the surface of the plurality of electronic components is aligned. A sealing resin that is the same or slightly lower than the electrode terminal forming surface of the component, an adhesive layer that is in contact with the back surface of the sealing resin and covers a part of the side surface and the back surface of the electronic component, a conductor layer formed on the surface of the sealing resin containing between adjacent electronic components, formed on the sealing resin, the electronic component of the electrode terminal forming surface and the electrode terminals, and so as to cover the conductive layer The insulating resin layer provided, and the insulating resin layer formed on the insulating resin layer; Fine wiring package, characterized in that formed by laminating a wiring layer electrically connected to the child part of the terminal is provided.

上記の微細配線パッケージにおいて、前記配線層の一部はビアを介して前記導体層に接続されていることを特徴とする。また、前記導体層は、前記電子部品の電極端子の表面と略同一面であることを特徴とする。 In the above-mentioned fine wiring package, a part of the wiring layer characterized in that it is connected to the conductor layer through a via. Also, the conductor layer is characterized in that the the surface and substantially the same surface of the electronic component of the electrode terminals.

また、本発明によれば、一方の面に搭載した、各々複数の電極端子を有する高さの異なる複数の電子部品と、該電子部品の電極端子の表面を所定の平面上に揃えるように、前記複数の電子部品を、電極端子形成面及び背面が露出するように、且つ該電子部品の側面の一部を覆うように、封止する封止樹脂と、隣接する電子部品間を含む前記封止樹脂上に、前記複数の電子部品の電極端子形成面を露出し、且つ該電子部品の側面の一部を覆うように設け、且つ、表面を前記電子部品の電極端子の表面と略同一面とした補強板としての導電性樹脂と、前記導電性樹脂上に形成され、前記電子部品の電極端子形成面及び電極端子、並びに前記封止樹脂を覆うように設けた絶縁樹脂層と、前記電子部品及び前記封止樹脂の表面上に形成した、前記電子部品の電極端子に電気的に接続する配線層と、を含むことを特徴とする微細配線パッケージが提供される。 Further, according to the present invention, mounted on one surface, each a plurality of different heights plurality of electronic components having an electrode terminal, so as to align the surface of the electrode terminals of the electronic components on a predetermined plane, The plurality of electronic components including the sealing resin that seals between the adjacent electronic components and the sealing resin so that the electrode terminal forming surface and the back surface are exposed and part of the side surface of the electronic component is covered. On the stop resin, the electrode terminal forming surfaces of the plurality of electronic components are exposed so as to cover a part of the side surfaces of the electronic components , and the surface is substantially the same as the surface of the electrode terminals of the electronic components a conductive resin as a reinforcing plate and is formed on the conductive resin, the electrode terminal forming surface and the electrode terminals of the electronic component, and an insulating resin layer provided so as to cover the sealing resin, the electronic The electron formed on the surface of the component and the sealing resin Fine wiring package is provided which comprises a wiring layer electrically connected to the electrode terminals of the goods, the.

上記の微細配線パッケージにおいて、前記配線層の一部はビアを介して前記導電性樹脂（５０）に接続されていることを特徴とする。 In the above-mentioned fine wiring package, a part of the wiring layer characterized in that it is connected to the conductive resin through a via (50).

本発明では、単数又は複数の電子部品の端子側を第１の接着剤層により第１の支持体の表面に仮固定し、電子部品の背面側を第２の接着剤層を有する第２の支持体で固定しているので、たとえ各電子部品の高さが不揃いであったとしても、各電子部品の端子が同一面に整合される。よって、端子と配線層との間の距離（深さ）が均一となり、導通孔による端子と配線との電気的な接続が比較的容易となる。また、配線層が完全に形成されるまで、パッケージが第２の支持体により保持されているので、製造時におけるパッケージの反りが大幅に縮小される。   In the present invention, the terminal side of one or a plurality of electronic components is temporarily fixed to the surface of the first support by the first adhesive layer, and the second side having the second adhesive layer on the back side of the electronic components. Since it is fixed by the support, even if the heights of the electronic components are not uniform, the terminals of the electronic components are aligned on the same surface. Therefore, the distance (depth) between the terminal and the wiring layer becomes uniform, and the electrical connection between the terminal and the wiring through the conduction hole becomes relatively easy. Further, since the package is held by the second support until the wiring layer is completely formed, the warpage of the package during manufacturing is greatly reduced.

また、本発明では、樹脂封止構造を採用したので、強度が向上し、この樹脂封止構造をコアとして配線層等の形成することが可能となる。更に、電子部品の端子面を平坦な同一面に成し得るため、微細配線の形成が可能となる。   Further, in the present invention, since the resin sealing structure is adopted, the strength is improved, and it becomes possible to form a wiring layer or the like using this resin sealing structure as a core. Furthermore, since the terminal surface of the electronic component can be formed on the same flat surface, it is possible to form fine wiring.

電子部品を樹脂封止した後、封止した樹脂層の表面に、電子部品の端子と略同一高さとなるように、導体補強層を形成した場合は、この補強層によって、封止樹脂の凹凸を吸収し、端子面の平坦化に寄与することとなる。また、導体補強層を電源層やグランド層として利用することができ、パッケージの電気的な特性を向上させることができる。更に、導体補強層を放熱層をとして利用することにより、パッケージに放熱効果を持たせることもできる。   After the electronic component is resin-sealed, when the conductor reinforcing layer is formed on the surface of the sealed resin layer so as to be approximately the same height as the terminals of the electronic component, the unevenness of the sealing resin is caused by this reinforcing layer. This will contribute to the flattening of the terminal surface. Further, the conductor reinforcing layer can be used as a power supply layer or a ground layer, and the electrical characteristics of the package can be improved. Further, by using the conductor reinforcing layer as a heat dissipation layer, the package can have a heat dissipation effect.

以下、添付図面を参照して本発明の実施の形態について詳細に説明する。
図３（ａ）〜図３（ｄ）、図４（ａ）〜図４（ｅ）及び図５（ａ）及び（ｂ）は、本発明の微細配線パッケージの製造方法の実施形態を示す。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
3 (a) to 3 (d), 4 (a) to 4 (e), 5 (a) and 5 (b) show an embodiment of the method for manufacturing a fine wiring package of the present invention.

各受動素子１２や能動素子１４、１６等の電子部品は、それぞれ、平坦な一方の面（第一の面）に複数の電極端子１２ａ、１４ａ、１６ａを有し、背面である他方の面（第二の面）も第一の面と平行な平坦面に形成されている。各電子部品の電極端子１２ａ、１４ａ、１６ａの表面も部品毎に一定の平面上に位置するように形成されている。   The electronic components such as the passive elements 12 and the active elements 14 and 16 each have a plurality of electrode terminals 12a, 14a, and 16a on one flat surface (first surface), and the other surface (the back surface). The second surface) is also formed on a flat surface parallel to the first surface. The surfaces of the electrode terminals 12a, 14a, and 16a of each electronic component are also formed so as to be positioned on a certain plane for each component.

図３（ａ）において、第１の支持体１０上に接着剤層２０を介して受動素子１２、能動素子１４、１６等を搭載する。受動素子１２、能動素子１４、１６の電極端子１２ａ、１４ａ、１６ａは、支持体１０の上面で位置合わせされる。接着剤層２０は、各電子部品の電極端子１２ａ、１４ａ、１６ａの表面位置を揃えるために、極力薄いもの（例えば、数μｍ〜数十μｍ程度）であり、且つ硬いものであることが好適である。また、接着剤層２０の接着強度としては、やや弱く、且つ電極端子１２ａ、１４ａ、１６ａの表面を汚染しない材質であるのが好ましい。このような接着剤層２０として、例えば、日東電工株式会社製のＴＲＭテープ、又は同社製のリバアルファ（登録商標）等を使用することができる。   In FIG. 3A, the passive element 12, the active elements 14, 16, etc. are mounted on the first support 10 via the adhesive layer 20. The electrode terminals 12 a, 14 a and 16 a of the passive element 12 and the active elements 14 and 16 are aligned on the upper surface of the support 10. The adhesive layer 20 is preferably as thin as possible (for example, about several μm to several tens of μm) and hard to align the surface positions of the electrode terminals 12a, 14a, and 16a of each electronic component. It is. The adhesive strength of the adhesive layer 20 is preferably a material that is slightly weak and does not contaminate the surfaces of the electrode terminals 12a, 14a, and 16a. As such an adhesive layer 20, for example, a TRM tape manufactured by Nitto Denko Corporation or Riva Alpha (registered trademark) manufactured by the same company can be used.

次に、図３（ｂ）において、一方の面に接着剤層４２を有する第２の支持体４０を、接着剤層４２が第１の支持体１０上の電子部品の電極端子１２ａ、１４ａ、１６ａの反対側である電子部品の背面に圧着するように配置する。ここで接着剤層４２は、各受動素子１２や能動素子１４、１６等の電子部品の厚さ、即ち電子部品の背面の高さの差異を吸収するために、ある程度厚いものが好ましい（例えば厚さが数十μｍ〜数百μｍ程度）。接着剤層４２はまた、部品に圧着する時点では、半液化状（常温又は加熱して）で接着力はや強いものが好ましい。また、紫外線（ＵＶ）の適用又は加熱等によりで剥離可能なものが好ましい。 Next, in FIG. 3 (b), the second support 40, the electronic components of the electrode terminal 12a of the adhesive layer 42 on the first support 10 having an adhesive layer 42 on one surface, 14a, It arrange | positions so that it may crimp | bond to the back surface of the electronic component which is the other side of 16a. Here, the adhesive layer 42 is preferably thick to some extent in order to absorb the difference in the thickness of the electronic components such as the passive elements 12 and the active elements 14 and 16, that is, the height of the back surface of the electronic components (for example, the thickness). Is about several tens of micrometers to several hundreds of micrometers). The adhesive layer 42 is preferably semi-liquefied (at room temperature or heated) and has a slightly strong adhesive force when it is pressure-bonded to the part. Moreover, what can be peeled off by application of ultraviolet rays (UV) or heating is preferred.

次に、図３（ｃ）において、第１の支持体１０を、パッケージである、受動素子１２や能動素子１４、１６等の電極端子１２ａ、１４ａ、１６ａから剥離する。この場合において、接着剤層２０は弱く且つ薄いものであるので、ＵＶ照射又は加熱等により容易に剥離することができる。このようにして、第１の支持体１０を剥離したパッケージを図３（ｄ）に示す。図３（ｄ）においては、受動素子１２や能動素子１４、１６等の電極端子１２ａ、１４ａ、１６ａがパッケージの上側となるようにパッケージを反転させ、以後の工程を行う。   Next, in FIG.3 (c), the 1st support body 10 is peeled from electrode terminals 12a, 14a, and 16a, such as the passive element 12 and the active elements 14 and 16, which are packages. In this case, since the adhesive layer 20 is weak and thin, it can be easily peeled off by UV irradiation or heating. The package from which the first support 10 is peeled in this way is shown in FIG. In FIG. 3D, the package is inverted so that the electrode terminals 12a, 14a, 16a such as the passive element 12 and the active elements 14, 16 are on the upper side of the package, and the subsequent processes are performed.

次に、図４（ａ）において、第２の支持体１０上の受動素子１２、能動素子１４、１６等の部品を、樹脂２２で封止する。この場合において、封止する樹脂２２の高さは、電子部品の上面と同じか又はやや低い程度とする。なお、封止に使用する樹脂２２の仕様は、液状樹脂で充填性の良好なものであって、モールド材、アンダーフィル材、液状レジスト材等を使用する。また、硬化収縮性や熱膨張性が小さく、封止力が強いものが好ましい。また、硬化収縮後に配線層を形成するのに適したものを使用する。   Next, in FIG. 4A, components such as the passive element 12 and the active elements 14 and 16 on the second support 10 are sealed with a resin 22. In this case, the height of the resin 22 to be sealed is the same as or slightly lower than the upper surface of the electronic component. The specification of the resin 22 used for sealing is a liquid resin with good filling properties, and a mold material, an underfill material, a liquid resist material, or the like is used. Moreover, a thing with small hardening shrinkage property and thermal expansibility and strong sealing power is preferable. Further, a material suitable for forming a wiring layer after curing shrinkage is used.

次に、図４（ｂ）において、封止樹脂２２の表面に導体層４４を形成する。これにより、封止樹脂２２の表面が安定し、各電子部品１２、１４、１６の端子１２ａ、１４ａ、１６ａの位置が安定し且つ平坦化される。   Next, in FIG. 4B, a conductor layer 44 is formed on the surface of the sealing resin 22. Thereby, the surface of the sealing resin 22 is stabilized, and the positions of the terminals 12a, 14a, and 16a of the electronic components 12, 14, and 16 are stabilized and flattened.

次に、図４（ｃ）において、受動素子１２、能動素子１４、１６の端子１２ａ、１４ａ、１６ａ及び封止樹脂２２上に形成した導体層４４を覆うように、絶縁樹脂層２４を形成する。   Next, in FIG. 4C, the insulating resin layer 24 is formed so as to cover the conductive elements 44 formed on the passive elements 12, the terminals 12a, 14a, 16a of the active elements 14, 16 and the sealing resin 22. .

図４（ｄ）において、絶縁樹脂層２４に、各端子に接続するビア２６を貫通形成し、樹脂層２４上には、ビア２６に接続する配線パターン（配線層）２８を形成する。そして、図４（ｅ）に示すように、樹脂層２４及び配線層２８を交互に積層し、パッケージを多層に形成する。なお、配線層２８の一部はビア２６を介して導体層４４にも接続される。   In FIG. 4D, vias 26 connected to the respective terminals are formed through the insulating resin layer 24, and wiring patterns (wiring layers) 28 connected to the vias 26 are formed on the resin layer 24. Then, as shown in FIG. 4E, the resin layers 24 and the wiring layers 28 are alternately laminated to form a multilayer package. A part of the wiring layer 28 is also connected to the conductor layer 44 through the via 26.

図４（ｅ）において、樹脂層２４及び配線層２８を交互に積層すると共に、各層間の接続用のビア２６を形成して多層に構成した後、パッケージの最表面に、ソルダレジスト層３０等を形成し、最上の配線層２８に接続する外部接続用の外部端子３２を形成し、第２の支持体４０の上にパッケージが完成される。   In FIG. 4E, the resin layers 24 and the wiring layers 28 are alternately stacked, and vias 26 for connection between the respective layers are formed to form a multilayer structure. Then, a solder resist layer 30 or the like is formed on the outermost surface of the package. The external terminal 32 for external connection connected to the uppermost wiring layer 28 is formed, and the package is completed on the second support 40.

図５（ａ）において、第２の支持体４０をパッケージの接着剤層４２から剥離する。これにより、図５（ｂ）に示すような本発明における微細配線パッケージが完成する。なお、第２の支持体４０を剥離する場合において、接着剤層４２も共に剥離し、電子部品１２、１４、１６の背面が封止樹脂２２から露出するように形成しても良い。   In FIG. 5A, the second support 40 is peeled from the adhesive layer 42 of the package. Thereby, the fine wiring package according to the present invention as shown in FIG. 5B is completed. When the second support 40 is peeled off, the adhesive layer 42 may also be peeled off so that the back surfaces of the electronic components 12, 14, 16 are exposed from the sealing resin 22.

完成した微細配線パッケージを示す図５（ｂ）において、上述のように、導体層４４を追加したことにより、パッケージにおける電気的な特性を向上させることができる。例えば、導体層４４の一部４４ａと配線層２８の一部２８ｂを接地（ＧＮＤに接続）し、配線層２８の一部を信号層（Ｓｉｇｎａｌ）２８ａとして使用することにより、この信号層２８ａをＧＮＤ−ＧＮＤ層で絶縁樹脂層２４を介してサンドイッチ状に配置した、いわゆるストリップライン（ＳＬ）構造とすることができる。このようなＳＬ構造により、信号層２８ａの電気的な特性、特にクロストークノイズを低減させる効果が期待できる。 5 showing the completed fine wiring package (b), as described above, by adding the conductive material layer 44, thereby improving the electrical characteristics of the package. For example, by grounding the portion 28b of the part 44a and the wiring layer 28 of the electrically layer 44 (connected to GND), using a part of the wiring layer 28 as a signal layer (Signal) 28a, the signal layer 28a Can be formed as a so-called strip line (SL) structure in which a GND-GND layer is sandwiched between insulating resin layers 24. Such an SL structure can be expected to reduce the electrical characteristics of the signal layer 28a, particularly the crosstalk noise.

図６〜図９は本発明の微細配線パッケージの変形例であって、第２〜第４実施形態に係る微細配線パッケージを断面図で示す。図６に示す第２実施形態では、第１実施形態における導体層４４に代えて、封止樹脂２２の表面に金属補強板４６を形成する。これにより、封止樹脂２２の表面が安定し、各電子部品１２、１４、１６の端子１２ａ、１４ａ、１６ａの位置が安定し且つ平坦化される。   6 to 9 are modifications of the fine wiring package of the present invention, and show the fine wiring package according to the second to fourth embodiments in cross-sectional views. In the second embodiment shown in FIG. 6, a metal reinforcing plate 46 is formed on the surface of the sealing resin 22 instead of the conductor layer 44 in the first embodiment. Thereby, the surface of the sealing resin 22 is stabilized, and the positions of the terminals 12a, 14a, and 16a of the electronic components 12, 14, and 16 are stabilized and flattened.

なお、この金属補強板４６は、第１実施形態における導体層４４と同様、配線層２８の一部がビア２６を介してこの金属補強板４６にも接続される。この第２実施形態に係る微細配線パッケージの他の製造工程は、第１実施形態の場合と同様である。また、この第２実施形態では、第２の支持体４０を剥離する際に接着剤層４２も共に剥離し、電子部品１２、１４、１６の背面が封止樹脂２２から露出するように形成しているが、第１実施形態の場合と同様に、第２の支持体４０を接着剤層４２から剥離し、電子部品１２、１４、１６の背面を接着剤層４２で覆うように構成しても良い。   The metal reinforcing plate 46 is also connected to the metal reinforcing plate 46 through the vias 26 in the same manner as the conductor layer 44 in the first embodiment. Other manufacturing processes of the fine wiring package according to the second embodiment are the same as those in the first embodiment. In the second embodiment, the adhesive layer 42 is also peeled off when the second support 40 is peeled, and the back surfaces of the electronic components 12, 14, 16 are exposed from the sealing resin 22. However, as in the case of the first embodiment, the second support 40 is peeled off from the adhesive layer 42, and the back surfaces of the electronic components 12, 14, 16 are covered with the adhesive layer 42. Also good.

図７に示す第３実施形態では、第１実施形態における導体層４４に代えて、キャビティ構造をもった金属補強板４８を使用する。この金属補強板８は、パッケージに組み込まれる受動素子１２や能動素子１４、１６等の電子部品を収容することのできるキャビティ１２ｂ、１４ｂ、１６ｂを有する。そして、第１実施形態における図３（ｂ）に対応する工程で、第２の支持体４０及び接着剤層４２を適用するのに代えて、キャビティ１２ｂ、１４ｂ、１６ｂを持った金属補強板４８を第１の支持体１０に接着剤２０を介して仮固定する。この場合において、金属補強板４８のキャビティ１２ｂ、１４ｂ、１６ｂはそれぞれの電子部品１２、１４、１６の背面側を覆うように配置すると共に、接着剤にて、各電子部品１２、１４、１６を金属補強板４８に固定する。   In the third embodiment shown in FIG. 7, a metal reinforcing plate 48 having a cavity structure is used in place of the conductor layer 44 in the first embodiment. The metal reinforcing plate 8 has cavities 12b, 14b, and 16b that can accommodate electronic components such as the passive element 12 and the active elements 14 and 16 incorporated in the package. Then, in the step corresponding to FIG. 3B in the first embodiment, instead of applying the second support 40 and the adhesive layer 42, a metal reinforcing plate 48 having cavities 12b, 14b, 16b. Is temporarily fixed to the first support 10 via an adhesive 20. In this case, the cavities 12b, 14b, 16b of the metal reinforcing plate 48 are arranged so as to cover the back sides of the respective electronic components 12, 14, 16, and each electronic component 12, 14, 16 is bonded with an adhesive. Fix to the metal reinforcement plate 48.

その後、図３（ｃ）に対応する工程で、第１の支持体１０を剥離し、各電子部品１２、１４、１６が金属補強板４８に保持された状態で、絶縁層２４、ビア２６、配線層２８等を多層に形成し、最上層にはソルダレジスト層３０、外部接続端子３２等を形成してパッケージを完成させる。この第３実施形態においても、配線層２８の一部がビア２６を介してキャビティを持った金属補強板４８にも接続される。   Thereafter, in a step corresponding to FIG. 3C, the first support 10 is peeled off, and the electronic component 12, 14, 16 is held by the metal reinforcing plate 48, and the insulating layer 24, the via 26, The wiring layer 28 and the like are formed in multiple layers, and the solder resist layer 30 and the external connection terminals 32 are formed on the top layer to complete the package. Also in the third embodiment, a part of the wiring layer 28 is also connected to the metal reinforcing plate 48 having a cavity through the via 26.

図８に示す第４実施形態では、第１実施形態における導体層４４に代えて、補強のために導電性の樹脂５０を形成する。この導電性樹脂５０により、封止樹脂２２の表面が安定し、各電子部品１２、１４、１６の端子１２ａ、１４ａ、１６ａの位置が安定し且つ平坦化される。なお、この導電性樹脂５０は、第１実施形態における導体層４４と同様、配線層２８の一部がビア２６を介して接続される。また、この第４実施形態では、第２の支持体４０を剥離する際に接着剤層４２も共に剥離し、電子部品１２、１４、１６の背面が封止樹脂２２から露出するように形成しているが、第１実施形態の場合と同様に、第２の支持体４０を接着剤層４２から剥離し、電子部品１２、１４、１６の背面を接着剤層４２で覆うように構成しても良い。 In 4th Embodiment shown in FIG. 8, it replaces with the conductor layer 44 in 1st Embodiment, and the conductive resin 50 is formed for reinforcement. The surface of the sealing resin 22 is stabilized by the conductive resin 50, and the positions of the terminals 12a, 14a, and 16a of the electronic components 12, 14, and 16 are stabilized and flattened. Note that the conductive resin 50 is connected to a part of the wiring layer 28 via the via 26, similarly to the conductor layer 44 in the first embodiment. In the fourth embodiment, the adhesive layer 42 is also peeled off when the second support 40 is peeled, and the back surfaces of the electronic components 12, 14, 16 are exposed from the sealing resin 22. However, as in the case of the first embodiment, the second support 40 is peeled off from the adhesive layer 42, and the back surfaces of the electronic components 12, 14, 16 are covered with the adhesive layer 42. Also good.

図９に示す第５実施形態では、第１実施形態における図５（ａ）に対応する工程において、第２の支持体４０をパッケージから剥離する際に、接着剤層４２も共に剥離する。これにより、電子部品１２、１４、１６の背面が封止樹脂２２から露出するように形成される。そして、一部の発熱性のある電子部品、例えば能動素子１４、１６の背面にヒートシング等の周知の放熱部品５２を設置する。   In the fifth embodiment shown in FIG. 9, when the second support 40 is peeled from the package in the step corresponding to FIG. 5A in the first embodiment, the adhesive layer 42 is also peeled off. Thus, the back surfaces of the electronic components 12, 14, 16 are formed so as to be exposed from the sealing resin 22. Then, a well-known heat dissipating component 52 such as heat sink is installed on the back surface of some heat-generating electronic components, for example, the active elements 14 and 16.

なお、図９に示すように、２つの能動素子１４、１６について共通の放熱部品５２を用いる場合は、放熱部品５２から能動素子１４、１６の背面までの異なるため、この段差を収拾するために比較的厚みのあり且つ熱伝導性の良好な接着剤５４を用いる。   As shown in FIG. 9, when using a common heat dissipation component 52 for the two active elements 14, 16, it is different from the heat dissipation component 52 to the back of the active elements 14, 16. A relatively thick adhesive 54 having good thermal conductivity is used.
