Description

本発明は、回路基板に半導体パッケージを実装して構成されるプリント回路板に関する。また、本発明は、当該プリント回路板の一部である半導体パッケージ、および、当該プリント回路板を備える電子機器に関する。   The present invention relates to a printed circuit board configured by mounting a semiconductor package on a circuit board. The present invention also relates to a semiconductor package that is a part of the printed circuit board, and an electronic device including the printed circuit board.

従来文献(特許文献1)には、プリント回路板の一例が示されている。このプリント回路板では、半導体パッケージを回路基板に実装するために、金属細線およびシリコーンゴムからなる部材を、半導体パッケージと回路基板との間に配設している。ここで、金属細線およびシリコーンゴムからなる部材は変形するため、半導体パッケージと回路基板との熱膨張係数の相違に起因する接続不良が防止される。   An example of a printed circuit board is shown in a conventional document (Patent Document 1). In this printed circuit board, in order to mount the semiconductor package on the circuit board, a member made of a fine metal wire and silicone rubber is disposed between the semiconductor package and the circuit board. Here, since the member made of the fine metal wire and the silicone rubber is deformed, poor connection due to the difference in the thermal expansion coefficient between the semiconductor package and the circuit board is prevented.

他の従来文献(特許文献2)には、プリント回路板の別の一例が示されている。このプリント回路板では、半導体パッケージを回路基板に実装するために、半導体パッケージの裏面に配列された複数のバンプが、回路基板の表面に配列された複数の導電性パッドに接合される。ここで、半導体パッケージを回路基板に実装する際に、複数の導電性パッドの間にアンダーフィルを塗布することにより、はんだブリッジの形成を防止している。   Another conventional document (Patent Document 2) shows another example of a printed circuit board. In this printed circuit board, in order to mount the semiconductor package on the circuit board, a plurality of bumps arranged on the back surface of the semiconductor package are bonded to a plurality of conductive pads arranged on the surface of the circuit board. Here, when the semiconductor package is mounted on the circuit board, formation of a solder bridge is prevented by applying an underfill between the plurality of conductive pads.

BGA(Ball Grid Alley)やCSP(Chip Size Package)などのバンプを有する半導体パッケージにおいて、半導体パッケージおよび回路基板をアンダーフィル接着剤を用いて接着する場合には、半導体パッケージと回路基板との隙間にアンダーフィル接着剤を充填して硬化させる。ここで、アンダーフィル接着剤は半導体パッケージの外側から流し込んで供給するため、アンダーフィル接着剤は半導体パッケージと回路基板との間の領域からはみ出す。よって、回路基板上の電子部品を搭載するためのスペースは無駄に使われてしまう。   In a semiconductor package having bumps such as BGA (Ball Grid Alley) and CSP (Chip Size Package), when the semiconductor package and the circuit board are bonded using an underfill adhesive, the gap between the semiconductor package and the circuit board is used. Fill with underfill adhesive and cure. Here, since the underfill adhesive is supplied by being poured from the outside of the semiconductor package, the underfill adhesive protrudes from the region between the semiconductor package and the circuit board. Therefore, the space for mounting the electronic components on the circuit board is wasted.

It is sectional drawing which looked at the board 3 from the direction parallel to a board surface. 2A corresponds to the aa cross section of FIG. 2B, and FIG. 2B corresponds to the bb cross section of FIG. 2A.

プリント回路板3は、電子部品を搭載するための回路基板20と、内部に半導体ウェーハを有する半導体パッケージ10と、半導体パッケージ10を回路基板20に接続するバンプ12およびランド22と、半導体パッケージ10を回路基板20に接着する接着部材30と、を備えている。   The printed circuit board 3 includes a circuit board 20 for mounting electronic components, a semiconductor package 10 having a semiconductor wafer therein, bumps 12 and lands 22 for connecting the semiconductor package 10 to the circuit board 20, and the semiconductor package 10. And an adhesive member 30 that adheres to the circuit board 20.

回路基板20は、電子部品を搭載するために設けられた板状の部材であり、その表層および内層には銅箔により形成された多数の配線が形成されている。回路基板20は上面20aおよび下面20bを有しており、回路基板20の上面20aには、エリアアレイ型の構造をした多数のランド22が形成されている。また、回路基板20の上面20aには、接着部材30が接着されて配置されている。   The circuit board 20 is a plate-like member provided for mounting electronic components, and a large number of wirings formed of copper foil are formed on the surface layer and the inner layer. The circuit board 20 has an upper surface 20a and a lower surface 20b. On the upper surface 20a of the circuit board 20, a number of lands 22 having an area array structure are formed. In addition, an adhesive member 30 is bonded to the upper surface 20a of the circuit board 20.

半導体パッケージ10は、BGA(Ball Grid Alley)やCSP(ChipSize Package)などの半導体ウェーハを内部に有するパッケージである。半導体パッケージ10は、略矩形の板状の部材であり、回路基板20と対向して回路基板20に平行に設けられている。半導体パッケージ10は上面10aおよび下面10bを有しており、半導体パッケージ10の下面10bは回路基板20に対向する対向面である。半導体パッケージ10の下面10bには、エリアアレイ型の構造をした多数のバンプ12が形成されている。また、半導体パッケージ10の下面10bには、接着部材30が接着されて配置されている。   The semiconductor package 10 is a package having a semiconductor wafer such as BGA (Ball Grid Alley) or CSP (ChipSize Package) inside. The semiconductor package 10 is a substantially rectangular plate-like member, and is provided in parallel to the circuit board 20 so as to face the circuit board 20. The semiconductor package 10 has an upper surface 10 a and a lower surface 10 b, and the lower surface 10 b of the semiconductor package 10 is a facing surface that faces the circuit board 20. A large number of bumps 12 having an area array type structure are formed on the lower surface 10 b of the semiconductor package 10. Further, an adhesive member 30 is bonded and disposed on the lower surface 10 b of the semiconductor package 10.

バンプ12の各々は、はんだや金などを材質とする略球状の部材である。バンプ12の各々は、上面12aおよび下面12bを有している。各バンプ12の上面12aは半導体パッケージ10に接合されており、各バンプ12の下面12bはランド22に接合されている。ランド22の各々は、回路基板20の表層に形成された配線と同様に、銅箔により形成されている。ランド22の各々は、上面22aおよび下面22bを有している。各ランド22の上面22aはバンプ12に接合されており、各ランド22の下面22bは回路基板20に接合されている。   Each of the bumps 12 is a substantially spherical member made of solder or gold. Each of the bumps 12 has an upper surface 12a and a lower surface 12b. The upper surface 12 a of each bump 12 is bonded to the semiconductor package 10, and the lower surface 12 b of each bump 12 is bonded to the land 22. Each of the lands 22 is formed of a copper foil similarly to the wiring formed on the surface layer of the circuit board 20. Each land 22 has an upper surface 22a and a lower surface 22b. The upper surface 22 a of each land 22 is bonded to the bump 12, and the lower surface 22 b of each land 22 is bonded to the circuit board 20.

既述のとおり、バンプ12およびランド22は、エリアアレイ型の構造をしている。より詳しく説明すると、多数のバンプ12が、半導体パッケージ10の下面10bにおいて一定間隔をあけて2次元的に配列されている。また、バンプ12と同数のランド22が、回路基板20の上面20aにおいて一定間隔をあけて2次元的に配列されている。そして、各対となるバンプ12およびランド22が互いに接合されることにより、半導体パッケージ10と回路基板20とが機械的に接合される。この結果、半導体パッケージ10と回路基板20とが電気的に接続される。なお、本実施形態では、バンプ12およびランド22は8×8のエリアアレイ型構造であるが、バンプ12およびランド22の個数はそれよりも多くてもよいし、それよりも少なくてもよい。   As described above, the bump 12 and the land 22 have an area array type structure. More specifically, a large number of bumps 12 are two-dimensionally arranged at regular intervals on the lower surface 10b of the semiconductor package 10. Further, the same number of lands 22 as the bumps 12 are two-dimensionally arranged on the upper surface 20a of the circuit board 20 with a predetermined interval. The semiconductor package 10 and the circuit board 20 are mechanically bonded to each other by bonding the bumps 12 and the lands 22 that are paired with each other. As a result, the semiconductor package 10 and the circuit board 20 are electrically connected. In the present embodiment, the bumps 12 and the lands 22 have an 8 × 8 area array structure, but the number of the bumps 12 and the lands 22 may be larger or smaller.

接着部材30は、半導体パッケージ10および回路基板20に接着されて、半導体パッケージ10および回路基板20の接合を補強する。接着部材30はゴム素材で形成されているため、プリント回路板3に衝撃や振動が作用した際には、その衝撃や振動を吸収して緩和する。接着部材30は、半導体パッケージ10および回路基板20により挟まれた領域において、半導体パッケージ10の外縁10jに沿って配設されている。接着部材30の外周面30jは半導体パッケージ10の外縁10jよりも若干内側方向(半導体パッケージ10の中心方向)に退避しており、接着部材30は半導体パッケージ10からはみ出していない。なお、接着部材30の内周面30kは、バンプ12およびランド22に沿って配設されており、バンプ12およびランド22に対向している。   The bonding member 30 is bonded to the semiconductor package 10 and the circuit board 20 to reinforce the bonding between the semiconductor package 10 and the circuit board 20. Since the adhesive member 30 is formed of a rubber material, when an impact or vibration is applied to the printed circuit board 3, the adhesive member 30 absorbs and relaxes the impact or vibration. The adhesive member 30 is disposed along the outer edge 10 j of the semiconductor package 10 in a region sandwiched between the semiconductor package 10 and the circuit board 20. The outer peripheral surface 30j of the adhesive member 30 is retracted slightly inwardly of the outer edge 10j of the semiconductor package 10 (the central direction of the semiconductor package 10), and the adhesive member 30 does not protrude from the semiconductor package 10. The inner peripheral surface 30k of the adhesive member 30 is disposed along the bump 12 and the land 22 and faces the bump 12 and the land 22.

本実施形態のプリント回路板3では、半導体パッケージ10からはみ出さないように接着部材30が配設されているため、接着部材30を用いて半導体パッケージ10と回路基板20との接合を補強することができると共に、プリント回路板3上の電子部品を搭載するためのスペースを効率的に利用することができる。すなわち、接着部材30が半導体パッケージ10からはみ出さないため、半導体パッケージ10に近接した位置に他の電子部品や配線などを配設して、プリント回路板3における電子部品の実装密度を向上することができる。   In the printed circuit board 3 of the present embodiment, since the adhesive member 30 is disposed so as not to protrude from the semiconductor package 10, the bonding between the semiconductor package 10 and the circuit board 20 is reinforced using the adhesive member 30. In addition, the space for mounting the electronic components on the printed circuit board 3 can be used efficiently. That is, since the adhesive member 30 does not protrude from the semiconductor package 10, other electronic components, wirings, and the like are disposed in the vicinity of the semiconductor package 10 to improve the mounting density of the electronic components on the printed circuit board 3. Can do.

また、本実施形態のプリント回路板3では、接着部材30は矩形の枠状に形成されており、比較的に簡易な形状であるため製造に適している。但し、本実施形態では接着部材30は矩形の枠状であったが、他の実施形態では接着部材30は少なくとも4つの頂部(図1にて破線で囲われる範囲)30a,30b,30c,30dの位置に配置されればよい。接着部材30が少なくとも4つの頂部30a,30b,30c,30dの位置に配置されることにより、半導体パッケージ10と回路基板20との機械的な接合を十分に補強することができる。   Further, in the printed circuit board 3 of the present embodiment, the adhesive member 30 is formed in a rectangular frame shape and has a relatively simple shape, which is suitable for manufacturing. However, in the present embodiment, the adhesive member 30 has a rectangular frame shape, but in other embodiments, the adhesive member 30 has at least four apexes (a range surrounded by a broken line in FIG. 1) 30a, 30b, 30c, 30d. It suffices if it is arranged at the position. By disposing the adhesive member 30 at the position of at least four top portions 30a, 30b, 30c, and 30d, the mechanical bonding between the semiconductor package 10 and the circuit board 20 can be sufficiently reinforced.

また、本実施形態のプリント回路板3では、半導体パッケージ10と接着部材30との接着、回路基板20と接着部材30との接着は、各界面にて比較的に剥がしやすいため、半導体パッケージ10の交換が必要となった場合には、半導体パッケージ10の交換作業を容易に行うことができる。   In the printed circuit board 3 of the present embodiment, the adhesion between the semiconductor package 10 and the adhesive member 30 and the adhesion between the circuit board 20 and the adhesive member 30 are relatively easy to peel off at each interface. When replacement is required, the semiconductor package 10 can be easily replaced.

In the second embodiment, the adhesive member 40 includes four component pieces 40A, 40B, 40C, and 40D.

In FIG. 9, the manufacturing process of the printed circuit board 3 of the first embodiment is shown as a representative.

図9(a)に示されるように、第1工程において、バンプ12付きの半導体パッケージ10および接着部材30を用意する。ここで、接着部材30は、図1、図3、図5または図7の形状に予め成形されている。そして、バンプ12付きの半導体パッケージ10に接着部材30を接着する。ここで、半導体パッケージ10に接着部材30を接着するためには、半導体パッケージ10と接着部材30とを接触させてから接触部分を加熱すればよい。この結果、半導体パッケージ10と接着部材30とが互いに接着され、半導体パッケージ10および接着部材30からなるサブアッセンブリー8が形成される。   As shown in FIG. 9A, in the first step, the semiconductor package 10 with the bumps 12 and the adhesive member 30 are prepared. Here, the adhesive member 30 is pre-formed into the shape of FIG. 1, FIG. 3, FIG. 5 or FIG. Then, the adhesive member 30 is bonded to the semiconductor package 10 with the bumps 12. Here, in order to bond the adhesive member 30 to the semiconductor package 10, the contact portion may be heated after the semiconductor package 10 and the adhesive member 30 are brought into contact with each other. As a result, the semiconductor package 10 and the adhesive member 30 are bonded to each other, and the subassembly 8 including the semiconductor package 10 and the adhesive member 30 is formed.

図9(b)に示されるように、第2工程において、回路基板20にサブアッセンブリー8を接合する。ここで、回路基板20に接着部材30を接着するためには、回路基板20と接着部材30とを接触させてから接触部分を加熱すればよい。なお、バンプ12とランド22を接合するためのリフロー工程を経ることで、回路基板20と接着部材30との接触部分を加熱して、回路基板20に接着部材30を接着してもよい。この結果、図9(c)に示されるように、プリント回路板3が完成する。   As shown in FIG. 9B, the subassembly 8 is joined to the circuit board 20 in the second step. Here, in order to bond the adhesive member 30 to the circuit board 20, the contact portion may be heated after the circuit board 20 and the adhesive member 30 are brought into contact with each other. Note that the contact member between the circuit board 20 and the adhesive member 30 may be heated to bond the adhesive member 30 to the circuit board 20 through a reflow process for bonding the bumps 12 and the lands 22. As a result, as shown in FIG. 9C, the printed circuit board 3 is completed.

上述したプリント回路板3の製造方法によれば、プリント回路板3を図1、図3、図5または図7の形状に予め成形されているため、接着部材30を半導体パッケージ10と回路基板20との間に配置する際に、アンダーフィル接着剤の供給装置のような特殊な製造装置を必要とすることがない。よって、本実施形態の接着部材30を用いることにより、プリント回路板3の製造工程を簡略化し、製造コストを低減することができる。   According to the method of manufacturing the printed circuit board 3 described above, since the printed circuit board 3 is pre-shaped in the shape of FIG. 1, FIG. 3, FIG. 5, or FIG. Therefore, a special manufacturing device such as an underfill adhesive supply device is not required. Therefore, by using the adhesive member 30 of this embodiment, the manufacturing process of the printed circuit board 3 can be simplified and the manufacturing cost can be reduced.

また、上述したプリント回路板3の製造方法によれば、接着部材30がゴム系高分子材料で形成されているため、リフロー工程のみで接着部材30を回路基板20に確実に接着することができる。なお、接着部材30をエポキシ樹脂やアクリル樹脂などの樹脂素材で形成した場合には、これらの樹脂素材はリフロー工程のみでは十分に硬化しないため、アフターキュア工程が必要となってしまう。一方、本実施形態のようにゴム系高分子材料の接着部材30を用いた場合には、アフターキュア工程を必要とせず、製造工程を簡略化することができる。   Moreover, according to the manufacturing method of the printed circuit board 3 mentioned above, since the adhesive member 30 is formed with the rubber-type polymer material, the adhesive member 30 can be reliably adhere | attached on the circuit board 20 only by a reflow process. . In addition, when the adhesive member 30 is formed of a resin material such as an epoxy resin or an acrylic resin, these resin materials are not sufficiently cured only by the reflow process, and thus an after cure process is required. On the other hand, when the rubber-based polymer material adhesive member 30 is used as in the present embodiment, an after-curing process is not required, and the manufacturing process can be simplified.

また、本実施形態では、接着部材30は図1、図3、図5または図7の所定形状に予め成形されている。エポキシ樹脂やアクリル樹脂などのアンダーフィル接着剤を用いた場合には、液状のアンダーフィル接着剤を半導体パッケージ10と回路基板20との間に流し込むため、液状のアンダーフィル接着剤が回路基板20に形成されたスルーホールや部品穴に入ってしまうおそれがある。本実施形態では、接着部材30は所定の形状に予め成形されているため、回路基板20に形成されたスルーホールや部品穴に入ってしまうことを未然に防止することができる。   In the present embodiment, the adhesive member 30 is preliminarily molded into the predetermined shape shown in FIG. 1, FIG. 3, FIG. 5, or FIG. When an underfill adhesive such as an epoxy resin or an acrylic resin is used, the liquid underfill adhesive is poured between the semiconductor package 10 and the circuit board 20, so that the liquid underfill adhesive is applied to the circuit board 20. There is a risk of entering the formed through hole or component hole. In the present embodiment, since the adhesive member 30 is preliminarily formed into a predetermined shape, it can be prevented in advance that the adhesive member 30 enters a through hole or a component hole formed in the circuit board 20.
