Description

本発明は、内部に半導体ＩＣを収容し、底面に他の装置との接続のための複数のパッドが設けられたＢＧＡパッケージに関する。   The present invention relates to a BGA package in which a semiconductor IC is accommodated and a plurality of pads are provided on the bottom surface for connection to other devices.

プリント配線基板にデバイスを実装するために、表面実装デバイスが用いられる。表面実装デバイスとして、図６に示すようなＢＧＡ（Ｂａｌｌ Ｇｒｉｄ Ａｒｒａｙ）パッケージの半導体デバイスがある。図において、ＢＧＡパッケージ１の下面には、パッド３が格子状に設けられ、更に、端子３には、はんだボール５が付着されている。   A surface mount device is used to mount the device on a printed wiring board. As a surface mount device, there is a BGA (Ball Grid Array) package semiconductor device as shown in FIG. In the figure, pads 3 are provided in a lattice pattern on the lower surface of the BGA package 1, and solder balls 5 are attached to the terminals 3.

一方、プリント配線基板（ＰＣＢ）７には、ＢＧＡパッケージ１のパッド３と対応するパッド９が設けられている。そして、はんだボール５がプリント配線基板７のパッド９に接するようにＢＧＡパッケージ１を配置し、外部から熱を加えてはんだボール５を融解し、ＢＧＡパッケージ１をプリント配線基板７に実装する。装置全体が小型化しつつある現状においては、ＢＧＡパッケージが広く使用されつつある。   On the other hand, the printed wiring board (PCB) 7 is provided with pads 9 corresponding to the pads 3 of the BGA package 1. Then, the BGA package 1 is arranged so that the solder balls 5 are in contact with the pads 9 of the printed wiring board 7, heat is applied from the outside to melt the solder balls 5, and the BGA package 1 is mounted on the printed wiring board 7. In the present situation where the entire apparatus is becoming smaller, BGA packages are being widely used.

一方、デジタル回路や高周波回路等のような高速な動作クロックを用いて作動する半導体デバイスがプリント配線基板に実装された場合には、電源ラインに電流変動ノイズが発生し、半導体デバイスに悪影響が及ぶことがある。そのため、ノイズ除去のために、半導体デバイスの電力供給端子の近傍にバイパスコンデンサ（パスコン）を設けることがある。   On the other hand, when a semiconductor device that operates using a high-speed operation clock such as a digital circuit or a high-frequency circuit is mounted on a printed wiring board, current fluctuation noise occurs in the power supply line, which adversely affects the semiconductor device. Sometimes. Therefore, a bypass capacitor (pass capacitor) may be provided in the vicinity of the power supply terminal of the semiconductor device in order to eliminate noise.

図７にその一例を示す。図はＢＧＡパッケージ１１が実装されたプリント配線基板１３の裏面を示している。破線で示す１５はＢＧＡパッケージ１１のパッドである。又、実線で示す１７は、プリント配線基板１３の表面と裏面とを配線するビアホール（Ｖｉａ Ｈｏｌｅ）である。このビアホール１７を用いてプリント配線基板１３の裏面に、バイパスコンデンサ１９が接続されている。   An example is shown in FIG. The figure shows the back surface of the printed wiring board 13 on which the BGA package 11 is mounted. Reference numeral 15 indicated by a broken line denotes a pad of the BGA package 11. Reference numeral 17 shown by a solid line is a via hole for wiring the front surface and the back surface of the printed wiring board 13. A bypass capacitor 19 is connected to the back surface of the printed wiring board 13 using the via hole 17.

しかし、信号ラインとの関係でビアホール１７によりプリント配線基板の裏面まで配線できる電源ラインには制限があり、ＢＧＡパッケージ１１の周縁にもバイパスコンデンサ１９′を設けている。   However, there is a limit to the power supply line that can be wired to the back surface of the printed wiring board through the via hole 17 in relation to the signal line, and a bypass capacitor 19 ′ is also provided at the periphery of the BGA package 11.

バイパスコンデンサは、電源ラインに可能な限り近く設けることが必要で、ＢＧＡパッケージ１１の周縁に設けたバイパスコンデンサ１９′は、ノイズ除去効果があまり期待できない。又、プリント配線基板１３も大きくなる。   The bypass capacitor must be provided as close as possible to the power supply line, and the bypass capacitor 19 ′ provided at the periphery of the BGA package 11 cannot be expected to have a noise removal effect. Moreover, the printed wiring board 13 is also enlarged.

そこで、ＢＧＡパッケージの場合、以下のような方法で、バイパスコンデンサを設けることが提案されている。
（１）ＢＧＡパッケージ内にバイパスコンデンサを設ける。 Therefore, in the case of the BGA package, it has been proposed to provide a bypass capacitor by the following method.
(1) A bypass capacitor is provided in the BGA package.

図８に示すように、半導体ＩＣ（チップ）２１はサブ基板２３上に設けられ、サブ基板２３には、半導体ＩＣ２１を覆い、半導体ＩＣ２１の上面に当接する蓋状の放熱板２５が設けられている。サブ基板２３の下面には、他の装置との接続のための複数のパッド２７が設けられ、更に、各パッド２７には、はんだボール２９が付着されている。そして、バイパスコンデンサ３１がサブ基板２３上に設けられている。
（２）ＢＧＡパッケージの上面にバイパスコンデンサを搭載する（例えば、特許文献１参照。）。
特開２００２−１８４８９４号公報（第４頁、図３参照） As shown in FIG. 8, the semiconductor IC (chip) 21 is provided on the sub-substrate 23, and the sub-substrate 23 is provided with a lid-like heat radiation plate 25 that covers the semiconductor IC 21 and contacts the upper surface of the semiconductor IC 21. Yes. A plurality of pads 27 for connection to other devices are provided on the lower surface of the sub-board 23, and solder balls 29 are attached to the pads 27. A bypass capacitor 31 is provided on the sub-board 23.
(2) A bypass capacitor is mounted on the top surface of the BGA package (see, for example, Patent Document 1).
JP 2002-184894 A (see page 4, FIG. 3)

しかし、上述した（１）（２）のような方法では、以下のような問題点がある。
（１）半導体ＩＣ１の面積が大きくなると、サブ基板２３にバイパスコンデンサ３１を設けるスペースがなくなる。バイパスコンデンサ３１をサブ基板２３にどうしても設けようとすると、ＢＧＡパッケージが大形化し、プリント配線基板も大形化する。
（２）ＢＧＡパッケージの上面に放熱フィンや放熱ファンを載せる場合は、バイパスコンデンサは搭載できない。 However, the methods (1) and (2) described above have the following problems.
(1) When the area of the semiconductor IC 1 is increased, there is no space for providing the bypass capacitor 31 on the sub-board 23. If the bypass capacitor 31 is inevitably provided on the sub-board 23, the BGA package is enlarged and the printed wiring board is also enlarged.
(2) When a heat radiating fin or a heat radiating fan is placed on the upper surface of the BGA package, a bypass capacitor cannot be mounted.

又、バイパスコンデンサの代わりに、電気的特性の向上のために抵抗やコイル等の回路部品を用いる場合であっても、上述の（１）、（２）に示す方法が可能であるが、同様な問題点が生じる。   Even when circuit components such as resistors and coils are used to improve electrical characteristics instead of bypass capacitors, the methods shown in the above (1) and (2) are possible. Problems arise.
