Abstract
【解決手段】外部と授受する電流容量が小さい電極パッドを基準とし、金属細線の細線化を実現している。そして、ICチップ2の電極パッド1に対し、同一径の金属細線5で接続をしている。一方、外部と大きい電流容量を授受する電極パッド1では、バンプ電極13を形成し、複数本の金属細線5を接続している。そのことで、大きい電流容量を授受でき、製造コスト低減、チップ面積の低減も実現することができる。

Description
第2に、前記第2の電極パッドは、Vcc用またはGND用のパッドであることで解決するものである。
第3に、第1のアイランド上に固着された第1の半導体チップと、前記第1のアイランドと離間して配置された第2のアイランド上に固着された第2の半導体チップと、前記第1のアイランドと前記第2のアイランドを囲むように設けられた複数のリードとを有する半導体装置に於いて、前記第1の半導体チップと前記第2の半導体チップとの対向する側辺に位置し、前記第1の半導体チップ側に設けられた複数の第1の電極パッドと、前記第1の半導体チップと前記第2の半導体チップとの対向する側辺に位置し、前記第2の半導体チップ側に設けられた第2の電極パッドと、前記第2の電極パッドに設けられたバンプ電極と、前記複数の第1の電極パッドの一つ目と前記バンプ電極とを接続する第1のボンディングワイヤと、前記複数の第1の電極パッドの二つ目と前記バンプ電極とを接続する第2のボンディングワイヤとを有し、前記バンプ電極側の前記第1のボンディングワイヤおよび前記第2のボンディングワイヤの付け根は、前記バンプ電極を形成する際に設けられる凸部の上を避けて設けられる事で解決するもので有る。
第4に、前記ボンディングワイヤの前記バンプ電極側は、スティッチボンドで形成されることで解決するものである。
1つの電極パッドで複数本の金属細線を接続することができるので、電極パッドの形成面積を統一して形成することができる。つまり、外部と授受する電流容量の大小によらず、電極パッドの形成面積を統一することができる。また、外部と授受する電流容量の大きい場合にも、形成する電極パッドの数を必要最低限の数とすることができる。そのことで、ICチップサイズの低減も実現することができる。
キャピラリ22の水平方向の位置はそのままで、その先端と金ボール27の上端(平坦部)との距離28が10〜30μm程度となるような位置でキャピラリ22を停止する。金ワイヤ24の付け根付近はキャピラリ22内部に収納されず、露出した状態となる。
