Description

【発明の詳細な説明】 本発明は半導体集積回路の内部接続（以下ボン
デングという）方法に関するものである。
第１図イ，ロにおいて、従来より、半導体集積
回路のペレツト１と、リード２とを接続するには
接続導線として金ワイヤなどを使用し、いずれの
側に対しても熱圧着法によりボンデングを行なつ
ていた。しかしこの方法によるときにはリード２
側の接着性を向上するためにリード素材（コバ
ー、42合金等）の表面に予じめ金あるいは銀メツ
キなどを施こさなければならないという欠点があ
つた。さらにペレツト１とリード２とを金ワイヤ
３などで接続した後、これを合成樹脂などで保護
するのであるが、この操作中、合成樹脂材がリー
ド２の表面に付着すると、後にリード処理工程と
して必要なすずメツキ処理において、合成樹脂が
被着したその表面にすずメツキを施すことが困難
となるため、リード処理工程の以前にリード表面
に付着した合成樹脂を除去しなければならなかつ
た。
本発明は上記問題点を解消するもので、硬質絶
縁治具と、該硬質絶縁治具の外周に相対変位可能
と備えた輪状の導電治具とを交互に用いペレツト
側のボンデングは従来どおり熱圧着法によつて行
ない、リード側のボンデングを電気スポツト溶接
によつて行なうことにより、従来リード表面に前
処理として必要とされた金メツキの処理を不要な
らしめ、併せて予じめリード素材表面にすずメツ
キを施こすことにより、後の合成樹脂の除去工程
を不用ならしめてボンデング工程の簡略化を図る
ことを特徴とするものである。
以下本発明の実施例を第２図イ，ロ，ハによつ
て説明する。本発明はペレツト１側のボンデング
を熱圧着方法で行ない、リード２側のボンデング
を電気スポツト溶接法で行なうものであるが、こ
の操作を行なう器具として円形断面を有する筒状
の熱圧着用の硬質絶縁治具（キヤピラリ）４と、
その周囲に相対変位可能に配置した電気スポツト
接着用輪状の導電治具（電極）５との組み合わせ
器具７を用いる。
キヤピラリ４および電極５は同軸に取付けられ
ており、それぞれ交互に独立した上下動を行なう
ように組み合わされているものである。この器具
を用いて本発明のボンデングを行なう場合につい
て説明する。
実施例は、リードフレーム６に支えられたペレ
ツト１と、リード２とをそれぞれ熱圧着接合およ
び電気スポツト溶接により金ワイヤ３を接合する
場合の例を示す。ペレツト１は予じめ適宜の加熱
手段により加熱されており、このペレツト１に対
しては、第２図イに示すように従来と同様にキヤ
ピラリ４内を挿通してその下端より引き出した金
ワイヤ３先端をキヤピラリ４の端縁でペレツト１
に押しつけて熱圧着をする。
この燥作の際に、電極５は金ワイヤ３の圧着面
よりわずか上方に逃げた状態にある。ペレツト１
へのボンデングを完了した後、次に第２図ロに示
すように器具７をリード２側に移す。リード２へ
の金ワイヤ３のボンデングは電気スポツト溶接に
より行なうため、リード２の表面には予じめすず
メツキを施しておく。
リード２の上方に移した器具７におけるキヤピ
ラリ４は圧着面よりわずか上方に逃げ、同時に電
極５はリード２の圧着面に金ワイヤ３を介して電
気的に接続させる。リード２の下方にはグランド
電極８が設けられ、電源回路のスイツチ９を閉
じ、両電極５，８間に電源１０を投入する。電極
５，８に金ワイヤおよびリード２を介して通電さ
れ、この間の抵抗熱により電極５の端縁にて圧着
された金ワイヤ３とリード２とがスポツト溶接さ
れて金ワイヤ３がリード２に接合される。次に第
２図ハに示すようにリード２に接合された金ワイ
ヤ３をその接合部で切断し、リード２側のボンデ
ングを完了する。
本発明は以上のようにペレツト側ボンデングを
通常の如く熱圧着方式で行ない、リード側ボンデ
ングを電気スポツト溶接で行なうためにリード表
面には金メツキ処理を施こしておく必要がないば
かりか、予じめリード２の表面にすずメツキ処理
を施こしたうえで電気スポツト溶接を行なうこと
が可能となるためにボンデング後、合成樹脂被着
を行なつた場合にリード面上に付着した合成樹脂
材をその後の工程で除去する必要がなくなり、し
たがつてボンデング工程を簡略化できる。また、
本発明方法によれば、熱圧着用のキヤピラリ４
と、電気スポツト溶接用の電極５とを組み合わせ
た器具７と用い、キヤピラリ４と電極５とを交互
に上下動させることによつて簡単な操作によりキ
ヤピラリ又は電極の端縁で金ワイヤを抑えてそれ
ぞれリードおよびペレツトのボンデングを行なう
効果を有するものである。
