Description

【発明の詳細な説明】
【0001】
【産業上の利用分野】この発明は、半導体装置用パッケ
ージに関する。
【0002】
【従来の技術】従来のガラス封止型半導体装置は、図3
に示すように、セラミック基板7上に低融点ガラス2を
介し、内部リード1bが固着され、セラミック基板7上
にICチップ5が固定さてた後に図4に示すようにIC
チップ上の電極8と内部リード1b先端部とを金属細線
6により電気的に接続し、低融点ガラス2もしくは熱硬
化型樹脂を介してキャップが固定され、半導体装置が形
成されていた。
【0003】
【発明が解決しようとする課題】この従来の半導体装置
用パッケージでは、ICチップ上の電極と、内部リード
を金属細線により導通させる場合、全ての内部リードに
おいて、先端の形状が単純であること、またリードフレ
ームを固定している低融点ガラスが光を反射することに
より、内部リードの位置を誤認識してしまいボンディン
グ不良となる場合が少なくなかった。
【0004】特に、一次元固体撮像素子(CCD)のよ
うなロングチップ用パッケージは、内部リード間隔が大
きいため誤認識となる場合が多く、ボンディング不良が
多発するといった問題点があった。
【0005】
【課題を解決するための手段】本発明の半導体装置用パ
ッケージは、リードフレームがセラミック基板にガラス
を介して固着されてなるガラス封止型の半導体装置用パ
ッケージにおいて、内部リードの少なくとも1本の先端
に凹部を有して構成されている。
【0006】
【実施例】次に本発明について図面を参照して説明する
。図1(a),(b)はそれぞれ本発明の第1の実施例
の上面図およびA部拡大図である。セラミック基板7上
に低融点ガラス2を介し、リードフレーム1及びウイン
ドフレーム3が固着され、セラミック基板上にCCDロ
ングチップ4が固定された後にCCDロングチップ上の
電極8と内部リード1b,凹部P付の内部リード1c先
端部とを金属細線6による電気的に接続し、熱硬化型樹
脂を介してキャップが固定される半導体装置用パッケー
ジである。
【0007】本実施例の半導体装置用のパッケージでは
、ボンディングパターン認識用の凹部P付き内部リード
1cを設け、他の内部リード1bと区別することにより
リード誤認識を防止してボンディング不良を低減する。 特に、一次元CCDのようなロングチップ用パッケージ
は、内部リード認識範囲が縦長である為、寸法誤差が大
きく、凹部付き内部リード1cのパターン認識により誤
認識を防止することが出来る。
【0008】図2は本発明の第2の実施例の一部拡大斜
視図で、V字型の凹部Qを内部リードに有している。
【0009】これらの形状のリードフレームは、従来の
エッチングプレス技術を用いて容易に形成が可能である
。本発明型の内部リード形状によるボンディング不良率
は0.04%であり、従来型の内部リードの場合の不良
率3.98%の100分の1に改善された。
【0010】
【発明の効果】以上説明したように本発明は、パターン
認識用の凹部付き内部リードを少なくとも1本設けるこ
とにより、ボンディング内部リード誤認識を防止し、ボ
ンディングずれなどの不良を100分の1に低減するこ
とが出来るという効果を有する。
【図面の簡単な説明】
【図1】(a),(b)はそれぞれ本発明の第1の実施
例の平面図およびA部拡大図である。
【図2】本発明の第2の実施例の一部拡大斜視図である
【図3】従来の半導体装置の一例の斜視図である。
