Abstract
【解決手段】アルミ3と、アルミ3との間に層間絶縁膜を介して設けられたアルミ2と、アルミ2,3間を接続するコンタクトと、アルミ3に対応して設けられた保護膜の開口部1と、を備え、開口部1の内側領域が、外部電極用パッドであり、かつ、ボンディング領域とプローブテスト領域の二つに分けて使用される半導体装置である。前記ボンディング領域では、アルミ3が露出され、該アルミ3によりアルミ2が隠れている。前記プローブテスト領域では、アルミ2が露出されている。
【選択図】図1
Description
図1は本発明の第1実施形態による半導体装置のパッド部分のみを示した平面図である。具体例として、半導体チップ上に4つのパッドを一列に配置した場合が図示されている。この図において、長方形状の第3アルミ3が酸窒化シリコン膜(SiON)やポリイミド膜等の絶縁保護膜で覆われているが、その第3アルミ3の表面の上においては平面視T字形状の開口部1が設けられて、前記絶縁保護膜は存在しない。これにより、開口部1の内側領域における第3アルミ3の上面がパッドとして露出されている。
次に、図7(B)は、本発明に係るパッドを2個並べて配置した場合の平面図である。この図において、長方形状の第3アルミ3上に保護絶縁膜4の開口部1が設けられている。図7(B)中のa、b、cの寸法は、あらかじめ決まっている値であり、先の比較例の場合と同じ寸法となっている。ここで、本発明においては、第3アルミ3の下の層に第2アルミ2が設けられており、第2アルミ2が露出されている部分2aの外周部における保護絶縁膜4の覆い寸法についても、比較例と同様にdとなっている。
L1とL2を比較して明らかなように、本発明は比較例に対し、隣接するパッドの配置に必要な長さを、図7の左右方向において、寸法d+eだけ短縮することが可能である。3個以上のパッドを横1列に並べて配置する場合にも同様に、横方向に隣接する2つのパッドの配置に必要な長さを同寸法で短縮することが可能となる。
さらに、本発明に係るパッドの変形例(第2実施形態)について説明する。
さらに、本発明に係るパッドの別の変形例(第3実施形態)について説明する。
さらに、本発明に係るパッドの別の変形例(第4実施形態)について説明する。
以上、幾つかの実施形態を挙げて説明したように、本発明は、多層の金属配線層を有する半導体装置において、ボンディングおよびプローブテストを行うためのパッドを形成する場合に関するものである。
