Description
下記式
そして、このデータより配線幅を2乗してボイドの成長速度に掛けて電流密度に対してプロットすると、図2(b)のように直線になることを見出した。このことより電流と配線幅の関係は次のように表すことができる。
この関係を各耐用年数に対して表すと図1のようになり、この図より配線幅W=0.1μmの配線に0.1mAの電流を流す耐用年数10年の配線の場合、0.2mAの電流を流すときは配線の幅WはW=0.126μmであればよいことがわかる。これより従来の0.2μmに比べ大幅に配線幅を減少できることができる。
この回路の場合、従来の設計では電流i1は電流i2の2倍なので、配線幅W1はW2の2倍の幅で設計されていたが、本願発明では、式(1)を用いてW1、W2、i1,i2の関係を求めると、
W1=W2×21/3となる。
ここで、W2を1とすると、W1=約1.26
となり、従来の設計値に比べ約37%配線幅を減少できる。
以上のように、式(1)または(2)の演算を行い配線の幅を決定すれば、配線幅の縮小が可能となる。
