Abstract
【解決手段】半導体チップが積層され、隣接する半導体チップが複数の貫通ビアにより電気的に接続される半導体装置において、半導体チップは、コア回路とその周囲に配置された複数のIO回路とを有し、貫通ビア805はコア回路内に配置され、貫通ビア805の配置ピッチは、コア回路を構成するライブラリのセルピッチの整数倍である。
【選択図】図8
Description
前記チップは、IO回路とコア回路とを有し、
前記貫通ビアは前記コア回路に配置され、前記貫通ビアの配置ピッチは、前記コア回路を構成するライブラリのセルピッチの整数倍であることを特徴とする半導体装置とする。
前記半導体チップは、コア回路と前記コア回路の周囲に配置された複数のIO回路とを有し、
前記貫通ビアは、前記コア回路に配置されると共に前記IO回路のパッド電極に接続され、前記貫通ビアの配置ピッチは、前記コア回路を構成するライブラリのセルピッチの整数倍であることを特徴とする半導体装置とする。
(N−1)×h < a <N×h (1)
ここで、貫通ビアの配置間隔(配置ピッチ)をbとすると、適切な整数Mに対して以下の関係を満たすようにする。
b = 2Mh (2M > N) (2)
図9Aは、貫通ビア905の配置ピッチbを変えたときのデッドスペースの変化を説明するための図で、左側は配置ピッチbがセルピッチhの非整数倍の場合、右側は配置ピッチbがセルピッチhの整数倍の場合を示す。まず、1つの貫通ビア905において、KOZによるデッドスペースが最小になるように貫通ビア905を配置する。この上で、複数の貫通ビアを(2)式のように配置することで貫通ビアの位置にかかわらず、図9A右側で示したデッドゾーンは変化しない(セルピッチhの整数倍。ここではb=5h)。
以上、本実施例によれば、貫通ビアの配置効率が高い半導体装置を提供することができる。
以上、本実施例によれば、貫通ビアの配置効率が高い半導体装置を提供することができる。
以上、本実施例によれば、貫通ビアの配置効率が高い半導体装置を提供することができる。また、貫通ビアをコア回路に配置することで、その配置間隔をセルピッチの偶数倍という規則を守りつつ、実装可能なピッチまで拡大することができる(ピッチ設定の自由度が向上)。
以上、本実施例によれば、貫通ビアの配置効率が高い半導体装置を提供することができる。また、ウェル給電構造と標準セルの電源ラインとを兼用する構造により、チップ内のスペースをより有効に使用することができる。
