Abstract
【解決手段】セルウェル35と、セルウェル35上に形成され、メモリセルエリア11、及びセルウェルコンタクトエリア13を有するメモリセルアレイ3と、メモリセルエリア11に配置された第1配線体(BL、WL、SGD、SGS)と、セルウェルコンタクトエリア13に配置された第2配線体(CPWELL、WL、SGD、SGS)と、を備える。そして、第1配線体のレイアウトパターンと、第2配線体のレイアウトパターンとを同じとする。
【選択図】 図3
Description
図2は、図1に示すメモリセルアレイ3の回路例を示す回路図である。
図3〜図5は、図1に示すメモリセルアレイ3の構造例を示す平面図である。図3はゲートレイアウトパターン例を示し、以下同様に、図4は第1層メタル(M0)レイアウトパターン例を、図5は第2層メタル(M1)レイアウトパターン例を示す。また、図6は図3〜図5中の6−6線に沿う断面図、図7は図3〜図5中の7−7線に沿う断面図、図8は図3〜図5中の8−8線に沿う断面図である。
一実施形態では、セルウェルバイアス線CPWELLの下に、セルウェルコンタクト用ダミートランジスタを持つ。コンタクト用ダミートランジスタは、P型のセルウェル35と同じ導電型のP型ソース/ドレイン部分50を有する。コンタクト用ダミートランジスタは、一実施形態においては、図7に示したようにダミーブロック選択トランジスタDSTDである。セルウェルバイアス線CPWELLと、セルウェル35との接続(セルウェルコンタクト)は、P型ソース/ドレイン部分50を介して為される。
一般的に、ブロック選択線は、その抵抗値を下げるために、他の導電体層を用いてシャントする。このため、他の導電体層を、ブロック選択線に接続するブロック選択線コンタクトエリアが必要となる。このコンタクトエリアも、メモリセルアレイ3中のレイアウトパターンの周期性を崩す。
