Description
以下、図面を参照しながら、実施形態に係る半導体装置について説明する。以下の説明において、同一の機能及び構成を有する要素については、同一符号を付し、重複する説明は必要に応じて行う。
図1乃至図7を参照して、第1の実施形態の半導体装置について、説明する。
図1に示される本実施形態の半導体装置9において、半導体集積回路が形成された半導体チップ(半導体基板)が、絶縁体99に覆われている。
半導体装置9は、例えば、半導体メモリである。
半導体領域10は、ドナー又はアクセプタを含むウェル領域であり、n型ウェル領域でもよいし、p型ウェル領域でもよい。
尚、ここで示される半導体領域10/キャパシタ電極15の延在方向とパッド配列方向(絶縁体の辺)との関係は、一例であって、半導体領域10及びキャパシタ電極15は、パッド配列方向と交差する方向に延在していてもよい。
アノードとしてのp型ウェル領域30は、コンタクト38B、メタル層M0及びビアプラグV1を介して、メタル層M1に接続されている。p型ウェル領域30は、メタル層M1に接続されたビアプラグV2を介して、メタル層M2に接続されている。n型拡散層3のコンタクト形成領域内に、コンタクト38Aが接続されている。コンタクト38Aは、例えば、メタル層M0及びビアプラグV1を介して、メタル層M1に接続される。
図8及び図9を用いて、第2の実施形態の半導体装置について、説明する。
図10及び図11を用いて、第3の実施形態の半導体装置について、説明する。
図12及び図13を用いて、第4の実施形態の半導体装置について説明する。
それゆえ、図12及び図13に示されるように、キャパシタ領域91内に設けられたキャパシタ1Cが、メモリセルトランジスタMTの積層ゲート構造と実質的に同様の積層体を含み、絶縁膜14を挟んで積層された2つの導電体が、キャパシタ1Aの電極13,15として用いられてもよい。
図14を用いて、実施形態の半導体装置の適用例について、説明する。
上述の実施形態において、NAND型フラッシュメモリが、半導体チップに形成される半導体集積回路として例示されている。ただし、これに限定されず、半導体集積回路は、他の回路構成(例えば、NOR型)のフラッシュメモリ、DRAM、SRAM、MRAM、ReRAM、PCRAMなどの半導体メモリでもよいし、ロジック回路でもよいし、或いは、半導体メモリとロジック回路とが混載されたシステムLSIでもよい。
