Description
[0001]本発明の実施形態は、エレクトロニクス製造業、より具体的には、ハーフピッチ削減を可能にするパターニングプロセスに関する。
[0002]リソグラフィは集積回路(IC)の製造に使用される。図1A〜図1Cは、従来の半導体リソグラフィックプロセスの断面図を図示している。図1Aを参照すると、フォトレジスト層104が半導体スタック102上に与えられている。マスクつまりレチクル106がフォトレジスト層104上に位置決めされている。リソグラフィックプロセスは、図1Aに矢印で示されているように、具体的な波長(λ)を有する放射(hv)にフォトレジスト層104を露光することを含んでいる。図1Bを参照すると、フォトレジスト層104は引き続き現像されて、光に露光されたフォトレジスト層104の部分を除去することによって、半導体スタック102上にパターニング済みフォトレジスト層108を与える。パターニング済みフォトレジスト層108の各部材の幅は、部材の幅「x」と、各部材間の空間「y」とによって描かれている。空間「y」に付加された幅「x」はピッチpと称される。
