Description
本開示は、半導体表面から酸化物を不動態化、洗浄又は還元する方法に関する。
湿式洗浄は、例えば、ゲート誘電体の堆積又は接点形成に関連する操作を処理する前に、半導体表面を洗浄又は機能的にするための半導体プロセスである。湿式洗浄では、洗浄されるウェハは、例えば、洗浄剤(例えば、HFの水溶液)の浴槽内に浸漬される。半導体構造が、ますます増加しているアスペクト比を有する3次元(3D)形状(例えば、finFETデバイス)を含むように変化していくにつれて、湿式洗浄はより多くの問題を引き起こすであろう。用語finFETは、半導体材料の薄壁(又はフィン)のような形状の半導体構造体上に形成された電界効果トランジスタ(FET)を指す。フィンは3次元構造として機能し、3次元構造の中にはソース・ドレイン領域と、それらの間にチャネルが形成され、全てはフィンの3次元セクションに隣接するように形成される。ゲートは、壁の三辺に面したチャネルの上にある。完全な構造は、電界効果トランジスタ(FET)であり、finFETと呼ばれている。
