Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 良好な膜厚再現性を有し、且つHやOHの取 り込みが抑制された酸化膜形成方法を提供する。 【解決手段】 処理チャンバ1内の半導体ウェハを酸化 雰囲気中で加熱して酸化膜を形成する酸化膜形成方法で あり、触媒作用で水素を化学的に活性化し得る反応器2 6内に導入するとともにこの反応器26を水素の発火点 以下の温度に加熱して水素ラジカルを生成し、この水素 ラジカルを処理チャンバ1内に導入される酸素と反応さ せて水を生成しつつ半導体ウェハ上に酸化膜を形成して 行く酸化膜形成方法である。 (57) An object of the present invention is to provide a method for forming an oxide film, which has good film thickness reproducibility and in which H and OH uptake is suppressed. Kind Code: A1 A method for forming an oxide film by heating a semiconductor wafer in a processing chamber in an oxidizing atmosphere to form an oxide film, which is capable of chemically activating hydrogen by a catalytic action. 6 while heating the reactor 26 to a temperature below the ignition point of hydrogen to generate hydrogen radicals, and reacting the hydrogen radicals with oxygen introduced into the processing chamber 1 to generate water. This is a method for forming an oxide film in which an oxide film is formed on a semiconductor wafer.
