Description
基板10上で、いくつかの実験が行われた。基板10は、物理的気相成長法(PVD)を用いて銅層20で金属化されたものである。また、基板10は、1nmから3nmの間の厚さの天然酸化銅による上面金属酸化物層22を有する。金属化基板10Mは、そのままの状態で、すなわち、前洗浄を行うことなく、ALD反応装置に設置される。使用された具体的なALD反応装置は、ウルトラテック ケンブリッジ ナノテック サバンナ(登録商標)反応装置である。金属化基板10Mは、直ちに真空下(0.1トール)に置かれ、150℃から170℃の間の温度に加熱された。
本開示の一局面は、半導体装置の製造において半導体構造を形成する処理の一部として、S−ALDを実行することを含む。
