Abstract
【解決手段】半導体基板にゲート電極を形成する段階と、ゲート電極に側壁スペーサを形成する段階と、側壁スペーサの両側の半導体基板を一部エッチングしてトレンチを形成する段階と、トレンチ内にSiGe混晶層を形成する段階と、SiGe混晶層上にシリコン層を形成する段階と、シリコン層の面の結晶方向に従って、エッチング率が異なるエッチング液を利用してシリコン層の一部をエッチチングすることによって111傾斜面を有するシリコンファセット(Si facet)を含むキャッピング層を形成する段階と、を有する。キャッピング層を含むことによって半導体素子でホールの移動度が高まる。キャッピング層内のピッティング不良が減少することによって半導体素子の特性が良好になる。
