Abstract

화학적 기상성장법에 의한 박막형성에 있어서 생산선을 높혀 양호하며 또한 안정된 성막분포 및 막저항의 재현성을 얻는다.
1 또는 2이상의 기판을 반응실에 도입하여, 이 기판에반응가스를 도입하여 기판의 위에 화학적 기상성장법에 의해 박막을 퇴적시켜서 기판처리를 행하고, 도입된 기판마다에 기판처리를 반복 박막형성방법이며, 반복되는 기판처리의 사이의 비기판 처리시에 예컨대 기판 고정구에 퇴적한 박막의 표면을 부동태로하는 부동태화 가스를 반응실에 도입한다. 부동태화 가스는 예컨대 흡착가스로 구체적으로, 불활성가스와 0.1~10%의 NH3로 된 혼합가스, 또는 불활성가스와 0.1~10%의 SiH2Cl2로부터 이루어진 혼합가스이다. 부동태화 가스로서 산화가스를 사용할 수 있다.
