Title: 바이폴라 및 바이씨모스 디바이스의 제조방법
IPC: H01L21/331
Filed: 1999-03-11
Abstract: 비정질 실리콘이 좁은 갭에 증착된 디바이스 제조방법이 개시되었다.  갭은 2개의 물질층 사이에 있는 개구이다.  갭은 윈도우가 2개의 층중 하나에 형성되고 윈도우의 베이스에 제3 층의 일부가 제거될 때 발생한다.  바이폴라 디바이스의 형성에서, 산화물층은 실리콘 기판위에 형성되고 실리콘층은 디바이스에 대해 외부 베이스로서 작용하는 산화물층에 형성된다.  바이폴라 디바이스에서, 윈도우는 폴리실리콘내에 형성되고, 그리고나서 윈도우의 베이스에 산화물층이 제거된다.  바이폴라 디바이스에서, 실리콘 기판은 갭의 아래에 놓이고 외부 베이스 실리콘은 갭의 위에 놓인다.  산화물이 윈도우의 베이스로 부터 제거될 때, 외부 베이스 실리콘 아래에 있는 산화물층의 일부는 마찬가지로 제거되고, 그리하여 외부 베이스 실리콘과 아래 놓이는 실리콘 기판 사이에 갭을 형성하게 된다. 
     본 발명의 방법에서, 발생된 갭은 윈도우에 갭의 개구가 있는 근접 단부와 갭과 잔류 산화물 사이에 계면이 있는 말단부를 갖는다.  갭의 폭은 약 20nm 미만이다.  그리고 나서, 갭은 근접 단부에 높이가 말단부에 높이보다 더 큰 제1 높이를 갖는 조건으로 된다.  그 후 테이퍼진 갭은 폴리실리콘으로 충전된다.  그 테이퍼진 구조 때문에, 폴리실리콘은 뚜렷한 보이드없이 갭을 균일하게 충전한다.
