Abstract
Description
US-B-6 316 302는 동일한 기판 상에 NMOS 및 PMOS 트랜지스터들을 형성하는 방법을 개시한다. 상기 방법은 NMOS 및 PMOS의 LDD 및 주요 소스/드레인 영역들의 형성을 위한 측벽 스페이서들의 이방성 식각을 포함한다.
반도체 디바이스 및 그의 집적 회로의 제조는 반도체 기판에서 시작하여, 반도체 기판 내에 또는 반도체 기판 상에 다양한 구조적 특성(feature)들을 형성하기 위하여 막 형성, 이온 주입, 포토리소그래피, 식각 및 증착 기술들을 이용하여 개별적인 회로 성분들이 얻어지고, 이후 개별적인 회로 성분들은 최종적으로 집적 반도체 디바이스를 형성하기 위해 상호 연결된다. 초대규모 집적(ULSI : ultra large scale integration) 반도체 디바이스에 관련된 고밀도 및 고성능 요구가 높아지고 있고, 구조적 요소의 축소, 트랜지스터 속도 및 회로 속도의 고속화, 고신뢰도 및 생산 처리량을 증가하여, 경쟁력을 높이는 것이 요구된다. 디바이스들 및 구조들이 작아짐에 따라, 그리고 고성능 디바이스의 요구가 증가함에 따라, 새로운 제조 방법들 및 새로운 배치를 필요로 하는 새로운 문제점들이 발견되었다.
