Abstract
Description
도 1은 여기서 개시된 청구 대상에 따른 예시적인 finFET, 또는 트라이-게이트 트랜지스터(100)를 도시한다.
도 2a 내지 도 2i는 여기서 개시된 청구 대상에 따른 콘택 구조를 형성하는 프로세스 단계들의 시퀀스를 도시한다.
도 3은 도 2a 내지 도 2i에 도시된 프로세스 단계들의 시퀀스에 대응하는 프로세스 플로우를 도시한다.
설명의 간소화 및 명료성을 위해, 도면에 도시된 구성요소들은 반드시 축적을 맞추어 도시될 필요는 없다는 것이 이해될 것이다. 예를 들면, 구성요소들 중 몇몇의 치수는 명료성을 위해 다른 구성요소에 비해 과장될 수 있다. 또한, 적절히 고려된다면, 참조 번호는 대응하는 및/또는 유사한 구성요소들을 가리키도록 도면들에서 반복되었다.
