Description
Claims (7)
- 반도체 제조 공정중 콘택 층의 디자인 룰을 공정상의 변경없이 멀티콘택 어레이 구조와 싱글 콘택 구조의 디자인 룰을 차별적으로 적용하는 것을 특징으로 하는 방법.
- 제1항에 있어서, 상기 콘택 구조는 메탈 콘택, 비아 콘택 등 배선을 위한 콘택을 포함하는 것을 특징으로 하는 방법.
- 제1항에 있어서, 상기 콘택 구조는 습식 식각시 BOE 용액 또는 HF 용액 등으로 공정을 진행하는 것을 특징으로 하는 방법.
- 제3항에 있어서, 상기 멀티콘택 어레이 구조에 습식식각을 진행시 콘택 스페이스 디자인 룰은 습식 식각양의 약 5배 정도를 적용하는 것을 특징으로 하는 방법.
- 제1항에 있어서, 상기 멀티용액 어레이 구조는 33 이상의 매트릭스 구조로 형성되어 있는 것을 특징으로 하는 방법.
- 반도체 장치의 콘택 식각 방법에 있어서, 상기 반도체 장치의 제조공정시 멀티 콘택 어레이 구조와 싱글콘택 구조에 대한 콘택 식각의 적용 디자인 룰을 구별하여 상기 멀티콘택 어레이 구조의 경우를 상기 싱글콘택 구조보다 큰 스페이스로 하는 것을 특징으로 하는 콘택식각 방법.
- 반도체 장치의 멀티콘택 식각 방법에 있어서, 상기 멀티콘택이 적어도 3개 이상의 행과 열의 매트릭스 구조로 이루어진 경우에 싱글콘택 구조에 대한 콘택 식각의 적용 디자인 룰보다 큰 디자인 룰로서 이루어진 상기 멀티콘택을 습식 식각함을 특징으로 하는 콘택식각 방법.
