Abstract
Description
기판상의 게이트 전극 예정영역에 감광막 패턴을 형성하는 단계;
상기 구조물 전면에 상기 감광막보다 식각률이 낮은 Low-k 물질 또는 탄소성 무기물로 유전막을 형성하는 단계;
상기 감광막과 유전막의 식각률 차이를 이용한 에치백으로 상기 감광막을 제거하여 상기 게이트 전극 예정영역을 노출시키는 유전막을 남기는 단계;
상기 구조물 표면에 게이트 절연막과 금속층을 형성하는 단계;
상기 유전막을 식각 종말점으로 상기 금속층과 게이트 절연막을 전면 식각하여 상기 유전막 사이의 게이트 전극 예정영역을 매립하는 게이트 전극을 형성하는 단계;
상기 유전막을 제거하는 단계를 포함하는 것을 특징으로 한다.
