Abstract
Description
이어서, 도 1e에 도시된 바와 같이 반도체 기판(101) 상에 형성된 유기 ARC 막(103)은 식각 공정에 의하여 반도체 기판(101)으로부터 제거된다.
블로킹 막(202)이 게이트 전극(203)의 상면 및 반도체 기판(201)의 상면에 형성된 후, 블로킹 막(202)이 덮이도록 유기 ARC 막(205)이 형성된다. 유기 ACR 막(205)은 게이트 전극(203)이 노출되지 않도록 후박하게 형성된다.
이어서, 유기 ARC 막(205)상 및 게이트 전극(203) 상에는 실리사이드 물질이 증착되고, 열처리 되어 게이트 전극(203) 상에는 실리사이드(204)가 형성되고, 게이트 전극(203) 이외의 부분은 모두 제거된다.
상기 실시예 또한 이온 주입 공정에 이용할 수 있으며, 이온 주입 공정 조건에 따라 블로킹 막의 두께를 조절할 수 있어, 첫번째 방법보다는 범용으로 사용 가능하다.
