Abstract
Description
이때, 상기 플라즈마 건식 식각 공정은 60토르(Torr)의 압력 및 900∼1100와트(Watt)의 소오스 파워(source power)를 유지한 상태에서, CF4가스를 35∼45sccm 유량으로, Ar가스를 450∼550sccm 유량으로, O2가스를 20∼30sccm 유량으로, N2가스를 25∼35sccm 유량으로 각각 공급하여 진행한다.
또한, 본 발명은 비아 홀의 밀도를 높여줌으로써, 로딩 효과를 방지할 수 있으며, 패턴 밀도 차이에서 오는 비아 홀 오픈 페일(fail)을 막을 수 있다.
