WebJun 1, 1982 · Abstract. The dependence of the step coverage of chemically vapor deposited undoped SiO 2 glass films on the deposition pressure is reported. It has been found that the step coverage is significantly improved when the deposition pressure is increased by reducing the pumping speed. Increasing the pressure by the addition of … WebMar 25, 2024 · (a:Good Step Coverage b:Poor Step Coverage) 4.Filling:단차 사이 공간을 잘 채우는지 . 위의 그림에서. 사이 공간을 증착으로 채우다보면. 단차 사이 안쪽이 잘 안 채워지다보니 (c)처럼 채워지게 됩니다.
