Abstract

The SiOC films were deposited with the variation of flow rate ratios by chemical vapor deposition. It was researched the reason of decreasing the dielectric constant in SiOC film and the relationship between the dielectric constant and the thickness. The thickness of the deposited films tends to in proportion to the refractive index and the sample with the lowest dielectric constant decreased the thickness. The refractive index was decreased after annealing because of the decreasing of the film's thickness by annealing process.

SiOC 박막은 화학적 증착 방법에 의해 여러 가지 유량비를 다르게 하여 증착되었다. SiOC 박막에서 유전상수의 감소원인에 대하여 조사하고 샘플들은 박막의 두께와 유전상수사이의 상관성에 대하여 분석하였다. 증착한 샘플에서 박막의 두께는 굴절률에 비례하는 경향성이 있으며, 유전상수가 가장 낮은 샘플에서 두께는 감소되었다. 굴절률은 열처리 후 감소하였는데, 열처리 하면서 박막의 두께가 감소되었기 때문이다.
