Abstract:
1. A process for vapor depositing a low dielectric insulating film for a semiconductor device comprising the step of vapor depositing an a-SiCOH thin film by a CVD or PECVD method by supplying a reactant gas mixture comprising a gas phase main source, silane (SiH 4 ), and an oxidant to a vapor deposition chamber comprising a substrate, wherein the main source gas is selected as one or more in the group consisting of organosilicon compounds represented by the following Chemical Formulae 1, 2 and 3, wherein the ratio of silane (SiH 4 ) gas to main source gas is 1:0.5 to 1, and wherein the vapor deposition rate of a low dielectric insulating film is 1.006 to 1.266 microns/min: wherein, x is an integer, that is, 0, 1, 2 or 3, wherein, R wherein, R
