Abstract:
A method of fabricating a semiconductor device, comprising the steps in sequence of:(a) forming a lower electrode of a capacitor on a first insulating film; said first insulating film being formed on or over a semiconductor substrate; (b) forming a dielectric film of said capacitor on said lower electrode to be overlapped therewith; (c) forming an upper electrode of said capacitor on said dielectric film to be overlapped therewith; and (d) forming a second insulating film to cover said capacitor by a thermal CVD process in an atmosphere containing no plasma at a temperature of said substrate in which hydrogen is prevented from being activated due to heat; a source material of said second insulating film having a property that no hydrogen is generated in said atmosphere through decomposition of said source material during said thermal CVD process.
