IPC: H01L21/31
Filed: 1989-02-20
Abstract: PURPOSE:To obtain excellent SiO2 and improve insulation characteristics by eliminating impurity of a thin film formed of TEOS by using oxygen radical produced by oxygen plasma or light. CONSTITUTION:After an SiO2 film is formed by using tetraoxisilane (TEOS), the film is exposed to the following atmosphere or irradiated with light; said atmosphere is produced by decomposing one or more gas out of O2, N2O, NO, NO2, CO, and CO2, or mixed gas of N2 and inert gas, by using plasma. For example, a first insulating film 12 is formed on a substrate 11; an aluminum wiring containing Si is patterned as a first metal wiring 13; an SiO2 film is formed as a second insulating film 14 by performing plasma decomposition of TEOS and O2 gas in a parallel flat plates type plasma CVD apparatus. Further, after the SiO2 film is deposited, it is exposed to O2 gas plasma for about 5 minutes and treated. Thereby the leak current of the SiO2 film of TEOS can be reduced.
