Abstract:
A method for forming an insulation film on a semiconductor substrate by plasma reaction, comprising the steps of:vaporizing a silicon-containing hydrocarbon compound to provide a source gas; introducing the source gas into a reaction space for plasma CVD processing wherein a semiconductor substrate is placed; optionally introducing an additive gas selected from the group consisting of a carrier gas, an oxidizing gas, and a plasma stabilizing gas, said source gas and said additive gas constituting a reaction gas; and forming an insulation film on the semiconductor substrate by activating plasma polymerization reaction at a temperature of about âˆ’50Â° C. to about 100Â° C. in the reaction space, wherein the plasma polymerization reaction is activated while controlling the flow of the reaction gas to lengthen a residence time, Rt, of the reaction gas in the reaction space, wherein 100 msec&lE;Rt, Rt[s]=9.42Ã—107(PrÂ·Ts/PsÂ·Tr)rw2d/F wherein: Pr: reaction space pressure (Pa) Ps: standard atmospheric pressure (Pa) Tr: average temperature of the reaction (K) Ts: standard temperature (K) rw: radius of the silicon substrate (m) d: space between the silicon substrate and the upper electrode (m) F: total flow volume of the reaction gas (sccm).
