Abstract
A method for forming a film having a low dielectric constant and high mechanical hardness on a semiconductor substrate by plasma reaction includes the steps of: (i) introducing a silicon-containing hydrocarbon gas as a source gas into a reaction space for plasma CVD processing wherein a semiconductor substrate is placed; and (ii) applying radio-frequency (RF) power of 1,000 W or higher to the reaction space while maintaining a pressure of the reaction space at 100 Pa or higher to activate plasma polymerization reaction in the reaction space, thereby forming a thin film on the semiconductor substrate.
