Abstract:
1. A method of forming a dielectric film having Si—C bonds and/or Si—N bonds on a semiconductor substrate by cyclic deposition, which comprises: (i) conducting one or more cycles of cyclic deposition in a reaction space w herein a semiconductor substrate is placed, each cycle having a period supplying a Si-containing precursor and a reactant gas simultaneously, without RF power, and a period applying a pulse of RF power to the reaction space while supplying the reactant gas; and (ii) before or after step (i), but not during step (i), applying a pulse of RF power to the reaction space while supplying a rare gas and a treatment gas without supplying the Si-containing precursor, whereby a dielectric film having Si—C bonds, Si—N bonds, or Si—C and Si—N bonds is formed on the semiconductor substrate.
