Abstract:
A film-forming method for forming a deposited film on a substrate arranged in a film-forming chamber employing plasma generated by a raw material gas in said film-forming chamber, said film-forming chamber comprising (i) a deposition preventive member arranged in said film-forming chamber such that said deposition preventive member prevents a film from depositing on an inner wall face of said film-forming chamber during the formation of said deposited film on said substrate and (ii) a heating means and (iii) a cooling means which are alternately arranged on a face side of said deposition preventive member (i) opposed to said inner wall face of said film-forming chamber; said method comprising the steps of:(a) evacuating the inside of said film-forming chamber and subjecting said deposition preventive member to heat treatment by heating said deposition preventive member by means of said heating means prior to commencing formation of said deposited film, and(b) forming said deposited film on said substrate maintained at a desired temperature while cooling said deposition preventive member by said cooling means to prevent said deposition preventive member from releasing unnecessary components contained in said deposition preventive member due to heat radiated from said substrate and said plasma.
