Abstract:
A method for forming a three-component nitride film containing metal and silicon on a substrate, said method comprising:(a) preparing separate reactive gases each including at least one selected from the group consisting of a gaseous metal compound, a gaseous silicon compound and an ammonia gas under conditions such that the gaseous metal compound and the ammonia gas do not form a mixture; (b) effecting a sequential gas supply cycle of said reactive gases so that supplies of said gaseous metal compound, said gaseous silicon compound and said ammonia gas are each included at least once within one gas supply cycle under conditions such that the gaseous metal compound and the ammonia gas do not form a mixture; and (c) applying said reactive gases to said substrate by repeating said effecting at least once, thereby performing a chemical vapor deposition to form a three-component nitride film containing metal and silicon.
