Patent ID: 7344754

Claim:
A film formation method, comprising the steps of: (a) introducing one of an organic titanium gas and a boron compound gas into a space near a silicon oxide film formed on a surface of a substrate to be processed, and plasma-exciting the one of the organic titanium gas and the boron compound gas; and (b) introducing a gaseous phase material including a metal carbonyl compound into the space on the silicon oxide film formed on the surface of the substrate to be processed, and depositing a metal film on the silicon oxide film after said step (a), wherein said step (a) forms a nucleus including one of titanium and boron on the silicon oxide film formed on the surface of the substrate to be processed, the metal film is in direct physical contact with the silicon oxide film, and wherein at least one gas selected from the group consisting of TDEAT (Ti[N(C 2 H 5 ) 2 ] 4 ), TDMAT (Ti[N(CH 3 ) 2 ] 4 ), BF 3 , and B(C 2 H 5 ) 3 , is introduced into the space in (a).
