Patent ID: 7547631

Claim:
A method of depositing a film comprising the steps of: providing a substrate in a vapor deposition reactor; conveying as a precursor an organometallic compound of the formula (R 1 YCR 2 PR 3 ) n M +m L 1 (m-n) L 2 p , wherein R 1 , R 2 and R 3 are independently chosen from H, (C 1 -C 6 )alkyl, (C 2 -C 6 )alkenyl, (C 2 -C 6 )alkynyl and aryl; Y═N or P; M=a metal; L 1 =an anionic ligand; L 2 =a neutral ligand; m=the valence of M; n=1-6; p=0-3; and wherein m>n in a gaseous form to the reactor; and depositing a film comprising the metal on the substrate.
