Patent ID: 7198820

Claim:
A process for forming a carbon- and transition metal-containing film on a surface of a substrate, comprising the following process steps: (a) placing the substrate into a reaction space; (b) introducing a first chemical into the reaction space such that at least a portion of the first chemical is adsorbed onto the substrate surface; (c) after introducing the first chemical, purging the reaction space; (d) introducing a second chemical into the reaction space such that at least a portion of the second chemical reacts with the adsorbed first chemical, wherein the first chemical is one of a transition metal halide and an organometallic chemical wherein the metal portion thereof is selected from the group consisting of aluminum, gallium, and transition metal, and the second chemical is the other of said transition metal halide and said organometallic chemical wherein the metal portion thereof is selected from the group consisting of aluminum, gallium, and transition metal; (e) after the introducing said second chemical, purging the reaction space; and (f) introducing a third chemical into the reaction space, wherein further reaction takes place and the third chemical is (i) a transition metal halide when the first chemical is a transition metal halide, or (ii) an organometallic chemical wherein the metal portion thereof is selected from the group consisting of aluminum, gallium and transition metal when the first chemical is an organometallic chemical; and (g) after introducing the third chemical, purging the reaction space, whereby a carbon- and transition metal-containing film is formed on the substrate.
