METHOD OF CHEMICAL VAPOR DEPOSITION OF METAL FILMS

摘要

A method of producing a thick metal film on a substrate surface with a substantially smooth surface morphology and low resistivity. A substrate is exposed to a plasma. A first thin metal film is deposited on the substrate by chemical vapor deposition. The substrate with the film deposited thereon is exposed to a plasma, and a second thin metal film is deposited on top of the first film. The substrate may undergo subsequent cycles of plasma exposure and film deposition until a desired film thickness is obtained. The resulting film has a smooth surface morphology and low resistivity.
