Abstract:
1. A method of forming a microcrystalline hydrogenated silicon body on a substrate, said method comprising the steps of: flowing a chemical vapor coating gas comprising hydrogen and silicon over said substrate and exciting said coating gas with at least one pulse of electromagnetic radiation and depositing at least one film of amorphous hydrogenated silicon on said substrate; flowing a hydrogen treatment gas over said substrate and exciting said treatment gas with another at least one pulse of electromagnetic radiation to form hydrogen plasma after deposition of said at least one amorphous hydrogenated silicon film, and transforming said at least one amorphous hydrogenated silicon film with said hydrogen plasma into a film of microcrystalline hydrogenated silicon; and immediately switching said flow of said coating gas to said flow of said treatment gas to form a continuous flow of gas over said substrate.
