Abstract:
1. A method of forming a silicon nitride film comprising: heating a substrate to a temperature of 550° C. or less; thermally decomposing a silicon/nitrogen containing source gas or a silicon containing source gas and a nitrogen containing source gas using only thermal energy to form a silicon nitride film on said substrate while heating said substrate to a temperature of 550° C. or less, wherein said silicon/nitrogen containing source gas or said silicon containing source gas includes a first silicon atom bonded to a second silicon atom by a single bond, wherein a chlorine (Cl) atom or a nitrogen (N) atom is bonded to said first silicon atom, and wherein a chlorine atom or a nitrogen atom is bonded to said second silicon atom; and treating said silicon nitride film with hydrogen radicals.
