Silicon nitride deposition method

Abstract

A silicon nitride deposition method includes providing a substrate surface including one or more component surfaces. At least a monolayer of silicon is predeposited on the one or more component surfaces of the substrate surface resulting in a substantially native oxide free uniform predeposited silicon substrate surface. Thereafter, a silicon nitride layer is deposited on the predeposited silicon substrate surface after the silicon predeposition. Further, another silicon nitride deposition method includes providing a silicon based substrate surface. The substrate surface is nitridated in an atmosphere of dimethylhydrazine, and thereafter, a silicon nitride layer is deposited on the nitridated surface. The nitridation of the substrate surface results in a thickness less than three monolayers of silicon nitride.
