Patent ID: 8377511

Claim:
A method for producing silicon nitride films by chemical vapor deposition in a reaction chamber said method comprising the steps of: a) introducing a substrate into the reaction chamber, said substrate having a surface adapted to receive a silicon nitride film by chemical vapor deposition; b) introducing a pentakis(dimethylamino) disilane compound with the general formula: Si 2 (NMe 2 ) 5 Y (I) wherein Y is the amino group is NH(C n H 2n+1 ) with 0≦n≦5; c) introducing a nitrogen-containing gas selected from the group comprising of ammonia, hydrazine, alkylhydrazine compounds, and hydrogen azide compounds into the reaction chamber; and d) forming a silicon nitride film onto at least a portion of the surface of the substrate by reacting the disilane containing compound and the nitrogen-containing gas at a reaction temperature which is at least equal to the substrate surface temperature.
