Abstract:
1. A method for the deposition of a dielectric film, comprising: forming silicon nitride on a surface of a substrate within a reaction chamber; oxidizing the silicon nitride on the surface of the substrate, wherein oxidizing the silicon nitride further comprises maintaining a substrate surface temperature of about 800° C. to about 1,100° C.; exposing the oxidized silicon nitride on the surface of the substrate to a hydrogen-free nitrogen precursor in a plasma, wherein the substrate is heated to a temperature within a range from about 20° C. to about 500° C. during the exposing of the oxidized silicon nitride on the surface of the substrate to the hydrogen-free nitrogen precursor to enhance the amount of nitrogen in the oxidized silicon nitride on the surface of the substrate; and annealing the substrate.
