Abstract: A method for forming a semiconductor device comprising forming a dielectric layer on an area of a silicon substrate; implanting nitrogen atoms into said dielectric layer; forming a conductive layer of polysilicon over said dielectric layer; annealing the dielectric layer to drive the nitrogen atoms to form a gate dielectric of a dielectric layer having silicon nitride layer interfaces of the dielectric layer and the silicon substrate and the polysilicon layers; and, forming a gate structure in said polysilicon layer and source/drain regions in said silicon substrate, said source/drain regions aligned with said gate structure.
