Abstract
A gate structure which includes a semiconductor substrate having a channel region, a gate insulator adjacent the channel region of the semiconductor substrate and a conductible gate adjacent the gate insulator. A primary insulation layer is adjacent the semiconductor substrate, the primary insulation layer having an opening where the gate insulator contacts the semiconductor substrate and an isolation dielectric layer adjacent the primary insulation layer, the isolation dielectric layer having an opening where the conductible gate is located and the isolation dielectric layer having a silicon oxynitride material.
