Patent ID: 8350296

Claim:
An enhancement mode III-Nitride device comprising first and second adjacent and diverse III-Nitride layers defining a 2-DEG normally conductive layer at their interface; spaced source and drain electrodes connected to a top surface of said first III-Nitride layer; a field dielectric layer disposed between said source and drain electrodes; and a floating gate structure supported on said top surface of said first III-Nitride layer and disposed between said source and drain electrodes in a window formed in said field dielectric layer; said floating gate structure comprising a first dielectric layer fixed to said top surface of said first III-Nitride layer and a conductive floating gate disposed atop said first dielectric layer; a second dielectric layer disposed atop said conductive floating gate and a conductive control gate partially disposed atop said second dielectric layer such that a bottom surface of a portion of said conductive control gate is horizontally coplanar with a bottom surface of said conductive floating gate.
