Patent ID: 8022447

Claim:
A method of forming a metal-oxide semiconductor (MOS) device, the method comprising the steps of: forming a device layer on an upper surface of at least a portion of a buried oxide layer; forming a gate oxide layer on at least a portion of an upper surface of the device layer; forming a gate on at least a portion of an upper surface of the gate oxide layer, the gate being formed substantially proximate a channel defined in the device layer; doping at least a portion of the device layer not covered by the gate and the gate oxide layer with at least one impurity of a prescribed concentration level so as to form a drain therein; forming an insulator spacer on at least one sidewall of each of the gate, the gate oxide layer and the device layer; doping at least a portion of the insulator spacer with at least one impurity of a prescribed concentration level so as to form an energy filter therein; and forming a metallic source contact directly on at least a portion of an upper surface of the doped insulator spacer to enable injection of carriers from the source contact through the doped insulator spacer into the channel.
