Patent ID: 7981735

Claim:
A method of manufacturing a Schottky barrier tunnel transistor, the method comprising the steps of: (a) forming a semiconductor channel layer on an insulating substrate; (b) forming a dummy gate on the semiconductor channel layer, wherein the forming of the dummy gate on the semiconductor channel layer further comprises the steps of: forming an oxide layer on the semiconductor channel layer; and forming the dummy gate using polysilicon or silicon nitride on the oxide layer; (c) forming a source and a drain at both sides of the dummy gate on the insulating substrate; (d) forming a reaction blocking layer on an upper surface of the resultant of step (c) to cover a surface of the source and the drain; coating the reaction blocking layer with Hydrogen Silsesquioxane (HSQ); and removing the dummy gate by an etching process; (e) forming an insulating layer on a sidewall from which the dummy gate is removed; and (f) forming an actual gate in a space from which the dummy gate is removed, thereby forming said Schottky barrier tunnel transistor.
