Patent ID: 7019351

Claim:
A method of forming a circuit device, comprising: forming a dielectric layer over a substrate; forming a metal-containing material directly on the dielectric layer, the metal-containing material being formed to a thickness of no more than about 20 Å; forming conductively-doped silicon directly on the metal-containing material; and wherein the conductively-doped silicon directly on the metal-containing material; and wherein the conductively-doped silicon is n-type doped, and wherein a work function of the conductively-doped silicon and material-containing material together is shifted relative to the work functions of the conductively-doped silicon and the metal-containing material in pure form, and is shifted from the work function of the metal-containing material in pure form, and is shifted from the work function of the metal-containing material in pure form by at least 50 millivolts.
