Patent ID: 8288237

Claim:
A method of fabricating a semiconductor device including a TiC metal compound comprising: positioning a semiconductor substrate in a reactor chamber, wherein an interfacial layer comprised of SiO 2 is present on the substrate and a high-k dielectric layer is present on the interfacial layer; providing a Ti target and an atmosphere that comprises Ar and a carbon (C) source that is diluted with He; sputtering a TiC film on the high-k dielectric layer from said Ti target in said atmosphere; and patterning the TiC film and the high-k dielectric layer to provide a gate structure, wherein the TiC film provides a gate conductor of a p-type semiconductor structure having interface states below 1Ã—10 11 charges/cm 2 , and having an inversion layer thickness of about 14 â„« or less.
