Claim Text:
1. A semiconductor device, comprising: a silicon substrate; a gate structure formed over the silicon substrate, wherein the gate structure includes a high-k gate dielectric, a metal gate electrode formed over the high-k gate dielectric, and first and second oxide-nitrogen-oxide (ONO) gate spacers formed on opposite sidewalls of the gate dielectric and gate electrode; first and second silicon compound components formed in the silicon substrate and on opposite sides of the gate structure, wherein one of the first and second silicon compound components has a slanted surface that borders a dielectric trench isolation structure, and wherein the other of the first and second silicon compound components has a horizontal surface substantially parallel to a surface of the silicon substrate over which the gate structure is formed; and first and second source/drain regions formed in the first and second silicon compound components, respectively.
