Abstract:
First, second, and third trenches are formed in a layer over a substrate. The third trench is substantially wider than the first and second trenches. The first, second, and third trenches are partially filled with a first conductive material. A first anti-reflective material is coated over the first, second, and third trenches. The first anti-reflective material has a first surface topography variation. A first etch-back process is performed to partially remove the first anti-reflective material. Thereafter, a second anti-reflective material is coated over the first anti-reflective material. The second anti-reflective material has a second surface topography variation that is smaller than the first surface topography variation. A second etch-back process is performed to at least partially remove the second anti-reflective material in the first and second trenches. Thereafter, the first conductive material is partially removed in the first and second trenches.

Claim (Index 8):
A semiconductor device, comprising:\n a first gate dielectric located over a substrate; a second gate dielectric located over the substrate, wherein the second gate dielectric is spaced apart from the first gate dielectric; a third gate dielectric located over the substrate, wherein the third gate dielectric is spaced apart from the first gate dielectric or the second gate dielectric; a first work function metal located over the first gate dielectric; a second work function metal located over the second gate dielectric; and a third work function metal located over the third gate dielectric, wherein the third work function metal is at least multiple times taller and wider than both the first work function metal and the second work function metal.
