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 11):
A semiconductor device, comprising:\n a first gate disposed over a substrate, wherein the first gate has a first lateral dimension, and wherein the first gate includes a first work function metal component having a first height; a second gate disposed over the substrate, wherein the second gate has a second lateral dimension, and wherein the second gate includes a second work function metal component having a second height; and a third gate disposed over the substrate, wherein the third gate has a third lateral dimension, and wherein the third gate includes a third work function metal component having a third height, wherein the third lateral dimension is greater than the first lateral dimension and the second lateral dimension, and wherein the third height is greater than the first height and the second height.
