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 10):
The semiconductor device of  claim 9 , wherein:\n the first work function metal defines a first recess; the second work function metal defines a second recess; the third work function metal defines a third recess; a first portion of the first fill metal is located within the first recess but a second portion of the first fill metal is located outside the first recess; a first portion of the second fill metal is located within the second recess but a second portion of the second fill metal is located outside the second recess; and an entire portion of the third fill metal is located within the third recess.
