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 13):
The semiconductor device of  claim 11 , wherein the first height is greater than the second height or less than the second height, and wherein the first height differs from the second height by no more than 60%.
