Patent ID: 7902021

Claim:
A method for making a semiconductor device, comprising: providing a semiconductor structure comprising (a) a substrate, (b) first and second gate electrodes disposed over the substrate, and (c) first and second sets of spacer structures disposed adjacent to said first and second gate electrodes, respectively, wherein each of said first and second sets of spacer structures comprises a first and second spacer disposed on opposing sides of one of said first and second gate electrodes, wherein said a topmost surface of said first set of spacer structures is coplanar with said first gate electrode, and wherein a topmost surface of said second set of spacer structures is coplanar with said second gate electrode; disposing a first layer of photoresist over the semiconductor structure such that the first set of spacer structures is exposed and the second set of spacer structures is covered; partially etching the first set of spacer structures; disposing a second layer of photoresist over the semiconductor structure such that the second set of spacer structures is exposed and the first set of spacer structures is covered; and partially etching the second set of spacer structures.
