Patent ID: 7001784

Claim:
A method of fabricating final spacers each having a target width, comprising the steps of: providing a structure having a gate electrode portion formed thereover; the gate electrode portion having a top and opposing side walls; forming initial spacers over the opposing side walls of the gate electrode portion; the initial spacers each having an initial width that is less than the target width, the initial width and the target width being defined by the initial spacers and the final spacers extending along the structure away from the gate electrode portion, respectively; determining the difference between the initial width of the initial spacers and the target width; forming a second spacerlayer upon the initial spacers and the structure, the second spacer layer having a thickness that is equal to the determined difference between the initial width of the initial spacers and the target width; and etching at least the second spacer layer from over the initial spacers and the structure leaving second spacer layer portions extending from the initial spacers along the structure forming the final spacers.
