Abstract:
A method of forming a semiconductor device includes forming a gate electrode on a substrate, forming a first spacer on a sidewall of the gate electrode, forming a second spacer on the first spacer, and forming a capping pattern on top surfaces of the gate electrode, the first spacer and the second spacer.
