Abstract

A semiconductor device comprises a substrate, a gate structure and a gate spacer. The substrate has a semiconductor fin protruding from a surface of the substrate. The gate structure is disposed on the semiconductor fin. The gate spacer is disposed on sidewalls of the gate structure, wherein the gate spacer comprises a first material layer and a second material layer stacked with each other and both of these two material layers are directly in contact with the gate structure.
