Abstract

A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate having a gate structure thereon, a first spacer around the gate structure, and a contact etch stop layer (CESL) adjacent to the first spacer; forming a cap layer on the gate structure, the first spacer, and the CESL; and removing part of the cap layer for forming a second spacer adjacent to the CESL.
