Abstract

A method for fabricating a semiconductor device includes the steps of forming a gate structure on a substrate, forming recesses adjacent to two sides of the gate structure, forming a buffer layer in the recesses, forming a first linear bulk layer on the buffer layer, forming a second linear bulk layer on the first linear bulk layer, forming a bulk layer on the second linear bulk layer, and forming a cap layer on the bulk layer.
