SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME

Abstract:

A method for fabricating semiconductor device is disclosed. First, a substrate is provided, a gate structure is formed on the substrate, a recess is formed adjacent to the gate structure, a buffer layer is formed in the recess, and an epitaxial layer is formed on the buffer layer. Preferably, the buffer layer includes a crescent moon shape.
