摘要: A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate, wherein the substrate comprises a gate structure thereon; forming a film stack on the substrate and covering the gate structure, wherein the film stack comprises at least an oxide layer and a nitride layer; removing a portion of the film stack for forming recesses adjacent to two sides of the gate structure and a disposable spacer on the sidewall of the gate structure; and filling the recesses with a material comprising silicon atoms for forming a faceted material layer.
