    摘要: A method for manufacturing semiconductor devices includes providing a substrate having a first region and a second region defined thereon, and a shallow trench isolation (STI) formed in between the first region and the second region, the first region comprising a first gate structure and the second region comprising a second gate structure respectively formed therein; forming a patterned protecting layer covering at least the entire STI and the second region on the substrate; forming recesses not exposing the STI in the substrate respectively at two sides of the first gate structure; and forming an epitaxial layer in the recesses respectively, the epitaxial layer filling up the recesses.
