Abstract
A method for forming a semiconductor device includes providing a substrate having at least a gate positioned thereon, forming at least a recess in the substrate adjacent to the gate, performing a first selective epitaxial growth (SEG) process to form a first epitaxial layer in the recess, performing an etching process to remove a portion of the first epitaxial layer to expose the substrate, and performing a second SEG process to form a second epitaxial layer on the first epitaxial layer.
