Abstract
A method of manufacturing a MOS transistor, comprising the steps of providing a semiconductor substrate, forming a gate structure on the semiconductor substrate, performing an implantation to form two implanted regions in the semiconductor substrate respectively adjacent to the gate structure, performing an etching process to remove each implanted region and form a trench, and performing a selective epitaxial growth to fill epitaxial crystal into the trenches, thereby forming a source/drain of the MOS transistor.
