Abstract:
A method of manufacturing a semiconductor device including a PMOS transistor and an NMOS transistor comprises the steps of:(a) providing a semiconductor substrate having a P-well region, which is to be provided with the NMOS transistor, and an N-well region, which is to be provided with the PMOS transistor; (b) forming gate electrodes on the P-well region and the N-well region; (c) applying a hard mask, which covers either the P-well region or the N-well region; (d) implanting a source and a drain in the region that is not covered by the hard mask, followed by heat activation; (e) implanting pocket implants only in the region that is not covered by the hard mask, followed by heat activation; (f) removing the hard mask.
