摘要:
Provided is a simplified method of manufacturing a semiconductor device having a stress creating layer. A first conductive first impurity region is formed on a semiconductor substrate on both sides of a first gate of a first area of the semiconductor substrate, and a second conductive second impurity region is formed on the semiconductor substrate on both sides of a second gate of a second area. First and second spacers are formed on sidewalls of the first and second gates, respectively. First and second semiconductor layers are formed in portions of the semiconductor substrate so as to contact the first and second impurity regions, respectively. The second semiconductor layer is removed. First and second barrier layers are formed in the first and second contact holes of the insulation layer, respectively.
