    摘要: A method of manufacturing a semiconductor device includes forming a conductive layer over a semiconductor substrate, selectively removing the conductive layer for forming a resistance element and a gate electrode, forming sidewall spacers over sidewalls of the remaining conductive layer, forming a first insulating film containing a nitrogen over the semiconductor substrate having the sidewall spacers, implanting ions in the semiconductor substrate through the first insulating film, forming a second insulating film containing a nitrogen over the first insulating film after implanting ions in the semiconductor substrate through the first insulating film, and selectively removing the first and the second insulating film such that at least a part of the first and the second insulating films is remained over the semiconductor substrate and over the conductive layer.

    摘要: A first p-type SiGe mixed crystal layer is formed by an epitaxial growth method in a trench, and a second p-type SiGe mixed crystal layer is formed. On the second SiGe mixed crystal layer, a third p-type SiGe mixed crystal layer is formed. The height of an uppermost surface of the first SiGe mixed crystal layer from the bottom of the trench is lower than the depth of the trench with the surface of the silicon substrate being the standard. The height of an uppermost surface of the second SiGe mixed crystal layer from the bottom of the trench is higher than the depth of the trench with the surface of the silicon substrate being the standard. Ge concentrations in the first and third SiGe mixed crystal layers are lower than a Ge concentration in the second SiGe mixed crystal layer.
