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.

摘要： A method of fabricating a semiconductor device is disclosed that is able to suppress a short channel effect and improve carrier mobility. In the method, trenches are formed in a silicon substrate corresponding to a source region and a drain region. When epitaxially growing p-type semiconductor mixed crystal layers to fill up the trenches, the surfaces of the trenches are demarcated by facets, and extended portions of the semiconductor mixed crystal layers are formed between bottom surfaces of second side wall insulating films and a surface of the silicon substrate, and extended portion are in contact with a source extension region and a drain extension region.
