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 semiconductor device fabrication method and a semiconductor layer formation method for making a semiconductor layer having excellent morphology selectively epitaxial-grow over a semiconductor, and a semiconductor device. When a recessed source/drain pMOSFET is fabricated, a gate electrode is formed over a Si substrate in which STIs are formed with a gate insulating film therebetween (step S1). After a side wall is formed (step S2), recesses are formed in portions of the Si substrate on both sides of the side wall (step S3). A SiGe layer including a lower layer portion and an upper layer portion is formed in the recesses of the Si substrate. The lower layer portion and the upper layer portion included in the SiGe layer are made to epitaxial-grow under a condition that growth selectivity of the lower layer portion with respect to the side wall and the STIs is lower than growth selectivity of the upper layer portion with respect to the side wall and the STIs (steps S4 and S5). As a result, the SiGe layer the growth selectivity of which with respect to the side wall and the like is secured and in which morphological deterioration is suppressed can be formed in the recesses of the Si substrate.
