    摘要： In an optimum design method comprising a first solution determining step of solving an optimization problem of a first evaluation function for a state variable vector with a design variable vector being as a parameter, and a second solution determining step of solving an optimization problem of a second evaluation function for the design variable vector and the state variable vector thus obtained, the second solution determining step includes the steps of computing a gradient vector of the second evaluation function for the design variable vector, computing a first coefficient based on a value of a norm of the gradient vector, computing a search vector based on the first coefficient, computing a second coefficient, and updating the design variable vector based on the second coefficient. The second coefficient computing step includes the first solution determining step, the first solution determining step is executed as an iterative method based on the gradient vector, and the state variable vector is not initialized during iteration. The optimum design method is precisely adaptable for structural changes.

    摘要： On an Si substrate 1, a buffer layer 2, a SiGe layer 3, and an Si cap layer 4 are formed. A mask is formed on the substrate, and then the substrate is patterned. In this manner, a trench 7a is formed so as to reach the Si substrate 1 and have the side faces of the SiGe layer 3 exposed. Then, the surface of the trench 7a is subjected to heat treatment for one hour at 750° C. so that Ge contained in a surface portion of the SiGe layer 3 is evaporated. Thus, a Ge evaporated portion 8 having a lower Ge content than that of other part of the SiGe layer 3 is formed in part of the SiGe layer 3 exposed at part of the trench 7a. Thereafter, the walls of the trench 7a are oxidized.
