Abstract
A semiconductor device includes a semiconductor substrate having a surface; and a strained superlattice structure including first semiconductor layers having a first strain in a direction with respect to the semiconductor substrate and second semiconductor layers having a second strain in the same direction as and different in magnitude from the first strain, the first semiconductor layers and the second semiconductor layers being alternatingly laminated. The difference in strains between the first semiconductor layers and the second semiconductor layers is reduced, so that the crystalline quality of the strained superlattice structure is improved.
