Abstract

Disclosed is a semiconductor device capable of suppressing the generation of dislocations due to the difference in lattice constant by insertion of one or more defect type compound layers in a semiconductor layered structure. The strain generated by the mismatch of the lattice is relaxed by a large amount of vacancies contained in the defect type compound layer, to suppress the generation and the propagation of dislocations, thus inexpensively fabricating a semiconductor device with less deterioration of the characteristics due to defects with good repeatability.
