Method for the formation of semiconductor layer

摘要

A method for the formation of a semiconductor layer by which a defect density of structural defects, particularly a dislocation density of threading dislocations in the resulting semiconductor layer can be remarkably reduced, so that hours of work can be shortened as well as a manufacturing cost can be reduced without requiring any complicated process comprises supplying a structural defect suppressing material for suppressing structural defects in the semiconductor layer onto a surface of the layer of a material from which the semiconductor layer is to be formed. <IMAGE> <IMAGE> <IMAGE> <IMAGE>
