Method for manufacturing semiconductor substrates and method for suppressing introduction of displacement to growth layer

Abstract

The problem to be solved by the present invention is to provide novel technology capable of suppressing the introduction of displacement to a growth layer. The present invention, which solves the abovementioned problem, pertains to a method for manufacturing a semiconductor substrate, the method including: a processing step for removing a portion of a base substrate and forming a pattern that includes a minor angle; and a crystal growth step for forming a growth layer on the base substrate where the patter has been formed. In addition, the present invention pertains to a method for suppressing the introduction of displacement to a growth layer, the method including a processing step for removing a portion of the base substrate and forming a pattern that includes a minor angle prior to forming the growth layer on the base substrate.
