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.
