Abstract
According to a semiconductor substrate (), a space (A) between a plurality of Si thin film (), which are provide apart from one another on the insulating substrate (), is (I) larger than a difference between elongation of part of the insulating substrate which part corresponds to the space (A) and elongation of each of Si wafers () when a change is made from room temperature to 600° C. and (II) smaller than 5 mm. This causes an increase in a region of each of a plurality of semiconductor thin films which region has a uniform thickness, and therefore prevents transferred semiconductor layers and the insulating substrate from being fractured or chipped.
