Abstract:
1. A method of fabricating a semiconductor device with a back electrode, the method comprising steps of: forming a semiconductor element layer on a front surface of a substrate provided with a region having concentrated dislocations at least on part of a back surface of said substrate; after said step of forming said semiconductor element layer, forming plural front electrodes to be in contact with regions of a front surface of said semiconductor element layer corresponding to each semiconductor device, after said step of forming said plural front electrodes, reducing a thickness of said substrate; after said step of reducing said thickness of said substrate, forming said back electrode to be in contact with said back surface of said substrate; and removing said region having said concentrated dislocations after said step of forming said back electrode, wherein said step of removing said region having said concentrated dislocations includes the steps of:
