Patent ID: 8101465

Claim:
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: forming a pair of scribing lines between said plural front electrodes apart from said region having said concentrated dislocations so as to hold said region having said concentrated dislocations therebetween; and separating said substrate and said semiconductor element layer along said scribing lines, thereby removing a portion including said region having said concentrated dislocations and ranging from said back surface to a front surface of said semiconductor element layer.
