SEMICONDUCTOR ELEMENT AND MANUFACTURING METHOD THEREFOR, AND SEMICONDUCTOR DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a semiconductor element which has the effect of lowering its forward voltage VF rather than raising it even if a semiconductor substrate is thick. SOLUTION: A method is for manufacturing a semiconductor element 7 which has an anode electrode 3 and a cathode electrode 4 arranged on only the surface of the semiconductor substrate 1 and a metal layer 6 as a non- electrode in ohmic-contact with the substrate 1 on the reverse surface 5 of the substrate 1, and the method is for manufacturing the semiconductor element 7 which patterns the metal layer 6, and a semiconductor device 12 which has an insulating layer 11 on the metal layer 6.
