Abstract:
A method for manufacturing a semiconductor device comprising:preparing a wafer having a surface on which there are several semiconductor elements with corresponding electrode pads exposed on the wafer surface; forming wiring for electrically connecting each above-mentioned electrode pad to a corresponding one of plurality of external terminals; forming conductive supports at each point of the above-mentioned wiring where the above-mentioned external terminals are to be connected; forming a groove in the surface of the above-mentioned wafer along boundary lines of the above-mentioned semiconductor elements, exposing at least said groove, which has an opening width that is wider than a width of a dicing cut, and end surfaces of the above-mentioned conductive supports, covering the surface of the above-mentioned wafer with a resin; arranging the above-mentioned external terminals on the end surfaces of the above-mentioned exposed conductive supports; and sawing the above-mentioned wafer along the boundary lines of the above-mentioned semiconductor elements, wherein a side wall opposite the above-mentioned groove is inclined at a prescribed angle to a line perpendicular to the surface of the above-mentioned wafer.
