ABSTRACT:
A method of manufacturing a semiconductor device comprises a step of forming a through-hole in a semiconductor chip having an electrode and forming a conductive layer on a region comprising an inner side of the through-hole. An intermediate portion of the through-hole is formed to be larger than an edge portion thereof, and the conductive layer is formed by electroless plating.
