Abstract:
A method of manufacturing a semiconductor device, comprising:a step of providing a substrate with an adhesive material provided on one surface thereof; a step of carrying out punching from the side of said substrate on which said adhesive material is provided, and in the direction of the opposite side thereof, whereby penetrating holes are formed and a part of said adhesive material is drawn into said penetrating holes; a step of adhering a conductive member over a particular region on said one surface including said penetrating holes on said substrate through said adhesive material; a step of providing a material for forming external electrodes on said conductive member, and forming external electrodes through said penetrating holes and the inner side of said part of adhesive material drawn into the penetrating holes to project from the surface opposite to the surface of said substrate on which said conductive member is formed; and a step of electrically connecting electrodes of a semiconductor chip to said conductive member.
