Patent ID: 8421241

Claim:
A semiconductor device comprising: a semiconductor chip; a lead frame, electrically coupled to the semiconductor chip, the lead frame provided with a recessed portion on a surface of the lead frame; a resin section that molds the semiconductor chip and the lead frame, the resin section provided with an opening above the recessed portion of the lead frame; a hole that penetrates through the lead frame, the hole being disposed in a part of the recessed portion and having a width that is smaller in magnitude than the width of the recessed portion wherein the sidewalls of the opening, the recessed portion and the hole are parallel, and wherein the sidewalls of the opening are formed in the resin section parallel to and outside of the sidewalls of the recessed portion and the hole, wherein the semiconductor device comprises one of a plurality of semiconductor devices electrically coupled via a conductive pin, the conductive pin being inserted through the recessed portion provided on the lead frame and the opening wherein the opening is wider than the recessed portion and the hole and the opening and the recessed portion comprises unfilled space that surrounds the conductive pin.
