Patent ID: 7192808

Claim:
A manufacturing method for a semiconductor device comprising the steps of: pressing a metal material to produce a lead frame that comprises a plurality of outer frames, a plurality of electrode supports connected with the plurality of outer frames, and a plurality of electrodes respectively supported by the plurality of electrode supports; drawing the plurality of electrode supports to be lowered in position compared with surfaces of the electrodes and at least a part of the outer frames; forming a lead frame assembly in which a semiconductor chip is electrically connected with the plurality of electrodes; enclosing the lead frame assembly within a resin package in such a way that the surfaces of the electrodes are exposed to a surface of the resin package; and cutting at least a prescribed part of the electrode supports so as to separate the plurality of electrodes from each other, wherein the plurality of electrode supports and the plurality of electrodes are within an area defined by outer frame, said outer frame being smaller than said semiconductor chip.
