Abstract:
A resin-encapsulated semiconductor device comprising:a semiconductor chip on which circuits are formed;bonding pads formed on said semiconductor chip;outer leads for connecting external terminals;inner leads connected to said outer leads;an insulating tape for electrically insulating said inner leads from said semiconductor chip, said inner leads bonded to a circuit formation surface of said semiconductor chip with said insulating tape interposed therebetween; andbonding wires electrically connecting said inner leads and bonding pads, whereina thickness of at least a portion of said inner lead in contact with said insulating tape is smaller than a thickness of said outer leada bus bar connecting two arbitrary ones of said inner leads and extended along end portions of the other inner leads, whereina thickness of at least a portion of said bus bar in contact with said insulating tape is substantially equal to a thickness of the portion of the inner lead thinner than said outer lead.
