Method of manufacturing a semiconductor device by monolithically forming a sealing resin for sealing a chip and a reinforcing frame by transfer molding

A method of manufacturing a semiconductor device comprising the steps of:

• providing a semiconductor chip having a main surface and a plurality of electrodes on the main surface;
• providing a tape base material having a device hole and a plurality of leads, wherein one end of the leads is extended inside the device hole and a part of the other end of the leads forms lands for connecting bump electrodes;
• arranging a semiconductor chip in the device hole of the tape base material and electrically connecting the semiconductor chip and the one end of the lead;
• and
• monolithically forming a sealing resin for sealing the semiconductor chip and a reinforcing frame surrounding the periphery of the sealing resin by transfer molding with fixing the tape base material in an area between the semiconductor chip and the reinforcing frame by a lower mold and a projection of an upper mold.
