Abstract:
1. A method for manufacturing a plurality of semiconductor devices each comprising a semiconductor element, an insulating tape on a surface of which a number of wiring patterns and a number of electrode pads are formed, and metal plate bonded to a reverse surface of an insulating tape by adhesive, said wiring patterns being electrically connected to electrodes of said semiconductor element, a number of solder bumps being connected to said electrode pads, at least a circuit formed surface of said semiconductor element being coated with a sealing resin, said method comprising bonding said insulating tape to a lead frame, loading a number of said semiconductor elements onto said lead frame, electrically connecting said wiring patterns with the electrodes of said semiconductor elements, sealing the circuit formed surfaces of said semiconductor elements with said sealing resin, and cutting said lead frame to simultaneously form said metal plates corresponding to said semiconductor elements, wherein at least a part of an outer periphery of said metal plate extends beyond an outer periphery of said insulating tape.
