Patent ID: 7514335

Claim:
A method of manufacturing a semiconductor device, comprising: providing a base plate having an adhesive layer on a surface thereof; mounting a plurality of semiconductor chips each having a plurality of connection pads formed on an upper surface thereof to the base plate via the adhesive layer, the plural semiconductor chips being mounted apart from each other; forming an insulating film on an upper surface of the base plate including the upper surfaces of the semiconductor chips such that the insulating film has a flat surface; forming a plurality of pairs of re-wirings on the insulating film, each of the re-wirings being connected to a connection pad of any of the semiconductor chips and at least some of the re-wirings having pad portions arranged in a region of the insulating film formed on the periphery of the semiconductor chip connected to the connection pad; cutting the insulating film between the adjacent semiconductor chips so as to obtain a plurality of semiconductor devices each comprising at least one semiconductor chip, the insulating film formed on the periphery of the semiconductor chip, and the re-wiring having a pad portion arranged in the region of the insulating film; and removing the base plate from the semiconductor chip and the insulating film.
