Abstract:
1. A manufacturing method of a semiconductor device, the method comprising: preparing a metal plate having a plurality of projection electrodes in each of a plurality of semiconductor device formation areas; providing an adhesive material that projects further than top surfaces of the projection electrodes in an area of each semiconductor device formation area of the metal plate in which the projection electrodes are not formed; aligning the projection electrodes of each of the semiconductor formation areas to correspond to external connection electrodes of semiconductor constructions, and arranging each semiconductor construction separately on the projection electrodes in the semiconductor device formation areas; arranging an insulating layer formation sheet on the metal plate, the insulating layer formation sheet having openings that accommodate the semiconductor constructions; joining the metal plate and the insulating layer formation sheet by heat pressing the metal plate and the insulating layer formation sheet; patterning the metal plate and forming a plurality of upper layer wirings that connect to at least one of the projection electrodes; and acquiring a plurality of semiconductor devices which contain at least one semiconductor construction by cutting the insulating layer formation sheet.
