Abstract:
1. A production method for manufacturing a plurality of chip-size packages, which comprises: defining a plurality of semiconductor chip areas on a surface of a wafer, with each of said semiconductor chip areas being produced as a semiconductor device having a plurality of electrode pads formed thereon; forming a plurality of sprout-shaped metal bumps on each of said semiconductor devices such that said respective sprout-shaped metal bumps are bonded on said electrode pads formed on a corresponding semiconductor device; forming a resin-sealing layer on the surface of said wafer such that tips of said sprout-shaped metal bumps formed on each of said semiconductor devices are projected from a top surface of said resin-sealing layer; forming a plurality of wiring patterns on the top surface of said resin-sealing layer such that each of said wiring patterns is allocated to a corresponding semiconductor device, and such that electrical connections are established between each of said wiring patterns and the tips of said sprout-shaped metal bumps formed on the corresponding semiconductor device; and forming a plurality of outer electrode terminals on each of said wiring patterns such that electrical connections are established therebetween, whereby each of said semiconductor devices is produced as a resin-sealed chip-size package on said wafer.
