Abstract:
A semiconductor device, comprising:a metal circuit strip having a through hole formed therein;an insulating layer disposed on the metal circuit strip and having a through hole disposed in registration with the through hole of said circuit strip;a plurality of separated projecting patterns formed on the insulating layer and disposed in an array about a periphery of the through hole of said insulating layer;a semiconductor element disposed below said circuit strip and fixedly joined to the circuit strip, so that the insulating layer is sandwiched between the projecting patterns and the metal circuit strip, and the metal circuit strip is sandwiched between the insulating layer and the semiconductor element;a plurality of pads on the semiconductor element, said pads being in registration with the through hole of said circuit strip and the through hole of said insulating layer so as to be accessible through the respective through holes;a plurality of wires, each wire being electrically connected between a respective pad and a respective corresponding projecting pattern on the circuit strip; anda resin material sealing the wires, whereby said projecting patterns project outward beyond an outer surface of said insulating layer so as to provide an exposed surface that is electrically couplable to a circuit board.
