Abstract:
A thin enhanced TAB BGA package having improved heat dissipation comprising:a semiconductor chip having an active side with semiconductor circuitry formed thereon, and a second side opposite from the active side;a substrate having a center opening therethrough, and first and second opposite facing substrate sides, at least the first substrate side having metallic circuitry formed thereon which circuitry has a plurality of inner leads, the inner leads having one end extending into the center opening and coupled with the semiconductor circuitry of the semiconductor chip;a plurality of solder balls attached to the second substrate side and coupled with the metallic circuitry of the substrate, the second substrate side with the solder balls facing in the same direction as the active side of the semiconductor chip; anda heat dissipating member for dissipating heat generated in the semiconductor chip and for supporting the chip and the substrate, said heat dissipating member having a center portion extending through the center opening in the substrate and adhered to the active side of the semiconductor chip, an intermediate portion adhered to the inner leads extending into the center opening and an outskirt portion adhered to the substrate, the adhering being by a non-conductive adhesive.
