  • Patent number: 8274164
    Abstract: A high power surface mount package including a thick bond line of solder interposed between the die and a heatsink, and between the die and a lead frame, wherein the lead frame has the same coefficient of thermal expansion as the heatsink. In one preferred embodiment, the heatsink and the lead frame are comprised of the same material. The package can be assembled using standard automated equipment, and does not require a weight or clip to force the parts close together, which force typically reduces the solder bond line thickness. Advantageously, the thermal stresses on each side of the die are effectively balanced, allowing for a large surface area die to be packaged with conventional and less expensive materials. One type of die that benefits from the present invention can include a transient voltage suppressor, but could include other dies generating a significant amount of heat, such as those in excess of 0.200 inches square.

    Abstract: A semiconductor wafer has integrated circuits formed thereon and a top passivation layer applied. The passivation layer is patterned and selectively etched to expose contact pads on each semiconductor die. The wafer is exposed to ionized gas causing the upper surface of passivation layer to roughen and to slightly roughen the upper surface of the contact pads. The wafer is cut to form a plurality of semiconductor dies each with a roughened passivation layer. The plurality of semiconductor dies are placed on an adhesive layer and a reconstituted wafer formed. Redistribution layers are formed to complete the semiconductor package having electrical contacts for establishing electrical connections external to the semiconductor package, after which the wafer is singulated to separate the dice.
