Patent ID: 7045395

Claim:
A method for fabricating an integrated circuit package, comprising the steps of: (1) preparing a substrate having a front surface and a back surface, and which is predefined with a plurality of package sites; (2) preparing a heat-spreader frame including a plurality of integrally-formed heat spreaders having a front surface and a back surface, each heat spreader having a protruded block formed on the front surface of the heat-spreader frame corresponding to one of the predefined package sites on the substrate, wherein the heat spreader frame is a non-legged type; (3) bonding and electrically-coupling a plurality of semiconductor chips to respective package sites on the front surface of the substrate; (4) assembling the heat-spreader frame to the substrate in such a manner that each heat spreader having the protruded block is positioned proximate to one of the semiconductor chips on the substrate and free of contact with the one of the semiconductor chips; (5) performing an encapsulation process to form an encapsulation body which fully encapsulates the semiconductor chips and the front surface of the heat-spreader frame; (6) performing a ball-implantation process to implant a plurality of solder balls on the back surface of the substrate; and (7) singulating through the encapsulation body to cut apart the plurality of package sites on the substrate so as to form a plurality of individual integrated circuit packages.
