Patent ID: 7410830

Claim:
A process for fabricating a plurality of leadless plastic chip carriers, comprising: providing a leadless plastic chip carrier strip comprising a plurality of leadframes, each leadframe comprising a plurality of contacts circumscribing a void, said contacts having an exterior portion and an interior portion, said interior portion being located between said external portion and said semiconductor die, and said interior portion having a height in a direction normal to an upper surface of said semiconductor die which is less than a height of the exterior portion; fixing a heat sink to said plurality of contacts of each leadframe using an electrically non-conductive adhesive such that each heat sink spans one of said voids; mounting a semiconductor die to each heat sink, in said void; wire bonding at least one of said plurality of contacts of each leadframe to at least one of a plurality of pads of each semiconductor die; encapsulating each semiconductor die and said wire bonds in a molding material such that an upper surface of the exterior portion of each of said contacts is exposed, and an interior portion of each of said contacts is encapsulated; and singulating said leadless plastic chip carrier strip to form a plurality of leadless plastic chip carriers.
