  • Patent number: 9520306
    Abstract: A process for fabricating an integrated circuit package includes selectively etching a leadframe strip to define a die attach pad and a plurality of contact pads. At least one side of the die attach pad has a plurality of spaced apart pad portions. A semiconductor die is mounted to the die attach pad and wires are bonded from the semiconductor die to respective ones of the contact pads. A first surface of the leadframe strip, including the semiconductor die and wire bonds, is encapsulated in a molding material such that at least one surface of the leadframe strip is exposed. The integrated circuit package is singulated from a remainder of the leadframe strip.

  • Patent number: 7732914
    Abstract: A process for fabricating a cavity-type integrated circuit includes supporting a leadframe strip in a mold. The leadframe strip includes a die attach pad and a row of contact pads circumscribing the die attach pad. A package body is molded in the mold such that opposing surfaces of the die attach pad and of the contact pads are exposed. A semiconductor die is mounted to the die attach pad. Various ones of the contact pads are wire bonded to the semiconductor die and a lid is mounted on the package body to thereby enclose the semiconductor die and the wire bonds in a cavity of the integrated circuit package.

  • Patent number: 7449771
    Abstract: A method of fabricating an integrated circuit package. The method includes providing a first leadframe and a second leadframe, laminating the second leadframe to a portion of the first leadframe in order to create a multi-layer laminated leadframe, and mounting a semiconductor die on another portion of the first leadframe.

  • Patent number: 7410830
    Abstract: A process for fabricating a leadless plastic chip carrier includes providing a leadframe including a plurality of contacts circumscribing a void; fixing a heat sink to the contacts of the leadframe using an intermediate non-electrically conductive adhesive such that the heat sink spans the void; mounting a semiconductor die to the heat sink in the void; wire bonding ones of the contacts to the pads of the semiconductor die; encapsulating the semiconductor die and the wire bonds in a molding material and singulating the leadless plastic chip carrier.

  • Patent number: 7411289
    Abstract: A process for fabricating an integrated circuit package includes: selectively etching a leadframe strip to define a die attach pad and at least one row of contact pads; mounting a semiconductor die to one side of the leadframe strip, on the die attach pad; wire bonding the semiconductor die to ones of the contact pads; releasably clamping the leadframe strip in a mold by releasably clamping the contact pads; molding in a molding compound to cover the semiconductor die, the wire bonds and a portion of the contact pads not covered by the clamping; releasing the leadframe strip from the mold; depositing a plurality of external contacts on the one side of the leadframe strip, on the contact pads, such that the external contacts protrude from the molding compound; mounting at least one of an active and a passive component to a second side of said leadframe strip; and singulating to provide the integrated circuit package.

  • Patent number: 6585905
    Abstract: A leadless plastic chip carrier comprising a die attach pad, a semiconductor die mounted to a portion of the die attach pad and at least one row of contact pads circumscribing the die attach pad. The row of contact pads have a thickness greater than the thickness of the portion of the die attach pad. A plurality of wire bonds connect the die attach pad and the contact pads. An overmold covers the semiconductor die and all except one surface of the at least one row of contact pads and the die attach pad.
