Abstract: An apparatus and method attaching a heatsink to a surface of an electronic package comprising a substrate, an integrated circuit chip attached to the surface of the substrate, an encapsulant encapsulating the integrated circuit chip and contacting at least a portion of the surface of the substrate, and an orifice formed in the top portion of the encapsulant to attach the heatsink to the surface of the electronic package. The heatsink may be attached and removed as desired to allow for package identification or rework.

Abstract: A package for mounting an integrated circuit chip to a circuit board or the like is provided. The package includes a chip carrier which has a metal substrate including first and second opposed faces. A dielectric coating is provided on at least one of the faces, which preferably is less than about 20 microns in thickness, and preferably has a dielectric constant from about 3.5 to about 4.0. Electrical circuitry is disposed on the dielectric coating, said circuitry including chip mounting pads, connection pads and circuit traces connecting the chip mounting pads to the connection pads. An IC chip is mounted by flip chip or wire bonding or adhesive connection on the face of the metal substrate which has the dielectric coating thereon. In any case, the IC chip is electrically connected to the chip mounting pads either by the solder ball or wire bond connections.

Abstract: A semiconductor device package and method includes a thick, integrated circuit chip stack having a substantially planar bottom surface with a plurality of terminals. A carrier substrate is provided, also having a substantially planar surface, and being adapted to mount the chip stack. The substrate has a plurality of terminals and may preferably be made of a metallized ceramic. The terminals of the chip stack are adapted to be connected to the terminals of the substrate. Means are provided for mounting the chip stack on the substrate, as well as means for making electrical connections between the terminals of the chip stack and the terminals of the substrate. Finally, encapsulating means are used for supporting and maintaining the chip stack mounted on the carrier substrate. J leads connect the substrate to a circuit card.
