  • Patent number: 6492253
    Abstract: A programmable substrate and a method of making a programmable substrate for use with array-type packages, including Ball Grid Arrays(BGA), Pin Grid Arrays (PGA) and Column Grid Arrays (CGA) includes a nonconductive programmable substrate with a cavity in the top of the substrate. The cavity is sized to receive an integrated circuit (IC) die. An array of electrically conductive vias pass through the substrate. A plurality of electrical traces are formed on the top of the substrate. The traces extend radially from an edge of the die cavity to the periphery of the substrate so as to pass between and near the vias. Each trace is electrically connected to a pad of the IC die by a wire bond. Each via is connected on a bottom surface of the substrate to a solder ball, pin, or other means for electrically and mechanically attaching the substrate to a printed circuit board. The traces are programmably connected to a selected via, e.g.

  • Patent number: 6297550
    Abstract: A semiconductor package (100) includes a bondable aluminum heatspreader (130) made from anodized aluminum, thereby forming an anodization layer (132) on the surface of the heatspreader. Portions of the anodization layer are removed, e.g., by grinding, in order to provide an attachment area (124) to which a wire (122) or beam may be bonded in order to electrically connect the heatspreader to a desired voltage potential, such as a ground potential or a positive or negative potential. The heatspreader is thermally bonded to a semiconductor die (102) housed within the package. The anodized aluminum heatspreader thus not only removes and dissipates heat from the semiconductor die, but also functions as a voltage or ground plane within the semiconductor package.
