An integrated circuit package. The package includes a substrate that has a first internal conductive bus and a second internal conductive bus that are located on a common layer of the substrate and dedicated to different power voltage levels. The busses are coupled to external lands located on a first surface of the package by vias that extend through the substrate. The first and second busses are located on a common layer of the substrate. The package contains an integrated circuit which is mounted to a heat slug that is attached to a second surface of the package. The integrated circuit is coupled to bond fingers located on a shelf of the substrate. Some of the bond fingers are connected to the internal busses by conductive strips that wrap around the edges of the shelf. Some of the vias are connected to a whole group of external lands. Grouping the lands to a single via reduces the number of vias on the second surface of the package. The reduction in vias allows additional capacitors to be mounted to the second surface of the package.

Integrated circuit package

Integrated circuit package which contains two in plane voltage busses

An integrated circuit package which contains an integrated circuit. The internal integrated circuit is coupled to external lands located on a first outer surface of the package by a plurality of vias. The vias extend through the package from the first outer surface to an opposite second outer surface. The package has a plurality of devices such as capacitors that are mounted to the second outer surface. Some of the vias are connected to a whole group of external lands. Grouping the lands to a single via reduces the number of vias on the second surface of the package. The reduction in vias allows additional capacitors to be mounted to the second surface of the package.

A method for plating an integrated circuit package. The method includes constructing a package which has a plurality of internal bond fingers that are subsequently coupled to an integrated circuit. The package contains a plurality of vias that are electrically connected to the bond fingers. The vias are also coupled to a layer of metallization that extends across an outer surface of the package. The meallization layer is used as a plating bar to plate the internal bond fingers. After plating the meallization layer is etched from the surface of the package.
