Abstract:
1. A method of fanout redistribution of signal pads on a multilayer chip carrier, comprising: providing a layer of dielectric material having a plurality of signal pads formed thereon in a pattern of signal pads within the footprint of at least one chip to be carrier therein; providing conductive lines connected to a first set of signal pads of said plurality of signal pads near the edge of said chip footprint extending beyond the edge of said chip footprint to allow signals from said first set of signal pads to escape said chip footprint; moving a second set of signal pads of said plurality of signal pads closer to the edge of said chip footprint with at least some of said signal pads moved closer to the edge of said chip footprint having connections to signal pads on another layer of dielectric material; and moving at least some of said signal pads on said another layer of dielectric material closer to the edge of said chip footprint.
