Patent ID: 7098528

Claim:
An embedded redistribution interposer for providing footprint compatible chip package migration in which a die designed for mounting into a chip package with footprint compatibility with a first type of silicon platform is originally implemented using the first type of silicon platform and is subsequently redesigned for a second type of silicon platform, resulting in a redesigned die being a different size than the original die and no longer compatible for mounting in the chip package, the embedded redistribution interposer comprising: an interposer substrate having top and bottom sides, wherein the redesigned die for the second type of silicon platform is mounted on the top side of the interposer substrate, and the bottom side of the interposer substrate is mounted to a substrate of the chip package with footprint compatibility with the first type of silicon platform; a plurality of bond pads; a first set of electrical connections coupled between the redesigned die and the plurality of bond pads to connect the redesigned die to the redistribution interposer; and a second set of electrical connections coupled between the plurality of bond pads and the chin package substrate to connect the redistribution interposer to the chip package, wherein signals from the redesigned die are redistributed from the redesigned die such that die fan-out is increased without violating assembly rules, thereby eliminating the need to redesign the chip package to accommodate the redesigned die.
