Techniques for modular chip fabrication

Techniques for modular chip fabrication are provided. In one aspect, a modular chip structure is provided. The modular chip structure comprises a substrate; a carrier platform attached to the substrate, the carrier platform comprising a plurality of conductive vias extending through the carrier platform; and a wiring layer on the carrier platform in contact with one or more of the conductive vias, wherein the wiring layer comprises one or more wiring levels and is configured to divide the carrier platform into a plurality of voltage islands; and chips, chip macros or at least one chip in combination with at least one chip macro assembled on the carrier platform.
