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.

Techniques for modular chip fabrication

Modular chip integration and operation techniques are provided. In one aspect, a method of integrating chips, chip macros or at least one chip in combination with at least one chip macro is provided. The method comprises the following steps. The chips, chip macros or at least one chip in combination with at least one chip macro are assembled on a single carrier platform. One or more signal inputs and outputs are provided to each of the chips, chip macros or at least one chip in combination with at least one chip macro. One or more power and ground inputs and outputs are provided to each of the chips, chip macros or at least one chip in combination with at least one chip macro. The power and ground inputs and outputs to one or more of the chips, chip macros or at least one chip in combination with at least one chip macro are segmented from the power and ground inputs and outputs to at least one other of the chips, chip macros or at least one chip in combination with at least one chip macro so as to form a plurality of voltage islands.

Modular chip integration techniques

An integrated circuit chip having a contact layer that includes a plurality of Vdd, Vddx, ground and I/O contacts arranged in a generally radial pattern having diagonal and major axis symmetry and generally defining four quadrants. A multilayer X-Y power grid is located beneath the contact layer. A wiring layer is interposed between the contact layer and power grid to provide a well-behaved electrical transition between the generally radial Vdd, Vddx and ground contacts and the rectangular X-Y power grid. The interposed wiring layer includes concentric square rings of Vdd, Vddx and ground wires located alternatingly with one another. The Vddx wires are discontinuous between adjacent quadrants so that the magnitude of Vddx may be different in each quadrant of the chip if desired.
