A metal programmable semiconductor device is disclosed. The semiconductor device, comprises: a metal programmable logic circuit; and a plurality of fixed interconnect geometries including metal and via structures; and a plurality of selectable interconnect geometries, each said interconnect geometry capable of coupling a first of said fixed interconnects to a second of said fixed interconnects; and a binary bitstream, each bit in the bitstream assigned to one or more of said selectable interconnect geometries, wherein the binary state of a said bit specifies if said assigned one or more selectable geometries is included or excluded in the selection; and a computer aided design tool that identifies one or more logic functions and an interconnect pattern to fully program the logic circuit to a user specification by identifying the bit states of said binary bitstream; and at least one custom mask comprising a portion of said fixed interconnect geometries and a portion of the bitstream selected geometries of said one or more selectable interconnect geometries, wherein the said at least one custom mask programs the programmable circuit to the customer specification during fabrication of the semiconductor device. |
