ABSTRACT:
A microelectronic integrated circuit includes a semiconductor substrate, and a plurality of microelectronic devices formed on the substrate. Each device has a periphery defined by a hexagon, and includes an active area formed within the periphery, a central terminal formed in a central portion of the active area, and interconnected first to third terminals formed in the active area adjacent to edges of the hexagon that are separated by other edges. First to third gates are formed between the first to third terminals respectively and the central terminal, and have contacts formed outside the active area adjacent to the other edges of the hexagon. The power supply connections to the central terminal and the first to third terminals, the conductivity type (NMOS or PMOS), and the addition of a pull-up or a pull-down resistor is selected for each device to provide a desired OR, NOR, AND or NAND function. The devices are interconnected using three direction routing based on hexagonal geometry.
