Disclosed is an integrated circuit comprising a plurality of cores attached to at least one transmitter and receiver, an optical transmission network embedded within the wire levels of the integrated circuit, and wherein the transmitter and receivers send and receive data on the network. Also disclosed is a method of transmitting signals within an integrated circuit comprising an integrated circuit comprising a plurality of cores and optical paths, selecting an optical path from the plurality of optical paths for transmitting data, and transmitting the data on the selected optical path. Also disclosed is an integrated circuit comprising an optical transmission network, a plurality of cores, and a plurality of controllers, all three being operatively attached to each other.

A method for automatically wiring (i.e., routing) an integrated circuit chip after completing the placement of cells on the chip is described. The method employs a maze routing such that the spacing between the routed wires is increased, while at the same time maintaining control over the total wiring length. The maze routing herein described is modified to improve chip yield, reduce wiring capacitance, limit power consumption and coupled signal noise, all of which are achieved by increasing wire-to-wire spacings.

Rotary signal coupling in in-situ monitoring of a chemical-mechanical polishing process. A sensor fixed to a rotatable wafer carrier for creating a signal responsive to the chemical mechanical polishing process is coupled to a bottom half of a rotary transformer fixed to a rotating portion of the polisher. A top half of the rotary transformer, coupled to the bottom half of the rotary transformer, is fixed to a stationary portion of the polisher. The signal from the sensor is thus coupled through the rotary transformer to a process monitor.
