POWER DISTRIBUTION BUS FOR INTEGRATED CIRCUITS

摘要

IMPROVEMENTS RELATING TO SEMICONDUCTOR INTEGRATED CIRCUIT DEVICES A power bus element for use in large scale integrated circuits is described. Each bus element consists, for example, of a chip of silicon having two levels of metallizationthereon, one acting as an earth (or ground) return plane and the other providing power voltages. Dependent contacts on the chip make selective contact with metallization over the surface of the semiconductor wafer on which the chip is mounted. A power distribution line consists of a number of such bus elements linked together.
