Abstract
A monolithically integrated logic circuit is provided that is programmed by an optical input. A plurality of input/output pads are provided on a semiconductor substrate having a planar surface. A plurality of semiconductor devices and a plurality of light sensitive devices are formed with selected patterns in the surface. At least one metallic layer is formed on the substrate for coupling selected ones of the semiconductor devices, light sensitive devices, and input/output pads for forming a logic circuit, wherein an output of the logic circuit is determined by programming selected ones of the plurality of light sensitive devices by applying light thereto.
