Abstract

Abstract A large number of different types of circuits made from a single semiconductor wafer configuration by varying the manner in which connections and leads are provided to the various regions of the wafer. A plurality of different circuit elements such as transistors, diodes, resistors and capacitors, are formed in a wafer semiconductor material, preferably by diffusion into the surface of a major wafer. These elements are arranged in a pattern adjacent the major face, with each region or electrode of each element coming to the surface at this face so that electrical connection may be made thereto. An insulating coating is provided on the major face of the wafer, with holes being formed in the coating where contacts are to be made, and conductive material is preferably deposited first over the entire face of the wafer and is later removed in a selected pattern to create the interconnections between components necessary for the selected circuit.
