UNIFORM INTEGRATED CIRCUIT MODULUS,
Abstract
A general purpose design for an integrated circuit module is described. Depending on the connection pattern with its substrate, the circuit can perform a variety of logic and circuit functions. The active and substrate portions are shown. The Roman numerals indicate inputs and arabic numerals the outputs. While p-n-p triodes are shown for simplicity, FET's or MOSFET's are proposed for actual use. The transistor matrix is composed of identical OR-NOT-AND elements, each of which realizes a given operation. Here x is an input variable, i.e., x equals 1 when feed voltage is applied; otherwise x equals O. An example is given of the module connections required to obtain a one-bit adder with two inputs. The proposed matrix needs less commutations than would usual OR-NOT elements with three inputs, hence is theoretically more reliable in terms of fewer circuit connections. A module as a memory element is shown, where for example a positive input pulse at 1 or 1' will switch off and on; the reverse occurs with the signal applied to O or O'. The circuitry is developed on Si thin film, with SiO insulating layers where required. A ceramic substrate is used. Module leads are attached by thermal compression, and the entire assembly is hermetically sealed in a container. (Author)
