    摘要: A semiconductor operational circuit conducts real-time analog vector operations to permit the determination of the center of gravity of an image of a moving object. The circuit employs a first processing stage utilizing CMOS source follower circuits to perform weighted linear sum operations on the analog signals. A second processing stage utilizes comparator circuitry to perform comparison operations involving data from the weighted-sum and non-weighted-sum operations. A third processing stage utilizes exclusive OR gates to provide digital data outputs based on the comparison operation results.

    摘要: A method of manufacturing a semiconductor device, and particularly a method of forming a monocrystalline film on a substrate. The method includes the step of forming a conductor layer having a step portion on the surface of a substrate. The step portion includes a lateral face which surrounds the lower surface of the step portion to form a closed loop. After the conductor layer has been formed on the surface of the substrate, a monocrystalline film is formed directly on the substrate. Specifically, the film is formed on the lower surface of the step portion, while a DC potential is applied to the conductor layer.
