  • High-gain, high-voltage transistor for linear integrated circuits
    Patent number: 4047217
    Abstract: A semiconductor structure for, and method of manufacture of, a linear integrated circuit provides the equivalent of a base function in a transistor, wherein the base function has a dual charge density, with the latter being relatively low in the lower active area of the base between PN junctions for high gain and high breakdown voltage, but high along the upper surface to prevent an unwanted inversion layer from occurring.
