  • Punch-through diode and method of processing the same
    Patent number: 7528459
    Abstract: A monolithically integrated punch-through diode with a Schottky-like behavior. This is achieved as a Schottky-metal area (16) is deposited onto at least part of the first p-doped well's (9) surface. The Schottky-metal area (16) and the p-doped well (9) form the metal-semiconductor-transition of a Schottky-diode. The overvoltage protection of the inventive PT-diode is improved as the forward characteristic has a voltage drop that is less than 0.5V.
