A MOS control diode is provided for power switching. In the MOS control diode, a switching speed is high and a reverse leakage current characteristic is improved without additionally needing processes for improving reverse recovery time by converting a power MOSFET which is a majority carrier device...http://www.google.de/patents/US6674123?utm_source=gb-gplus-sharePatent US6674123 - MOS control diode and method for manufacturing the same
