Latest Patents

Koga holds a patent for a semiconductor device and method of manufacturing thereof. This invention involves the use of a LOCOS oxide film in the main surface of a semiconductor substrate to isolate element regions. A channel cut layer formed of a P-type impurity is strategically placed under the element region. Additionally, a P.sup.+ impurity region, with a higher concentration than that of the P-type impurity in the channel cut layer, is formed directly beneath the bird's beak portion of the LOCOS oxide film. This design significantly increases the isolation breakdown voltage of an N-channel transistor region.
