Title: Norihisa Fujii: Innovator in Semiconductor Technology
Introduction
Norihisa Fujii is a prominent inventor based in Fukuyama, Japan. He has made significant contributions to the field of semiconductor technology, holding two patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
Fujii's latest patents include a nitride semiconductor device and a heterojunction field effect transistor. The nitride semiconductor device features a second insulating film that covers at least a drain electrode and incorporates a thermal stress reducer. This reducer minimizes thermal stress generated between the drain electrode and the second insulating film during load shorts. The thermal stress reducer is designed as a drain field plate portion, extending from the upper part of the drain electrode toward the source electrode.
The heterojunction field effect transistor includes a first contact portion and a second contact portion. Notably, the length of the first contact portion is shorter than that of the source electrodes, while the second contact portion is shorter than the drain electrodes. This design ensures that the distance from the ends of the second contact portion to the ends of the drain electrode is greater than the distance from the ends of the first contact portion to the ends of the source electrode.
