Latest Patents
One of Yasoo Harada's latest patents is for a semiconductor device with a floating quantum box. This invention features an undoped Al.sub.0.22 Ga.sub.0.78 As spacer layer and an N-Al.sub.0.22 Ga.sub.0.78 As electron-supplying layer, both of which have large forbidden bandgaps. The device is designed to operate on an undoped GaAs buffer layer with a smaller forbidden bandgap, incorporating InAs quantum boxes that are approximately 150 .ANG. in size and 40 .ANG. in height. When a predetermined drain voltage is applied, electrons accumulate in the InAs quantum boxes, resulting in minimal drain current flow. Another notable patent is for a field effect semiconductor device with a low-noise drift layer. This device includes an undoped In.sub.0.2 Ga.sub.0.8 As first low-noise drift layer, followed by an undoped In.sub.x Ga.sub.1-x As second low-noise drift layer, and an n-type GaAs high-power drift layer. The high-power drift layer consists of two sections, one doped with n-type carriers at high concentration and the other at low concentration.
