Latest Patents

One of his latest patents is the "Modulation doped GaAs/AlGaAs field effect transistor." This invention aims to realize a depletion-mode modulation-doped field-effect transistor with a high gate-length to depletion-depth ratio. It is designed to provide high power gain at millimeter-wave frequencies by utilizing an ohmic gate or a heterojunction gate on the n-AlGaAs/GaAs layered structure. This innovation is particularly beneficial for analog signal amplifying circuits, contrasting with the enhancement-mode devices typically used for digital circuits. The need for this change arises from the limitations of Schottky-barrier gate structures, which naturally operate in enhancement mode.

Another significant patent is the "Built-in notched channel MOS-FET triodes for high frequency application." This novel device features an effective channel length smaller than that of conventional built-in channel MOS-FET devices. It consists of an insulating substrate and a semiconductor layer with two n.sup.+ -type regions separated by an n-type region. The design includes insulation over the semiconductor region, openings for metal contacts, and a notch in the n-type semiconductor region, enhancing its functionality for high-frequency applications.
