    Abstract: A main semiconductor region grown on a substrate has formed on its surface a pair of main electrodes spaced from each other, a gate electrode between the main electrodes, and a pair of diode-forming electrodes spaced farther away from the gate electrode than are the main electrodes. Making ohmic contact with the main semiconductor region, the pair of main electrodes serve both as drain or source of a HEMT switch and as cathodes of a pair of Schottky diodes integrated with the HEMT switch. Both gate electrode and diode-forming electrodes are in Schottky contact with the main semiconductor region.

    Abstract: A high electron mobility transistor is disclosed which has a main semiconductor region formed on a silicon substrate. The main semiconductor region is a lamination of a buffer layer on the substrate, an electron transit layer on the buffer layer, and an electron supply layer on the electron transit layer. A source, drain, and gate overlie the electron supply layer. Also formed on the electron supply layer is a surface-stabilizing organic semiconductor overlay which is of p conductivity type in contrast to the n type of the electron supply layer.
