Abstract
PURPOSE:To decrease surface leakage currents and to enhance the withstanding voltage in the reverse direction by providing a semi-insulating or highly resistive compound semiconductor layer on the surface of the active region of a compound semiconductor, and forming an insulating protecting film on said semiconductor layer. CONSTITUTION:On the surface of a semi-insulating substrate 1, a GaAS active layer 2 with the thickness of about 0.5mum and a semi-insulating or highly resistive GaAs layer 8 with the thickness of about 0.1mum are layered and deposited by a molecular beam epitaxial growing method. Mesa etching is performed, with the region including the active layer 2 having the desired shape being left. Then the part of the layer which is to become a gate part is removed by wet type or dry type etching. An Al electrode 4 which is to become Schottky gate electrode is deposited on the exposed active layer 2. Thereafter source and drain ohmic layers 6 are diffused and formed, and source and drain electrodes 5 are attached thereon, respectively. The entire surface of the substrate 1 is coated by Si3N4 film 7 by a plasma CVD method. Thus the characteristics of the FET wherein GaAs and the like are used are improved to the great extent.
