FIELD EFFECT TRANSISTOR, SEMICONDUCTOR SWITCH AND SEMICONDUCTOR PHASE SHIFTER

摘要

PURPOSE: To obtain a device, e.g. a semiconductor switch or a semiconductor phase shifter, in which the size is reduced while enhancing the characteristics. CONSTITUTION: An inductance or a capacitor is provided, in the form of an electrode finger 27 for inductance, between drain(D) and source(S) thus constituting an FET incorporating an inductor or a capacitor. The inductor or capacitor also serves as a part of the electrode of the FET. When this FET is employed in the constitution of a device, e.g. a semiconductor switch or a semiconductor phase shifter, a small-size device excellent in reflection characteristics can be obtained.
