摘要： Provided are a transistor of a semiconductor device and method of fabricating the same. The transistor includes: an epitaxy substrate disposed on a semi-insulating substrate and having a buffer layer, a first Si planar doping layer, a first conductive layer, a second Si planar doping layer, and a second conductive layer, which are sequentially stacked, the second Si planar doping layer having a doping concentration different from that of the first Si planar doping layer; a source electrode and a drain electrode diffusing into the first Si planar doping layer to a predetermined depth and disposed on both sides of the second conductive layer to form an ohmic contact; and a gate electrode disposed on the second conductive layer between the source and drain electrodes and being in contact with the second conductive layer. In this structure, both isolation and switching speed of the transistor can be increased. Also, the maximum voltage limit applied to the transistor is increased due to increases in gate turn-on voltage and threshold voltage and a reduction in parallel conduction element. As a result, the power handling capability of the transistor can be improved, thus improving a high-power low-distortion characteristic and an isolation characteristic.

摘要： Provided is a high-isolation switching device for a millimeter-wave band control circuit. By optimizing a cell structure to improve the isolation of an off-state without deteriorating the insertion loss of an on-state, it is possible to implement a high-isolation switching device useful in the design and manufacture of a millimeter-wave band control circuit such as a phase shifter or digital attenuator using switching characteristics. In addition, when a switch microwave monolithic integrated circuit (MMIC) is designed to use the switching device, it is not necessary to use a multi-stage shunt field effect transistor (FET) to improve isolation, nor to dispose an additional λ/4 transformer transmission line, inductor or capacitor near the switching device. Thus, chip size can be reduced, degree of integration can be enhanced, and manufacturing yield can be increased. Consequently, it is possible to reduce manufacturing cost.

摘要： A field effect transistor having a T- or Γ-shaped fine gate electrode of which a head portion is wider than a foot portion, and a method for manufacturing the field effect transistor, are provided. A void is formed between the head portion of the gate electrode and a semiconductor substrate using an insulating layer having a multi-layer structure with different etch rates. Since parasitic capacitance between the gate electrode and the semiconductor substrate is reduced by the void, the head portion of the gate electrode can be made large so that gate resistance can be reduced. In addition, since the height of the gate electrode can be adjusted by adjusting the thickness of the insulating layer, device performance as well as process uniformity and repeatability can be improved.
