Abstract:
A double delta-doped channel 4H-SiC MESFET is proposed to kick out degradation of the DC and RF performances caused by the surface traps, by forming a quantum-well-like potential well and separating an effective channel from the surface. To obtain an optimum device structure, the DC and RF performances of double delta-doped channel MESFETs having various delta-doping concentrations but the same pinch-off voltage with that of conventional MESFET were also investigated. The SilvacoTM simulation results show that the double delta-doped channel MESFET achieved more improvement of the drain current

This work provides experimental result on fabricated 4H-SiC lateral power MESFET intended to be used in further development of high temperature integrated circuits for power application. The power SiC MESFET device was developed using a planar technology on silicon carbide and P implant isolation technique. Its destination to monolithic integration demands a lateral layout connection topology. The use of quite high doped N type epitaxial layer (1017cm-3) typical for the integrated circuits raises difficulties to keep the leakage current of the Schottky gate in a decent range.

The potential of SiC MESFETs has been demonstrated for high frequency applications on several circuits in the 1-5 GHz frequency range. Although MESFET structures are conventionally used for RF applications, in this paper we report a low voltage (180V) power switch and its current limiting application based on a double gate MESFET structure, showing enhanced forward and blocking capabilities. The reported devices utilize a thin highly doped p-type layer implanted at high energy as buffer layer.

We describe a new, unified model for MEtal Semiconductor Field Effect Transistors (MESFETs) which covers all ranges of operation, including the subthreshold regime. The current-voltage (I-V) and capacitance-voltage (C-V) characteristics are described by continuous, analytical expressions with relatively few, physically based parameters. The model includes effects such as velocity saturation, parasitic series resistances, the dependence of the threshold voltage on drain bias, finite output conductance in saturation, and temperature dependence of the device parameters.

In order to increase the output power and drain efficiency, MESFETs in SiC have been made with a double gate recess technique. Typical device characteristics of the MESFETs are drain currents of 380mA/mm, breakdown voltages of 80V and ft/fmax of 10/25 GHz respectively. These transistors exhibit power densities of 3W/mm@3GHz in class AB operation and drain efficiencies of 60%. Packaged devices with 3 mm gate periphery of this type, with via-hole grounding, gave power densities of 1.2 W/mm@6GHz at 50 V drain bias.
