| Abstract(in English) | We studied the RF characteristics of SiC-MESFETs with gate lengths from 0.3 to 1.5 μm that were fabricated on the same epitaxial wafer. When the gate length was less than 1.0 μm, the cutoff frequency ft and maximum oscillation frequency fmax were less dependent on the gate length. The degradation of these RF characteristics was apparently caused by the short-channel effect. To uncover the mechanism underlying this, we investigated static electrical characteristics, such as the transconductance and pinch-off voltage, of short-channel SiC-MESFETs and found that the short-channel effect occurred when the aspect ratio of the gate length to channel thickness was 5 or less. |
