In this study, we have presented a source-connected field plate (SCFP) InAs high electron mobility transistor (HEMT) and evaluated its potential for using in high-speed and low-power logic applications. The fabricated device demonstrated good electrical characteristics including low subthreshold swing (SS) of 76 mV/decade, drain induced barrier lowering (DIBL) of 44 mV/V, I-ON/I-OFF ratio of 2.4x10(4), an off-state gate leakage current of less than 5x10(-6) A/mm and a G(m,max) of 1100 mS/mm at V-DS = 0.5 V. When increasing the drain-source bias (V-DS) to 1.0 V, the G(m,max) increased to 1750 mS/mm with a cut-off frequency of 113 GHz. These results revealed that the fabrication of source-connected field plate InAs HEMTs achieved excellent device performance for high-speed and low-power logic applications.
