Abstract :
In this paper, we fabricated a 0.13 μm ASR gate In0.65GaAs P-HEMT by inserting additional dummy gate line and using DDS gate structure. The fabricated device showed excellent DC and RF characteristics with a improvement in output conductance (Gds) and maximum oscillation frequency (fmax). These results demonstrate that an ASR gate structure for high performance 100 nm scale InP P-HEMT.
