Abstract :
In this paper, we report the incorporation of Source/Drain regrowth by MOCVD in InAlAs/InGaAs HEMT on InP substrate. Greatly improved RF performance of the device was observed, compared with standard HEMTs with the same layered structure. 1-μm gate-length device exhibits a 34% improvement of cutoff frequency fT and a 74% improvement of maximum oscillation frequency fmax.
