Abstract

A 50nm T-gate lattice-matched InP HEMT technology is presented with which devices with figures of 1600mS/mm for DC transconductance and 430GHz for cutoff frequency fT have been realised. This performance can be attributed to the use of a non-annealed/non-alloyed ohmic contact process which acts to reduce parasitic access resistances to the device. To the best of our knowledge, hese performance figures are the highest reported to date for a HEMT device fabricated from a lattice-matched InP material system.
