P. Fay et al., Fabrication of monolithically-integrated InAlAs/InGaAs/InP HEMTs and InAs/AlSb/GaSb resonant interband tunneling diodes, IEEE DEVICE, 48(6), 2001, pp. 1282-1284
The integration of InAs/AlSb/GaSb resonant interband tunneling diodes (RITD
s) with InAlAs/InGaAs/InP high electron mobility transistors (HEMTs) is rep
orted. The integrated devices exhibit nearly identical performance to discr
ete control devices from de through microwave frequencies. RITDs with peak
current densities of 24.5 kA/cm(2) and peak voltages of 0.12 V have been de
monstrated for devices with 1.2-nm thick AlSb barriers. HEMTs with 0.2-mum
gates have been fabricated, and f(t)s of 127 GHz and f(max)s of 183 GHz hav
e been obtained. To the authors' knowledge, this is the first report of the
monolithic integration of RITDs with HEMTs on InP.
