General Description
The 0.25-m mmW pHEMT 3MI (3-Metal-Interconnect)
process combines high power density and gain per stage
performance. The process is optimized for high-power and
low-noise operation through 50 GHz. Passives include 3
thick-metal interconnect layers, precision TaN resistors,
GaAs resistors, through-substrate vias and 3 MIM capaci-
tance densities. The via-under-cap process aids in size
compaction and offers excellent grounds at higher frequen-
cies. Air bridges produce minimal interconnect capacitance
and the protective overcoat layer provides environmental
robustness.
