General Description
The 0.25-m mmW pHEMT 2MI (2-metal-interconnect)
process utilizes T-gate depletion-mode transistors and is
optimized for high-power and low-noise applications
through 50 GHz. Passives include 2 thick-metal intercon-
nect layers, precision TaN resistors, GaAs resistors, MIM
capacitors and through-substrate vias. The via-under-cap
process aids in size compaction and offers excellent
grounds at higher frequencies. Air bridges produce minimal
interconnect capacitance. This process is suitable for com-
mercial, military and space applications.
