High performance InP mHEMTs on GaAs substrate with multiple interconnect layers
We report the development of high performance metamorphic InP high electron mobility transistors (mHEMTs) with InAs composite channel design and three interconnect metal layers suitable for advanced RF and mixed signal integrated circuits. An un-passivated 35nm Lg device showed RF figures-of-merit of 533 GHz fτ and 343 GHz fmax. After full circuit processing, encapsulated in BCB, a 35nm Lg, 2×20um Wg mHEMT showed 387GHz fτ, 580GHz fmax. Four-inch wafer mapping shows excellent device uniformity and yield. We also report a broadband (206–294GHz) 3-stage G-, H-band common-source amplifier having a nominal S21 mid-band gain of 11–16dB employing thin-film microstrip wiring.
