Abstract :
A planar process of using proton isolation for modulationdoped GaAs/GaAlAs integrated circuits is presented. Devices with very low contact resistance (~ 5 × 10¿7 ¿ cm2) and very high transconductance (~ 210 ms/mm) have been achieved. DCFL ring oscillators with 10 ¿m switching FETs have been operated at ¿ = 36.6 ps at room temperature and 27.3 ps at 77 K. The lowest speed-power product is 2.43 fJ per gate.
