  • Abstract
    A methane/hydrogen plasma has been used for the gate recessing of E/D MESFETs. Source-drain resistance measurements after thermal annealing have been performed on gate-recessed FETs without gate metal to check for the recovery of the electrical degradation introduced by the plasma. It was found that the damage could be restored after annealing at 350 degrees C.
