  • Abstract
    The authors have fabricated InGaAs MESFETs with a double selective gate recess process using a thin AlAs layer. Very low gate leakage is obtained since the gates are not in contact with the mesa sidewall. 1 μm×100 μm InGaAs MESFETs exhibit a transconductance, fT and fmax of 215 mS/mm, 24 GHz, and 70 GHz, respectively
