At 200 °C, the drain current I<sub>DS</sub> of a passivated diamond FET remained constant for at least more than 2 h. No degradation of FET characteristics was observed after the 200 °C heating cycle. Furthermore, a passivated diamond FET with a gate length of 0.2 μm showed high maximum I<sub>DS</sub> of -1000 mA/mm and an RF output power density of 2 W/mm.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>MOSFET; adsorption; alumina; diamond; heating; nitrogen compounds; passivation; thermal stability; Al<sub>2</sub>O<sub>3</sub>; FET characteristics; H-terminated diamond FET; NO<sub>2</sub>; RF output power density; adsorption; diamond FET passivation; drain current; gate length; heating cycle; hydrogen-terminated diamond field-effect transistors; passivated diamond FET; passivation; size 0.2 mum; temperature 200 degC; thermally stable operation; Aluminum oxide; Diamond-like carbon; FETs; Logic gates; Passivation; Temperature measurement; Thermal stability; <formula formulatype=$ $hbox{Al}_{2}hbox{O}_{3}$ passivation; $hbox{NO}_{2}$; diamond; field-effect transistor (FET); thermal stability;
