    Abstract:
    The etch rates of GaInAs and AlInAs were characterized using a mixture of methane, hydrogen, and argon as a function of self-bias voltage. Effectively infinite etch selectivity between GaInAs and AlInAs was found for voltages below 200 V. This highly selective etch process was applied to the gate recess of a high electron mobility transistor device, and preliminary device measurements were made
