Tungsten silicide resistors in the range 50¿300 ¿ sheet resistance have been deposited on GaAs by RF sputtering and patterned by etching in an SF6 plasma. High-temperature stability has been demonstrated and a change in resistance of less than 01% after lOOOh at 125°C achieved with passivated resistors.
