Gate Etch: Prior to the gate formation a recess is etched into the semiconductormaterial to remove the highly-doped contact material above the channel. Historically,this was an “etch-to-current” activity where the etch rate would be carefully calibratedand a timed etch would be used to target the desired recess depth.

The higher transport of this strained layer pushed frequency performance towards GHz by the late s, although GaAs ceded the performance advantage to InP-based HEMTs by then. In spite of higher frequency operation for InP-based devices, GaAs devices’ favourable combination of speed and breakdown characteristics led to the dominance of.
