Plasma Etch Cyclic
Step 1
Process details
notes:High temperature up to 650 degrees Celsius achievable; substrate support uses resistive heating elements; process performed in plasma processing chamber with RF antenna assembly
steps:expose oxide layer on substrate to first plasma to break oxygen bonds, expose oxide layer to second plasma to convert oxide to evaporable layer at first temperature, evaporate evaporable layer at second temperature higher than first temperature to expose group III-V semiconductor surface, expose group III-V semiconductor surface to oxygen-containing gas to oxidize surface, repeat iteratively until recessed depth of predetermined depth is formed, form group III-V semiconductor channel in predetermined recessed depth
