    Inductively coupled plasma dry etching has been proceeded to form high breakdown-voltage mesa-structured GaN p-n junction diodes for power electronics applications. Occurrences of crystalline damages were inevitable during the etching by accelerated reactive ions. However; the damages were removed by thermal treatment at 850°C, which lead low specific on-resistances (Ron<1mΩcm2) and high breakdown voltages (VB>4.2kV) of the diode.
