Investigation on wet etching 4H-SiC damaged by ion implantation

In this work investigation on wet etching of ion implanted 4H-SiC has been performed. Starting with the search for a suitable etching solution is followed by investigations on how to damage 4H-SiC in an efficient way involving different implantation species in various doses. With the help of Monte Carlo simulations a model for the experimental findings is proposed to derive the limitations for the wet etch capability.
