Dear all, We have access to a STS DRIE etcher and would like to create mirror-like finish on the sidewalls with a depth of a few microns. What would be the sidewall smoothness limit with the STS etcher in terms of nano meters based on your experiences? What are the tricks/recipes to create such a smooth sidewall? If the sidewall is not smooth enough after the DRIE etching, what is the best treatment one has to further improve the sidewall roughness? Could you share the treatment recipe or point me to some good references? Thanks a lot!
