Abstract

The present invention is related to an integrated circuit having an SiC etch stop layer fabricated using a method for removal of silicon carbide layers and in particular amorphous SiC of a substrate comprising the steps of: converting at least partly said exposed part of said carbide-silicon layer into an oxide-silicon layer by exposing said carbide-silicon layer to an oxygen containing plasma; and removing said oxide-silicon layer from said substrate.
