Aluminum nitride as a masking material for the plasma …

In this paper is detailed a technique for the plasma etching of silicon carbide (SiC) utilizing aluminum nitride (AlN) as a masking material. The fabriion technique enables the use of non-metallic etch masks to etch SiC which can aid in preventing micromasking defects on the etch surface and degradation in the health of plasma etch tools. This is the first report of this fabriion process
