Chromium nitride etching

WebAug 1, 2024 · Chromium oxide etches in ceric ammonium nitrate etchants. In contrast to Cr metal, which etches in a well-controlled fashion, we find that our chromium oxide films exhibit an incubation time before etching begins and appear to etch preferentially from their edges. The reason for this behavior is unknown. WebDry etching is widely used as the final surface treatment for GaN substrate because it is already commonly used for producing the mesa structures of nitride thin films in LED and LD devices [72–74]. Reactive ion etching, electron cyclotron resonance, and inductively coupled plasma (ICP) technology are all used in this approach.

WebApr 3, 2024 · Therefore, for consistent etch rate, temperature must be held constant. Some etchants (e.g. phosphoric acid for etching silicon nitride) must be heated to give a sufficiently high etch rate.
