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. Age/saturation of etchant bath: Etch rate can be affected by how long the etchant bath has been sitting, and/or how much material has been etched in the …
