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 … WebFeb 10, 2011 · SC-1 will etch the following materials: SiO 2, Si 3 N 4, Si, Ti and TiN. On top of this, SC-1 will grow an oxide on several materials (i.e., bare silicon).In this paper, a quantitative model for the SC-1 solution is presented. The etching of Ti and TiN is shown to be fundamentally different from the etching of SiO 2.
