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.

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. WebHome University of Colorado Boulder
