KOH Etching - BYU Cleanroom

KOH Etching of Silicon Dioxide and Silicon Nitride. KOH etching of silicon nitride was not observed in the study. However, the silicon nitride etch rate is under 1 nanometer per hour if it etches at all. If silicon nitride is being used as a mask for silicon etching, potential etching of the silicon nitride need not be taken into consideration.

Silicon Carbide-Derived Carbon Coated Graphitized

2019-7-12 · Unique silicon carbide-derived carbon (SiC-CDC) and graphitized mesocarbon microbead (GMC) composites ([email protected]) were prepared by solid reaction of GMC and silicon and following etching reaction with chlorine. The microstructure of SiC-CDC was characterized as mainly amorphous carbon coined with some short and curved sheets of graphite.
