Carbide-derived carbon - Wikipedia

Carbide-derived carbon (CDC), also known as tunable nanoporous carbon, is the common term for carbon materials derived from carbide precursors, such as binary (e.g. SiC, TiC), or ternary carbides, also known as MAX phases (e.g., Ti 2 AlC, Ti 3 SiC 2). CDCs

Deep reactive-ion silicon carbide etching | TechLink

The resulting etched hexagonal SiC material’s etch features have a width of fewer than 8 μm and an aspect ratio (trench depth: trench width) greater than 25. The method also includes etching of other SiC materials such as bulk substrate materials, SiC material layers bonded to a silicon oxide layer, suspended SiC material layers, or a SiC material layer anodically bonded to a glass layer.
