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.

With a Planar ICP, etch profiles are typically anisotropic, and the very high Ion density makes this type of ICP source ideal for etching hard materials such as Quartz, and Silicon Carbide. The Planar ICP flat coil can cause issues with uniformity across the substrate, and various techniques have been used to reduce this effect such as moving the chuck height, and adding magnetics to shape the
etch rate - definition - English
The method further includes thermally treating the inorganic anti-reflective coating material layer formed thereon such that the thermally treated anti-reflective coating material layer then has an associated second etch rate less than the first etch rate when exposed to the etchant, e.g. the second etch rate is less than 16 Å/minute, the second etch rate is less than 20 % of the first etch
