A novel method for etching trenches in silicon carbide | …
In this paper, a novel trench etching technique for silicon carbide is described. In this technique, ion implantation is used to first create an amorphous silicon carbide region. The amorphous layer is then etched away by wet chemical etching. Trenches of 0.3 to 0.8 μ have been obtained using a single implantaion/etching step. It has been demonstrated that deeper trenches can be obtained by

This abrasive is the favorite for glass etching and heavy automotive parts cleaning due to its high quality and ability to be recycled over and over again.
Silicon Nitride Atomic Layer Deposition: A Brief Review of …
Knoops et al. deposited high quality SiN x with BTBAS and N 2 plasma. 14 Film density was very high at 2.8 g/cm 3, and film wet etch rate was 0.2 nm/ min for growth at 400 C. Carbon contamination was less than 2%, but that increased to approximately 10% for films grown at 200 °C.
Silicon Carbide is extremely fast cutting and can be used to clean and etch very hard surfaces that would otherwise not be possible with other softer abrasives. Products manufactured from Tungsten Carbide may also be cleaned with Silicon Carbide.
