The etch rate, chemical reactions and etched surface of $\beta$-silicon carbide are studied in detail using chlorine trifluoride gas. The etch rate is greater than 10 μm min-1 at 723 K with a flow rate of 0.1 $\ell$ min-1 at atmospheric pressure in a horizontal reactor.
Here we report an effective and non-expensive fabriion method of silicon carbide nanocrystals, with diameter below 10 nm, based on electroless wet chemical etching. Our samples show strong violet-blue emission in the 410-450 nm region depending on the used solvents and particle size.
The present work shows that HF etching of oxidized silicon carbide (SiC) leads to a very different surface termination, whether the surface is carbon or silicon terminated. Specifically, the silicon carbide surfaces are hydrophilic with hydroxyl termination, resulting from the inability of HF to remove the last oxygen layer at the oxide/SiC interface.

Metal assisted photochemical etching (ME) of 4H Silicon Carbide (SiC) was utilized to generate locally defined porous areas on single crystalline substrates. Therefore, Platinum (Pt) was sputter deposited on 4H-SiC substrates and patterned with photolithography and lift off. Etching was performed by immersing the Pt coated samples into an etching solution containing sodium persulphate and

Mechanisms in reactive ion etching of silicon carbide thin films
Chemical etching of SiC was found to proceed in pure water with the assistance of a Pt alyst. A 4H-SiC (0001) wafer was placed and slid on a polishing pad in pure water, on which a thin Pt film was deposited to give a alytic nature.Etching of the wafer surface was observed to remove protrusions preferentially by interacting with the Pt film more frequently, thus flattening the surface.

Silicon Carbide is the hardest blast media available. Its toughness and sharp edges make it a preferred abrasive for use on engraving stone, etching glass or rock tuling. It is an excellent replacement for sand, does not contain any free silica, and is reclaimable and reusable many times.
In this paper is detailed a technique for the plasma etching of silicon carbide (SiC) utilizing aluminum nitride (AlN) as a masking material. The fabriion technique enables the use of non-metallic etch masks to etch SiC which can aid in preventing micromasking defects on the etch surface and degradation in the health of plasma etch tools. This is the first report of this fabriion process
In this paper, we report the reactive ion etching (RIE) of trenches in 6H-silicon carbide using SF6/O2. The plasma parameters: etchant composition, gas flow rate, chaer pressure, and radio frequency power were optimized to obtain a maximum etch rate of 360Å/min. The etch rate of SiC was found to exhibit a direct correlation with the dc self bias except when the O2 percentage was varied
Selective crystalline silicon carbide growth can be achieved on patterned silicon-silicon oxide samples. Patterned SiC films are produced by making use of the high reaction probability of C.sub.60 with silicon at surface temperatures greater than 900 K and the negligible reaction probability for C.sub.60 on silicon dioxide at surface temperatures less than 1250 K.
The invention comprises a method of etching silicon carbide targets.In one eodiment, a reactive ion plasma is formed from a gas which is easily dissociated into its elemental species in the plasma, for which all of the dissociated elemental species are volatile in the plasma, and for which at least one of the elemental species is reactive with silicon carbide.
