Etching of silicon carbide for device fabriion and …
We have investigated the etching of SiC using inductively-coupled-plasma reactive ion etching with SF6-based and Cl2-based gas mixtures. Etch rates have been investigated as functions of bias voltage, ICP coil power, and chaer pressure. It will be shown, for the first time, that SiC surfaces etched in Cl2-based plasmas yield better surface electrical characteristics than those etched in SF6

Professional Glass Consultants: What is glass etching?
The dust from both silicon carbide and aluminum oxide are considered to be "nuisance dusts" rather than a hazardous material as sand is, so they are both safer than using sand. Since both materials cost less than 80 cents per hour to use, carbide is the professional''s choice for etching glass.
Characterization of masking layers for deep wet etching …
2005/8/1· Plasma was also used to etch glass, and this typically resulted in a low etch rate of 10 nm/min . Deep reactive ion etching (DRIE) using the ICP system can produce high aspect ratio glass microstructures  , but it is a very expensive process and the masking layer of 20 μm thick electroplated Ni is relatively difficult to achieve.
Wet Etching - an overview | ScienceDirect Topics
Silicon, silicon dioxide, aluminum, tungsten (and other refractory metals), and glass/quartz can be etched by either method. Diamond, silicon carbide, titanium carbide and gallium nitride are materials that do not have wet etch processes, but RIE processes do exist.
Acid Etching Glass
How To Etch Instructions What is Glass Etching? Glass etching with acid is a process by which a resist is applied to glass before it is dipped into hydrofluoric acid. Once in the acid, the coloured surface that it not covered with resist is etched away, lightening or changing its’ colour.

A Guide to Abrasive Blasting Media | Finishing Systems
Consequently, the process of ‘sandblasting’ is typically conducted utilizing alternative types of abrasive material: Glass Beads: Glass is not as aggressive a blasting media as other materials, such as steel shot or silicon carbide.
Silicon carbide - Wikipedia
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Plasma Etching - an overview | ScienceDirect Topics
The chemical nature of a process gas dictates how its plasma reacts with the surface of a material and therefore the effectiveness of plasma etching. For instance, tetrachloromethane (CCl 4) etches silicon and aluminium effectively but the plasma etching of silicon dioxide and silicon nitride requires the use of trifluoromethane (CHF 3).
