4.Silicon Carbide(SiC) Definition - XIAMEN POWERWAY

Silicon carbide (SiC), is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.

Silicon nitride - Wikipedia

Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3 N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert, being attacked by dilute HF and hot H

Lithography and Etching‐Free Microfabriion of Silicon

Silicon carbide (SiC)-based microsystems are promising alternatives for silicon-based counterparts in a wide range of appliions aiming at conditions of high temperature, high corrosion, and extreme vibration/shock. However, its high resistance to chemical substances makes the fabriion of SiC particularly chall-enging and less cost-effective.

4H Silicon Carbide Etching Using Chlorine Trifluoride Gas

The etching technology for 4H-silicon carbide (SiC) was studied using ClF3 gas at 673-973K, 100 % and atmospheric pressure in a horizontal reactor. The etch rate, greater than 10 um/min, can be obtained for both the C-face and Si-face at substrate temperatures higher than 723 K. The etch rate increases with the increasing ClF3 gas flow rate.
