silicon carbide - an overview | ScienceDirect Topics

Silicon carbide is the hardest of the conventional abrasives but has lower impact resistance than aluminium oxide and shows a higher wear rate when used for grinding steels. Silicon carbide wears more rapidly when used to grind metals that have an affinity for carbon such as iron and nickel. It is therefore used primarily for non-ferrous materials.

Deposition of Silicon Oxide, Silicon Nitride and Silicon

Silicon Carbide The utility of silicon oxide coatings is limited by its applicability for good barrier properties. There appears to be a fundamental limit to how effective SiO 2 thin films can be to water vapor transport9. Silicon carbide, in this case, has superior performance as a barrier to water vapor as compared to SiO 2. For example,

Micromechanical properties of silicon-carbide thin films

1,3-Disilabutane is used as a single-source precursor to deposit conformal silicon-carbide films on silicon atomic-force-microscopy cantilevers. By measuring the resonance frequency of the cantilever as a function of silicon-carbide film thickness and developing an appropriate model, the value of the film’s elastic modulus is determined.

Chemical Vapor Deposition (CVD) | Wafer processing | SVM

Chemical Vapor Deposition. Chemical vapor deposition (CVD) oxide is a linear growth process where a precursor gas deposits a thin film onto a wafer in a reactor. The growth process is low temperature and has a much higher growth rate when compared to thermal oxide. It also produces much thinner silicon dioxide layers because the film is
