SiC properties are recognized as being advantageous for fabriion of power devices. Although substrate costs and defect densities are decreasing, SiC is not yet as mature and consistent as silicon. However, significant progress is underway to more fully understand the cause-and-effect relationships between the variations and defects in SiC substrates and devices.

Silicon Carbide Formula: SiC. Silicon Carbide Description: 1) Produced in electric resistance furnaces with a mixture of coke, sand, sawdust, and a small amount of salt. It is blocky and sharp edged. Also from Sic crystals. 2) It is extremely hard, has a high thermal conductivity and low thermal expansion. Not attacked by most acids and
Six Sigma focuses on reducing process variation and enhancing process control, whereas lean drives out waste (non-value added processes and procedures) and promotes work standardization and flow. The distinction between Six Sigma and lean has blurred, with the term "lean Six Sigma" being used more and more often because process improvement

Silicon carbide is also called "emery powder" or "refractory sand." The usual manufacturing process of SiC is to coine silica sand, tar (or coke), woodchip (and salt when manufacturing green SiC) and other materials in an electric resistance furnace at a high temperature.
Silicon carbide is mostly used for its hardness and strength, though its coined ceramic and semiconductor properties make SiC excellent in the manufacturing of fast, high-voltage, and high-temperature devices . Properties of silicon carbide. Robust crystal structure. Silicon carbide is composed of light elements, silicon (Si) and carbon (C).
