2-32.Semi-insulating
Semi-insulating Doping with the impurities vanadium creates semi-insulating material of silicon carbide.

Semi-insulating Doping with the impurities vanadium creates semi-insulating material of silicon carbide.
2-21.Usable Area A cumulative subtraction of all noted defect areas from the frontside wafer quality area within the edge exclusion zone. The remaining percent value indicates the proportion of the frontside surface to be free of all noted defects (does not include edge exclusion).
5-4-1 Historical Lack of SiC Wafers Reproducible wafers of reasonable consistency, size, quality, and availability are a prerequisite for commercial mass production of semiconductor electronics. Many semiconductor materials can be melted and reproducibly recrystallized into large single crystals with the aid of a seed crystal, such as [...]
2-29.Resistivity The resistance to current flow and movement of electron and hole carries in the silicon carbide. Resistivity is related to the ratio of voltage across the silicon to the current flowing through the silicon carbide per unit volume of silicon carbide. The units for [...]
1-3.Mohs Hardness Rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised(1812)by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance [...]
5-4-4-2 SiC Epitaxial Growth Polytype Control Homoepitaxial growth, whereby the polytype of the SiC epilayer matches the polytype of the SiC substrate, is accomplished by “step-controlled” epitaxy . Step-controlled epitaxy is based upon growing epilayers on an SiC wafer polished at an angle (called the [...]
In solid state physics, a band gap, also called an energy gap or bandgap, is an energy range in a solid where no electron states can exist. In graphs of the electronic band structure of solids, the band gap generally refers to the energy [...]
