1-4.Density
The mass density or density of a material is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho). Mathematically, density is defined as mass divided by volume:

5-1 Introduction Silicon carbide (SiC)-based semiconductor electronic devices and circuits are presently being developed for use in high-temperature, high-power, and high-radiation conditions under which conventional semiconductors cannot adequately perform. Silicon carbide’s ability to function under such extreme conditions is expected to enable significant improvements to a far-ranging variety [...]
2-32.Semi-insulating Semi-insulating Doping with the impurities vanadium creates semi-insulating material of silicon carbide.
3-9. Comet Tails Comet tails have a discrete head and trailing tail. These features are aligned parallel to the major at. Usually, all comet tails tend to be of the same length. Count once per occurrence. Two comet tails within 200 microns count as [...]
2-14.Masking Defects also referred to as “Mound” When one defect prevents the detection of another defect, the undetected defect is called the masked defect. A distinct raised area above the wafer frontside surface as viewed with diffuse illumination.
5-6 SiC Electronic Devices and Circuits This section briefly summarizes a variety of SiC electronic device designs broken down by major application areas. SiC process and material technology issues limiting the capabilities of various SiC device topologies are highlighted as key issues to be addressed [...]
3-6. Edge Chips Areas where material has been unintentionally removed from the wafer.Do not confuse fractures in epi crown with edge chips.
