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:

2-15.Orange Peel Visually detectable surface roughening when viewed under diffuse illumination.
3-6. Edge Chips Areas where material has been unintentionally removed from the wafer.Do not confuse fractures in epi crown with edge chips.
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 [...]
2-31.N type A semiconductor has electrical conductivity between that of a conductor and an insulator. Semiconductors differ from metals in their characteristic property of decreasing electrical resistivity with increasing temperature.Semiconductors can also display properties of passing current more easily in one direction than the other, [...]
Most SiC electronic devices are not fabricated directly in sublimation-grown wafers, but are instead fabricated in much higher quality epitaxial SiC layers that are grown on top of the initial sublimation grown wafer. Well-grown SiC epilayers have superior electrical properties and are more controllable [...]
