Visually detectable surface roughening when viewed under diffuse illumination.
2-2.Wafer Thickness, Center Point Thin (thickness depends on wafer diameter, but is typically less than 1mm),circular slice of single-crystal semiconductor material cut from the ingot of single crystal semiconductor; used in manufacturing of semiconductor devices and integrated circuits; wafer diameters may range from 5mm to [...]
5-6-2 SiC RF Devices The main use of SiC RF devices appears to lie in high-frequency solid-state high-power amplification at frequencies from around 600 MHz (UHF-band) to perhaps as high as a few gigahertz (X-band). As discussed in far greater detail in References 5, 6, [...]
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 [...]
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 [...]
2-37.Test Grade Test Grade: A silicon carbide wafer of lower quality than Prime, and used primarily for testing processes. SEMI indicates the bulk, surface, and physical properties required to label silicon carbide wafers as “Test Wafers”.
2-16.Pits Individual distinguishable surface anomalies, which appears as a depression in the wafer surface with a lengthto-width ratio less than 5 to 1, and visible under high intensity illumination.
