3-8. 3C Inclusions
Regions where step- ow was interrupted during epi layer growth. Typical regions are generally triangular although more rounded shapes are sometimes seen. Count once per occurrence. Two inclusions within 200 microns count as one.

5-7-1 Future Tied to Material Issues The previous sections of this chapter have already highlighted major known technical obstacles and immaturities that are largely responsible for hindered SiC device capability. In the most general terms, these obstacles boil down to a handful of key fundamental [...]
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 [...]
5-5-6 SiC Device Packaging and System Considerations Hostile-environment SiC semiconductor devices and ICs are of little advantage if they cannot be reliably packaged and connected to form a complete system capable of hostile-environment operation. With proper material selection, modifications of existing IC packaging technologies appear [...]
3-5. Backside Cleanliness Veri ed by inspecting for a uniform color to the wafer backside. Note there is a darker region near the center of some higher doped wafers. Backside cleanliness speci ed as percent area clean.
2-8.Secondary Flat Orientation A at of shorter length than the primary orientation at,whose position with respect to the primary orientation at identies the face of the wafer.
Most analog signal conditioning and digital logic circuits are considered “signal level” in that individual transistors in these circuits do not typically require any more than a few milliamperes of current and <20 V to function properly. Commercially available silicon-on-insulator circuits can perform complex digital and [...]
