5-3 Applications and Benefits of SiC Electronics
Two of the most beneficial advantages that SiC-based electronics offer are in the areas of high-temperature
and high-power device operation. The specific SiC device physics that enables high-temperature and
high-power capabilities will be examined first, by several examples of revolutionary [...]

5-6-4-1-2 Bipolar and Hybrid Power Rectifiers
For higher voltage applications, bipolar minority carrier charge injection (i.e., conductivity modulation) should enable SiC pn diodes to carry higher current densities than unipolar Schottky diodes whose drift regions conduct solely using dopant-atom majority carriers . Consistent with silicon [...]

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 [...]

5-6-4-1 SiC High-Power Rectifiers
The high-power diode rectifier is a critical building block of power conversion circuits. Recent reviews of experimental SiC rectifier results are given in References 3, 134, 172, 180, and 181. Most important SiC diode rectifier device design trade-offs roughly parallel well-known [...]

3-12. Silicon Droplets
Silicon droplets can appear as either small mounds or depressions in the wafer surface. Normally absent, but if present are largely concentrated at perimeter of wafer. If present, estimate the % of speci ed area affected.

5-4-3 Growth of Hexagonal Polytype SiC Wafers
In the late 1970s, Tairov and Tzvetkov established the basic principles of a modified seeded sublimation growth process for growth of 6H-SiC. This process, also referred to as the modified Lely process,was a breakthrough for SiC in that [...]
