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 [...]

5-5-6 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 [...]

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 [...]

5-6-4-2 SiC High-Power Switching Transistors
Three terminal power switches that use small drive signals to control large voltages and currents (i.e., power transistors) are also critical building blocks of high-power conversion circuits. However, as of this writing, SiC high-power switching transistors are not yet commercially [...]

Total Thickness Variation (TTV): The maximum variation in the wafer thickness. Total Thickness Variation is generally determined by measuring the wafer in 5 locations of a cross pattern (not too close to the wafer edge) and calculating the maximum measured difference in thickness. The [...]

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 [...]
