5-3-3 System Benefits of High-Power High-Temperature SiC Devices
Uncooled operation of high-temperature and high-power SiC electronics would enable revolutionary
improvements to aerospace systems. Replacement of hydraulic controls and auxiliary power units with
distributed “smart” electromechanical controls capable of harsh ambient operation will enable substantial
jet-aircraft weight savings, reduced [...]

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.

2-29.Resistivity
The resistance to current flow and movement of electron and hole carries in the silicon carbide. Resistivity is related to the ratio of voltage across the silicon to the current flowing through the silicon carbide per unit volume of silicon carbide. The units for [...]

5-4-1 Historical Lack of SiC Wafers
Reproducible wafers of reasonable consistency, size, quality, and availability are a prerequisite for
commercial mass production of semiconductor electronics. Many semiconductor materials can be melted
and reproducibly recrystallized into large single crystals with the aid of a seed crystal, such as [...]

5-2-1-2 Electrical Properties
Owing to the differing arrangement of Si and C atoms within the SiC crystal lattice, each SiC polytype
exhibits unique fundamental electrical and optical properties. Some of the more important semiconductor
electrical properties of the 3C, 4H, and 6H SiC polytypes are given in [...]
