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.

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 [...]
2-33.P type A semiconductor has electrical conductivity between that of a conductor and an insulator. Semiconductors differ from metals in their characteristic property of decreasing electrical resistivity with increasing temperature.Semiconductors can also display properties of passing current more easily in one direction than the other, [...]
3-7. ID Correct and Major Wafer Flat Both should be readily discernible.
5-2-2-1 SiC Crystallography: Important Polytypes and Definitions Silicon carbide occurs in many different crystal structures, called polytypes. A more comprehensive introduction to SiC crystallography and polytypism can be found in Reference 9. Despite the fact that all SiC polytypes chemically consist of 50% carbon atoms covalently bonded [...]
5-4-2 Growth of 3C-SiC on Large-Area (Silicon) Substrates Despite the absence of SiC substrates, the potential benefits of SiC hostile-environment electronics nevertheless drove modest research efforts aimed at obtaining SiC in a manufacturable wafer form.Toward this end, the heteroepitaxial growth of single-crystal SiC layers on [...]
