2-25.FWHM
Full width at half maximum (FWHM) is an expression of the extent of a function, given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value.

3-1. Large Point Defects Defects which exhibit a clear shape to the unassisted eye and are > 50 microns across. These features include spikes, adherent particles, chips and craters. Large point defects less than 3 mm apart count as one defect.
1-8.Electrical Breakdown The term electrical breakdown or electric breakdown has several similar but distinctly different meanings. For example, the term can apply to the failure of an electric circuit. Alternatively, it may refer to a rapid reduction in the resistance of an electrical insulator that [...]
5-6-2 SiC RF Devices The main use of SiC RF devices appears to lie in high-frequency solid-state high-power amplification at frequencies from around 600 MHz (UHF-band) to perhaps as high as a few gigahertz (X-band). As discussed in far greater detail in References 5, 6, [...]
3-4. Step Bunching Step bunching is visible as a pattern of parallel lines running perpendicular to the major at. If present, estimate the % of speci ed area affected.
5-5-2 SiC-Selective Doping: Ion Implantation The fact that diffusion coefficients of most SiC dopants are negligibly small (at 1800°C) is excellent for maintaining device junction stability, because dopants do not undesirably diffuse as the device is operated long term at high temperatures. Unfortunately, this characteristic also largely [...]
3-7. ID Correct and Major Wafer Flat Both should be readily discernible.
