1-2.Stacking Sequence
If we are going to make a laminated structure, we must know the thickness of each ply and the angle of each ply traditionally in degrees defined from the top layer down.

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 [...]
5-5-5 SiC Insulators: Thermal Oxides and MOS Technology The vast majority of semiconductor-integrated circuit chips in use today rely on silicon metal-oxide– semiconductor field-effect transistors (MOSFETs), whose electronic advantages and operational device physics are summarized in Katsumata’s chapter and elsewhere . Given the extreme usefulness and success of [...]
2-9.(Area) Wafer Contamination Any foreign matter on the surface in localized areas which is revealed under high intensity (or diffuse) illumination as discolored, mottled, or cloudy appearance resulting from smudges, stains or water spots.
5-3-1 High-Temperature Device Operation The wide bandgap energy and low intrinsic carrier concentration of SiC allow SiC to maintain semiconductor behavior at much higher temperatures than silicon, which in turn permits SiC semiconductor device functionality at much higher temperatures than silicon . As discussed in basic semiconductor electronic [...]
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 [...]
5-5 SiC Device Fundamentals To minimize the development and production costs of SiC electronics, it is important that SiC device fabrication takes advantage of existing silicon and GaAs wafer processing infrastructure as much as possible. As will be discussed in this section, most of the [...]
