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.
2-31.N 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, [...]
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 [...]
1-7.Band-gap In solid state physics, a band gap, also called an energy gap or bandgap, is an energy range in a solid where no electron states can exist. In graphs of the electronic band structure of solids, the band gap generally refers to the energy [...]
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.
2-28.WARP Warp is the difference between the maximum and the minimum distances of the median surface of a free, un-clamped wafer from the reference plane defined above. This definition follows ASTM F657, and ASTM F1390,which deviation from a plane of a slice or wafer centerline [...]
5-6-4 SiC High-Power Switching Devices The inherent material properties and basic physics behind the large theoretical benefits of SiC over silicon for power switching devices were discussed Section 5.3.2. Similarly, it was discussed in Section 5.4.5 that crystallographic defects found in SiC wafers and epilayers [...]
