1-3.Mohs Hardness
Rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised(1812)by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.
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.
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, [...]
2-7.Primary Flat Orientation The at of the longest length on the wafer, oriented such that the chord is parallel with a specied low index crystal plane. Measured on one wafer per ingot using Laue back-reection technique with manual angle measurement.
2-27.BOW Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the median surface to the reference plane. Where the reference plane is defined by three corners of equilateral triangle. This definition is based on now obsolete [...]
2-22.Surface Roughness Often shortened to roughness, is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small the surface [...]
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 [...]
