2-3.Wafer Flat Length
Linear dimension of the at measured with ANSI certied digital calipers on a sample of one wafer per ingot.
2-24.Wafer Orientation Wafers are grown from crystal having a regular crystal structure, with silicon having a diamond cubic structure with a lattice spacing of 5.430710 Å (0.5430710 nm).When cut into wafers, the surface is aligned in one of several relative directions known as crystal orientations. [...]
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 [...]
3-2. Scratches Grooves or cuts below the surface plane of the wafer having a length-to-width ratio of greater than 5 to 1. Scratches are speci ed by the number of discrete scratches times the total length in fractional diameter.
5-3-2 High-Power Device Operation The high breakdown field and high thermal conductivity of SiC coupled with high operational junction temperatures theoretically permit extremely high-power densities and efficiencies to be realized in SiC devices. The high breakdown field of SiC relative to silicon enables the blocking voltage region [...]
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 [...]
SILICON CARBIDE (SiC) materials are currently metamorphosing from research and development into a market driven manufacturing product. SiC substrates are currently used as the base for a large fraction of the world production of green, blue, and ultraviolet light-emitting diodes (LEDs). Emerging markets for [...]
