3-8. 3C Inclusions Regions where step- ow was interrupted during epi layer growth. Typical regions are generally triangular although more rounded shapes are sometimes seen. Count once per occurrence. Two inclusions within 200 microns count as one.
5-4-1 Historical Lack of SiC Wafers Reproducible wafers of reasonable consistency, size, quality, and availability are a prerequisite for commercial mass production of semiconductor electronics. Many semiconductor materials can be melted and reproducibly recrystallized into large single crystals with the aid of a seed crystal, such as [...]
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. [...]
2-2.Wafer Thickness, Center Point Thin (thickness depends on wafer diameter, but is typically less than 1mm),circular slice of single-crystal semiconductor material cut from the ingot of single crystal semiconductor; used in manufacturing of semiconductor devices and integrated circuits; wafer diameters may range from 5mm to [...]
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.
3-9. Comet Tails Comet tails have a discrete head and trailing tail. These features are aligned parallel to the major at. Usually, all comet tails tend to be of the same length. Count once per occurrence. Two comet tails within 200 microns count as [...]
