FAQ
Question: I am looking for single crystals of SiC 3C 2H 4H 6H and 15R polytypes with the crystallographic direction along 0001, thickness around 330 micrometer and wafer diameter between 2 cm -6 cm, Could you please send me the information about the dimensions and if you have other polytypes of SiC also include them in the quote?
Answer:4H and 6H SiC is commercialized, which we can offer you understand C(0001) accordingly, for 2H or 15R SiC, we can not offer, as it is not commercial value.
SiC 4H and SiC 6H manufacturer reference:PAM-XIAMEN is the world’s leading developer of solid-state lighting technology,he offer a full line: Sinlge crystal SiC wafer and epitaxial wafer and SiC wafer reclaim
Wafer Diameter
The linear distance across the surface of a circular slice which contains the slice center and excludes any flats or other peripheral fiduciary areas. Standard silicon wafer diameters are: 25.4mm (1"), 50.4mm (2"), 76.2mm (3"), 100mm (4"), 125mm(5"), 150mm (6"), 200mm (8"), and 300mm (12").
The linear dimension across the surface of a wafer. Measurement is performed manually with ANSI certied digital calipers on each individual wafer.
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 300mm.
Measured with ANSI certied non-contact tools at the center of each individual wafer.
