Graphite susceptors and components for silicon and SiC epitaxy
Special advantages of our SiC-coated graphite susceptors include extremely high purity, homogenous coating and an excellent service life. They also have high chemical resistance and thermal stability properties. We maintain very close tolerances when applying the SiC coating, using high-precision machining to ensure a uniform susceptor profile.
Refining SiC epi-growth for high-volume production - News
A high purity is critical, as it holds the key to a high growth rate. For silane chemistry, growth is typically between 5 μm/h and 15 μm/h. Many groups have shown that increasing the growth rate, in tandem with the use of substrates off-cut by 4°, enables a trimming of defect density and improvement in thickness and doping uniformity.
