Purity,SEM Structure,thickness analysis of SiC coating
The purity of SiC coatings on graphite by using CVD is as high as 99.9995%. Its structure is fcc. The SiC films coated on graphite is (111) oriented as shown in the XRD data (Fig.1) indicating its high crystalline quality. The thickness of the SiC film is very uniform as shown in Fig. 2.
SINGLE CRYSTAL SILICON EPITAXIAL BASE
Product performance and application prospects.
Silicon carbide (SiC) coated base is the best base for single crystal silicon and GaN epitaxy, which is the core component of the epitaxy furnace. The base is a key production accessory for monocrystalline silicon for large integrated circuits. It has high purity, high temperature resistance, corrosion resistance, good air tightness and other excellent material characteristics.
