Semixlab SiC Coated Wafer Susceptor core advantages

Excellent high temperature resistance

High temperature stability: SiC has a melting point of up to 2700℃ and can work stably for a long time in a process environment of 1000℃~1600℃ (such as CVD, MOCVD, epitaxial growth, etc.), which is much better than stainless steel or aluminum alloy carriers. Low thermal expansion coefficient, not easy to deform at high temperature, and maintain wafer positioning accuracy.

Thermal shock resistance: SiC has high thermal conductivity, can quickly and evenly dissipate heat, and reduce the risk of cracking caused by sudden temperature changes (more durable than graphite).

Excellent corrosion and pollution resistance

Resistant to corrosive gases such as HCl, H2, NH3(common in etching and epitaxial processes), preventing the carrier from being corroded and causing particle contamination. Strong anti-oxidation performance, more stable than graphite in high-temperature oxygen-containing environments (graphite requires coating protection, while SiC itself is resistant to oxidation). SiC coating can achieve a purity of more than 99.9999%(6N), preventing metal impurities (such as Fe, Ni) from contaminating the wafer, and is particularly suitable for silicon-based and wide bandgap semiconductor (GaN, SiC) manufacturing.

Excellent thermal conductivity and thermal uniformity

Fast heat conduction ensures uniform heating of the wafer (reduces uneven thickness during epitaxial growth). Suitable for rapid temperature rise and fall processes (such as RTP rapid annealing) to improve production efficiency. The thermal expansion coefficient of SiC is close to that of silicon (Si) and silicon carbide (SiC) wafers, reducing lattice defects caused by thermal stress.

Compatibility and design flexibility

SiC coatings can be deposited on substrates such as graphite, molybdenum, and carbon fiber, taking into account both lightness and high strength. Through CVD or spraying processes, complex structures of carriers (such as porous structures and embedded heating elements) can be prepared.
