The silicon carbide (SiC) cantilever paddle is a critical component made from reaction-bonded silicon carbide (RB-SiC). Designed with a cantilever structure, it offers outstanding high-temperature stability, corrosion resistance, and load-bearing capacity, making it an ideal choice for semiconductor diffusion furnaces, LPCVD systems, photovoltaic applications, and corrosive chemical environments.
High-Temperature Stability – No deformation under high temperatures (up to 1380 °C), ensuring reliable wafer handling.
Strong Load Capacity – Stable cross-section allows safe support of large-diameter wafers, compatible with existing furnace tubes for larger wafer sizes.
LPCVD Compatibility – Very low thermal expansion coefficient, closely matching LPCVD coatings, extending maintenance and cleaning cycles while reducing contamination.
Durability – Excellent resistance to extreme hot/cold thermal shock, significantly extending service life.
High Purity – Free of metallic contamination, meeting the stringent purity requirements of semiconductor and photovoltaic industries.
