Main features:

1. Silicon carbide ceramic tray
- High hardness and wear resistance: the hardness is close to diamond, and can withstand mechanical wear in wafer processing for a long time.
- High thermal conductivity and low thermal expansion coefficient: fast heat dissipation and dimensional stability, avoiding deformation caused by thermal stress.
- High flatness and surface finish: The surface flatness is up to the micron level, ensuring full contact between the wafer and the disk, reducing contamination and damage.
Chemical stability: Strong corrosion resistance, suitable for wet cleaning and etching processes in semiconductor manufacturing.
2. Silicon carbide ceramic tube
- High temperature resistance: It can work in high temperature environment above 1600°C for a long time, suitable for semiconductor high temperature process.
Excellent corrosion resistance: resistant to acids, alkalis and a variety of chemical solvents, suitable for harsh process environments.
- High hardness and wear resistance: resist particle erosion and mechanical wear, extend service life.
- High thermal conductivity and low coefficient of thermal expansion: fast conduction of heat and dimensional stability, reducing deformation or cracking caused by thermal stress.
