Description
Silicon carbide ceramics have excellent mechanical properties at room temperature, such as high strength, high hardness, high elastic modulus,etc., it also has excellent high-temperature stability like high thermal conductivity, low thermal expansion coefficient, and good specific stiffness and optical processing performance.
They are especially suitable for producing precision ceramic parts for integrated circuit equipments such as lithography machines, mainly used to manufacture the SiC carrier/susceptor, SiC wafer boat, sucking disc, water cooling plate, precision measuring reflector, grating and other ceramic structural parts
Advantages
High temperature resistance: normal use at 1800 ℃
High thermal conductivity: equivalent to graphite material
High hardness: hardness second only to diamond, boron nitride
Corrosion resistance: strong acid and alkali have no corrosion to it, the corrosion resistance is better than tungsten carbide and alumina
Light weight: low density, close to aluminum
No deformation: low coefficient of thermal expansion
Thermal shock resistance: it can withstand sharp temperature changes, resist thermal shock, and has stable performance
Silicon carbide carrier such as sic etching carrier, ICP etching susceptor, are widely used in semiconductor CVD, vacuum sputtering etc. We can provide customers with customized wafer carriers of silicon and silicon carbide materials to meet different applications.
