FAQ
Q1. What is a SiC Tray used for?
      It is mainly used to support, carry, position and process wafers or other components in high-temperature semiconductor processes such as CVD, PECVD, diffusion, oxidation, annealing and RTP.

Q2. Can the SiC Tray be customized?
      Yes. Dimensions, thickness, shape, slot geometry, mounting holes and complex structures can be customized based on customer drawings and application requirements.

Q3. What material options are available?
      The published product range includes CVD SiC, SSiC and RBSiC. The appropriate material should be selected according to purity, operating temperature, process atmosphere, contamination requirements and cost targets.

Q4. What information is required for a quotation?
      Material + Size + Thickness + Structure + Slot/Hole Details + Surface Finish + Tolerance + Quantity + Application + Operating Temperature
      For non-standard products, a 2D drawing or 3D CAD file is highly recommended.

Q5. What is the maximum operating temperature?
      Your current public SiC Tray product page specifies an operating temperature of ≤1600°C. The actual usable temperature should be confirmed according to the material grade and process environment.

Q6. Can the surface be polished?
      Yes. Precision grinding or polishing can be provided according to the application requirements.

Q7. Can you provide OEM/ODM?
      Yes. OEM/ODM customization is supported based on customer drawings and application requirements.

Q8. Why choose SiC instead of quartz or graphite?
      SiC offers advantages in high-temperature stability, mechanical strength, thermal performance and chemical stability. However, material selection should always be based on the actual process rather than assuming that SiC is universally superior to quartz or graphite.
