Si Epitaxial Parts

What are Si epitaxial parts?

Si epitaxial parts are customized components installed in silicon epitaxy equipment and related semiconductor processing systems. Typical products include susceptors, wafer carriers, barrels, support trays, pedestals and other process fixtures.

These components are exposed to high temperatures, process gases and repeated thermal cycles. Their material properties, dimensional accuracy, surface condition and structural stability can affect wafer support, temperature distribution, process repeatability and equipment maintenance cycles.

Semicera provides customized Si epitaxial parts based on equipment drawings, samples and process requirements. Depending on the component structure and application environment, high-purity graphite can be used as the substrate, with CVD SiC coating applied to functional surfaces where required.

Note: For complex components, manufacturability, coating accessibility and inspection requirements should be evaluated before final production.

Production and Testing Process

The production route is determined according to the component structure and technical requirements. Typical stages may include:

Drawing or Sample Evaluation → Material Selection → Graphite Machining → Critical Dimension Inspection → CVD SiC Coating → Surface Inspection → Final Verification → Packaging

For customized or replacement projects, customers may provide drawings, existing samples or key process parameters. Relevant dimensions, material requirements and inspection items can then be confirmed before production.

Frequently Asked Questions (FAQ)

Q: Can Si epitaxial parts be manufactured according to customer drawings?
A: Yes. Semicera supports customized manufacturing based on technical drawings and agreed specifications. Complex component structures can be evaluated before production.

Q: Can you manufacture replacement parts from an existing sample?
A: Depending on the sample condition and measurable features, a component can be evaluated for measurement and reverse engineering. Final manufacturing requirements should be confirmed before production.

Q: Are all Si epitaxial parts coated with CVD SiC?
A: Not necessarily. The material and surface treatment should be selected according to the component function, process environment and equipment requirements.

Q: What information is needed for a quotation?
A: A drawing is preferred. If a drawing is unavailable, customers can provide key dimensions, photos, material requirements, operating temperature and process environment information for an initial evaluation.
