Introduction
Graphite plays a critical role in semiconductor manufacturing, where high-temperature stability, chemical resistance, and electrical conductivity are essential.
Precision graphite components are widely used in wafer handling, chemical vapor deposition, and vacuum chamber applications.
This article highlights the most common graphite parts in semiconductor equipment and explains why graphite is the material of choice.
1. Graphite Wafer Carriers
Graphite wafer carriers are used to hold silicon wafers during processing.
Why graphite?
- Excellent thermal stability
- Low contamination risk
- Good dimensional stability under high temperatures
Graphite wafer carriers are often customized for specific wafer sizes and process conditions.
2. Graphite Susceptors
Graphite susceptors are used in chemical vapor deposition (CVD) processes to support wafers while conducting heat uniformly.
Key benefits:
- High thermal conductivity
- Uniform heat distribution
- Resistance to chemical reactions
3. Graphite Fixtures and Clamps
Graphite fixtures and clamps secure parts inside vacuum chambers or high-temperature furnaces.
Advantages of graphite:
- Lightweight yet strong
- High-temperature resistance
- Non-reactive with semiconductor chemicals
Properly designed graphite fixtures improve process accuracy and yield.
4. Graphite Shields and Liners
Graphite shields and liners protect equipment surfaces from chemical attack or particle contamination.
Benefits:
- Easy to machine into complex shapes
- Chemically inert
- Can be replaced periodically to maintain equipment longevity
