Products Description
Ceramic silicon carbide chucks are advanced functional components manufactured from high-purity silicon carbide ceramic materials.
They are specifically engineered for precise fixation, support, and thermal conduction within ultra-high vacuum and extreme process environments. As core consumables for semiconductor manufacturing equipment-such as lithography machines, etchers, and CVD/PVD systems-their performance directly determines chip manufacturing precision, yield rates, and production efficiency.
Product performance
- Exceptional Hardness and Wear Resistance: With a Mohs hardness exceeding 9.2, silicon carbide is one of the hardest technical ceramic materials, second only to diamond. This makes silicon carbide products like silicon carbide bushings, silicon carbide bearings, and silicon carbide mechanical seals highly resistant to wear and ideal for wear resistant ceramics applications.
- Superior Thermal and Chemical Stability: It exhibits an extremely low thermal expansion coefficient and can operate in temperatures up to 1650°C in inert atmospheres. This refractory property, combined with excellent resistance to thermal shock and corrosion from acids and alkalis, makes it perfect for silicon carbide heating elements, silicon carbide protection tubes, and components in CMP and ICP processes.
- Excellent Thermal Conductivity and Electrical Tunability: Its high thermal conductivity (often superior to copper at high temperatures) makes silicon carbide plates ideal as thermal management substrates. Its electrical resistivity can be precisely engineered, enabling its use in electrostatic chucks (ESCs) and as a wide bandgap semiconductor material for power electronics.
- High Strength and Lightweight: Sintered SiC offers high mechanical strength and stiffness at a relatively low density, contributing to the durability and precision of components like silicon carbide rollers and paddles.
- Manufacturing Versatility: Silicon carbide ceramics can be formed into complex shapes via sintering, reaction bonding, or Chemical Vapor Deposition (CVD). Post-processing like silicon carbide coating (e.g., CVD SiC coating) can further enhance surface properties for specific applications.
Product application
- Semiconductor Manufacturing: Essential for wafer handling and processing. Key products include ESCs for etching (ICP) and deposition (PVD, CVD), silicon carbide carriers for CMP, and process kits like silicon carbide boats, silicon carbide paddles, and silicon carbide furnace tubes. High-purity grades are critical to prevent contamination.
- Industrial & Metallurgical: Used as kiln furniture (rollers, beams), components in pumps and valves (seals, bushings), linings for cyclones, and crucibles for metal melting. Silicon carbide refractory materials are used in high-temperature furnaces.
- Energy & Environmental: Components in heat exchangers (silicon carbide heat exchanger tubes), seal rings for pumps in harsh environments, and substrates for sputtering targets.
- Aerospace & Defense: Used in ceramic matrix composites (CMCs), armor, and components for high-temperature, high-stress environments due to its ultra-high temperature capability.
- Electronics: As a substrate for GaN on SiC in RF devices and a base material for silicon carbide power semiconductors themselves.
- Automotive: Components in braking systems and water pumps, and as the core material for electric vehicle power electronics.
- Additive Manufacturing: Growing use in ceramic additive manufacturing for producing complex silicon carbide parts.
