Semiconductor Wafer Carrier Alumina Disk and Ceramic Edge Ring High precision ceramic components improve yield management for semiconductor wafer processing. Innovacera ceramic components provide precise dimensional stability, ultra-flatness and smoothness, and vacuum holding of wafers during inspection and processing. Low-surface-contact configurations minimize risk of back-side particles negatively affecting wafer geometry for precision applications. The main features of high precision ceramic parts: 1. Wear and abrasion resistance: Alumina is a tough technical ceramic with very good wear resistance. 2. High precision dimensions with tightening tolerance, it easier to get a perfect fitting relationship. 3. Chemical inertness, resistant to most of the strong acids and alkalis. 4. High-temperature ability: withstand up to 1600°C in oxidizing and reducing atmospheres. 5. Great mechanical properties, hardness, compressive, and flexural strength are much higher in...
