High-Precision Alumina Ceramic Components for Advanced Semiconductor Manufacturing

1. Alumina Ceramic Wafer Chuck (Warpage < 0.05 mm) Engineered for ultra-flatness and thermal stability, our high-purity alumina (Al₂O₃) ceramic wafer chuck delivers exceptional planarity with warpage controlled to less than 0.05 mm—even under high-temperature processing conditions. Its excellent electrical insulation, chemical inertness, and low particle generation make it ideal for photolithography, etching, and CVD/PECVD applications. The precise surface finish ensures uniform clamping force and minimizes wafer stress, enhancing yield in sub-10nm semiconductor fabrication. 2. Mechanical Ceramic Arm Our mechanical ceramic arm is constructed from high-strength, fine-grained alumina ceramic, offering superior rigidity, dimensional stability, and resistance to wear and corrosion. Designed for integration into robotic transfer systems within vacuum or cleanroom environments, it maintains structural integrity during repetitive high-speed motion while eliminating metallic contamination. Ideal for precision alignment and positioning in wafer inspection and metrology tools. 3. Handling Ceramic Arm Optimized for delicate wafer transport, the handling ceramic arm combines lightweight design with high stiffness to enable smooth, vibration-free movement. Featuring ultra-clean surfaces and non-magnetic properties, it prevents particle shedding and electrostatic interference during wafer loading/unloading. Compatible with 200mm and 300mm wafer formats, this arm ensures reliable, contamination-free handling in front-end-of-line (FEOL) and back-end-of-line (BEOL) processes. Together, these alumina ceramic components provide a contamination-free, thermally stable, and highly reliable solution for next-generation semiconductor equipment—supporting higher yields, longer service life, and compliance with stringent cleanroom standards.
