COHO
Semiconductor Business
COHO’s Semiconductor Business is built around three core capabilities: advanced ceramic materials, thermal management, and precision manufacturing. By integrating material formulation, precision forming, sintering, precision machining, and quality validation, COHO develops critical components engineered for demanding semiconductor environments involving high temperatures, high vacuum, plasma exposure, and ultra-clean processing conditions.
Our advanced material portfolio includes aluminum nitride (AlN), aluminum oxide (Al₂O₃), silicon carbide (SiC), yttrium oxide (Y₂O₃), YAG, and aluminum silicon carbide (AlSiC). Key products and applications include AlN heaters, ceramic substrates, lift pins, nozzles, and precision ceramic components for semiconductor process chambers. COHO also continues to advance its technologies in high-thermal-conductivity and plasma-resistant materials to meet the evolving requirements of next-generation semiconductor equipment.
Driven by the rapid growth of AI, high-power semiconductors, and advanced semiconductor processes, COHO continues to enhance material purity, thermal performance, dimensional accuracy, and process stability.
By establishing a comprehensive technology platform spanning advanced materials, precision components, and application solutions, COHO is committed to becoming a trusted advanced materials partner for the global semiconductor equipment and advanced thermal management industries.
