Precision Ceramic Solutions for Semiconductor Manufacturing

Direct-factory precision diamond grinding and micro-machining of high-reliability technical ceramics for wafer processing, advanced lithography stages, and severe plasma etching environments.

Modern semiconductor fabrication exige materials capable of withstanding extreme localized heat densities, highly corrosive reactive ions, and aggressive plasma erosion. KoreCera provides world-class mid-to-backend precision grinding, micro-drilling, and micro-lapping (Ra 0.02) services for custom Alumina (Al₂O₃), Silicon Carbide (SiC), and Silicon Nitride (Si₃N₄) structural components. Our specialized multi-axis CNC grinding setups overcome technical ceramic brittleness to deliver high dimensional repeatability for critical sub-systems—ensuring exceptional plasma-chemical resistance and zero structural warp.
