SiC Ceramic Optical Path Board Introduction

SiC Ceramic Optical Path Board for Wafer Inspection Equipment Parallelism ≤0.02mm

SiC Ceramic Optical Path Board for Wafer Inspection Equipment Parallelism ≤0.02mm 0

A Silicon Carbide (SiC) Optical Path Board is a high-precision optical substrate manufactured from ultra-high-purity silicon carbide ceramic, specifically designed for dual optical path systems in wafer inspection equipment. It leverages the core material properties of silicon carbide—exceptional hardness, ultra-low coefficient of thermal expansion, high thermal conductivity, and high refractive index—to provide a stable, thermally stable reference platform for optical sensors and imaging systems. Through precision grinding and polishing processes, it achieves nanoscale flatness and surface roughness. Its excellent chemical inertness and high stiffness ensure long-term performance in harsh semiconductor manufacturing environments, significantly enhancing inspection accuracy and equipment reliability.
