Used KLA CANDELA 8600 for Sale

Description

KLA-Tencor Candela 8600 Optical Surface Analyzer (OSA) is a laser-based inspection system for semiconductor and optoelectronic wafers. It is manual wafer handling tool. The Candela defect detection system simultaneously measures surface reflectivity and topography for automatic defect detection and classification. The defect detection system's inspection technology combines scatterometry, ellipsometry, reflectometry, and topographical analysis to non-destructively inspect wafer surfaces for defects, and film thickness uniformity, of opaque substrates, epi layers, and transparent film coatings (SiC, GaN, sapphire). *. Fully refurbished. Installed in Clean-room. Can demonstrate anytime.
