Etching Defect Analyzer

Comprehensive defect analysis and root cause investigation tool. Track defect types (micromasking, grass, notching, trenching, polymer residue, sidewall roughness, CD variation), perform Pareto analysis, visualize wafer maps, identify trends, classify severity, and access corrective action database.
