The KLA Surfscan 2.1 Particle Defect System is a metrology tool for detecting particles and defects on wafers. The KLA Surfscan 2.1 supports 5-inch wafers.[1]
What it is
General reference — not yet source-verifiedA particle defect inspection system belongs to the wafer quality-control stage of semiconductor manufacturing. A machine in this class is used to find contamination-related defects before later process steps can propagate them into patterned product structures.
How it works
General reference — not yet source-verifiedA particle defect inspection system scans wafer surfaces with optical sensing and analyzes the returned signal for features that differ from the surrounding surface. A system in this class is designed to register small surface anomalies and map their locations for review and process control.
Applications
General reference — not yet source-verifiedA particle defect system is used in semiconductor fabrication for surface cleanliness monitoring and defect inspection. The class is relevant wherever wafers must be checked for particulate contamination that can affect yield and device reliability.
