This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
General reference — not yet source-verifiedThe KLA 2138 XP is a wafer defect inspection system used in semiconductor metrology and inspection.
How it works
General reference — not yet source-verifiedA wafer defect inspection system scans wafer surfaces and detects defects by measuring how features or particles affect the optical signal returned from the wafer. Instruments in this class are used to find particulate contamination, pattern anomalies, and other surface or surface-related defects before those defects propagate to later process steps.
Where it fits in the process flow
General reference — not yet source-verifiedThis class of equipment is placed in the inspection and metrology part of semiconductor manufacturing, where wafers are checked between process operations to verify surface condition and identify defects early. It typically supports yield control by screening wafers before further processing or release to subsequent fabrication steps.
Applications
General reference — not yet source-verifiedThe machine is used for wafer defect inspection in semiconductor manufacturing. In this class, common uses include finding particles, surface defects, and pattern-related anomalies on processed wafers.
