The KLA Candela 8620 Wafer is a wafer inspection system. The KLA Candela 8620 Wafer operates on single-phase power at 50/60 Hz. The KLA Candela 8620 Wafer accommodates 8-inch wafers.[1][2][3]
What it is
The KLA Candela 8620 is a wafer inspection system classified under semiconductor metrology and inspection equipment. The system is configured for single-phase operation at either 50 or 60 Hz. The Candela 8620 accommodates 8-inch wafers.[1][2][3]
How it works
General reference — not yet source-verifiedCandela-style wafer inspection systems operate by raster-scanning a laser spot across the wafer surface. Multiple detectors collect light at different angles: a normal-incidence detector captures reflected intensity, while oblique detectors capture scattered light. The system compares the measured signals against a reference to flag deviations that indicate defects. Advanced signal processing distinguishes defect types based on the signature of each channel's response.
