Integrated PL, AOI, and Spectrum Analysis

  • PL Image
    • Detection Items:
      - Intensity: High/Low/No Signal
      - Chip Luminance: Average/Total
      - Standard Deviation/Coefficient of Variation (CV)
    • Chip Size ≥ 10 μm, Pitch ≥ 20 μm, Gap ≥ 3.5 μm
       
  • AOI
    • Detects surface defects, cracks, pattern misalignment, and positioning errors
      Minimum detectable chip size: 1.5 μm
      Achieves composite judgment based on AOI and PL information
       
  • Spectrum Analysis
    • Key spectrum parameters:
      - Wp (Peak Wavelength)
      - FWHM (Full width at half maximum)
      - II (Integrated intensity), Ip (Peak intensity)
    • Pitch Resolution
      - 0.5 mm (4-inch wafer), 1.0 mm (6-inch wafer), 2.0 mm (8-inch wafer)
