Wafer inspection

Application Challenges:

  • High optical resolution needed (5 – 15µm/Px)
  • Outstanding image quality to detect sub pixel sized defects
  • Multiple light conditions required to allow for versatile failure detection
  • Challenging production throughout and cycle time

Your Chromasens solution:

  • 15,360 Px high resolution color and mono line scan camera
  • Master Slave synchronization of multiple cameras for robust image alignment
  • Multi Channel LED flash to enable acquisition of multiple illumination conditions in one scan
  • Modular setup for different wafer sizes
  • Perfect focused multiple camera system for defects resulting in high contrast
  • 5 MLux illuminance
  • Water cooling for clean room environment
  • RGB LED for coating inspection via interference effects
  • High luminance for bright field setup
  • Compact design
  • Ultra thin beam splitter in coaxial module with anti reflection coating for highest image quality
