WCS (Wafer Contamination Scanner):

Powerful, fully automated wafer metal-contaminant detection System. Developed in collaboration with a major semiconductor Company.

Key characteristics include the following:

  • Fully automated and equipped with EFEM, automatic calibration for quantitative analysis
  • Patented scanning nozzle works on various wafer surfaces including hydrophobic and hydrophilic surfaces, patterned wafer and glasses.
  • Chemical supply system that automatically residue removal, which improves safety.
  • Flexible scan mode (i.e. full, radial, sector, chip mapping) and can be customized
  • Higher etching speed from its improved nebulizer and spraying knife

WCS (Wafer Contamination Scanner) M300:

WCS-M300 utilizes ICP-MS (Inductively Coupled Plasma Mass Spectrometry) for further detecting and characterizing metal trace on wafer surface. Agilent sensor used (others sensors can be adopted).

  • Inductively coupled plasma ionizes the sample.
  • Metal contaminant detection can detect down to one part per trillion
  • Detection Limit-1X107 atoms/cm2 on 300mm wafer
  • Survey Limit-over 60 elements in a single survey.

Scanning:
