Cells

The complex processing steps in cell manufacturing have to be operated efficiently and therefore being controlled permanently. Our customer-specific inspection modules help you to detect faulty cells/wafers and production drifts as soon as possible.

• Printinspection (Laser control, geometry, ARC)
  With resolutions down to 10 µm each printing step (front contact, back contact, back field) or laser process can be controlled inline. The geometries of cells are measured for detecting errors like chippings, cracks and breakages as well as contaminations. The ARC inspection tasks ranges from a simple colour classification to the determination of optical parameters (coating thicknesses, refractive indices, extinction coefficients).
  
  • APUS

• Microcracks
  The transillumination of wafers with infrared light makes microcracks
  reliably visible. By the use of new technology false positives will be
  minimized.
  
  • ANTARES
  • TAURUS

• Quality tracking
  By using the natural grain structures one has the possibility of
  tracking the wafer during the manufacturing and assigning them to their
  position in that block.
