In-Line Thin Film Manufacturing Diagnostics Tool

The In-Line Thin Film Manufacturing Diagnostics Tool is capable of characterizing the correlation of thin film manufacturing line to a known good sample in real time, for both defect detection and process control.

Features

  • Entire surface of web is inspected
  • Able to detect thickness defects and small deviations of layer parameters from design goals, permitting tight process control
  • Does not require large dedicated section of the manufacturing line for flexible PV lines, can be applied in pretty much any spot of the line where customer would want it
  • Does not require dedicated, vibration insulating setup, can be used anywhere
  • Allows for sufficiently fast online diagnostics and feedback for control of process
  • Expected pay-back time of ~ 1 year after the installation
