PSFM Data!™

Our PSFM Data!™ Focus Analysis software package is specifically designed to be used with our Phase Shift Focus Monitor Reticle. The software frees the user from working with spreadsheets and provides many functions to the user. The software can parse the output from most overlay tools currently in use in the semiconductor industry and convert it to meaningful focus information.

User Inputs:

  • Raw ASCII overlay data / Litho tool job file
  • User defined focus/dose data
  • Interactive specification if exposure parameters


Function:

  • Easy-to-use focus/dose assignment function
  • PSFM Calibration and focus monitor
  • Focus, tilt, astigmatism analysis and more...


System:

  • MatLab-based application
  • Works on multiple operating system
  • No auxiliary spreadsheets required


Results:

  • Output data in ASCII or csv format
  • Calibration templates for SPC Monitor
  • Focus, tilt, curvature, astigmatism, flatness and wafer edge to center comparison


Command line version available:
In addition to the graphical user interface version described above, we have also developed a command line version that fully integrates calibration and routine focus monitoring into the fab statistical process control system.
