Troubleshooting

Process Issues
Vacuum Issues

Vacuum should be met when the correct chuck size is chosen and chuck/base seal correctly.

  • Is your chuck size is correct for your substrate?;
  • Is the chuck base properly screwed on, if the base is needed?
    • Carefully screw on the base, don't cross the threads! Also make sure to screw as tightly as the chuck allows, but not further. These parts are plastic and can easily deteriorate if abused.
  • Are all necessary o-rings installed?
    • This includes the o-ring for the chuck base. This sometimes gets stuck and accidentally removed when someone has changed the chuck size.
  • Is there residue on the chuck?
    • Wipe down the chuck with IPA. If the residue is significant, report as a tool problem on NEMO.
  • Is the chuck was installed on the spindle correctly?
  • Is your sample flat/ without holes?
    • Try using a bare silicon wafer. If this works, the issue is likely your sample. To spin-coat on problematic samples, contact QNF staff.
