  Please try these things in this order.

  1. Try CTRL C followed by A and Enter.  This will abort any command that may have hung up. Fallow instructions ( tall cabinet, printed paper on the wall)
  2. For Reticle Robot Hang Up:  See step 25 of start-up procedure

What to do in case of unplanned power outage.

  1. CR Staff will take care of the system in the morning.

What to do for an alignment error

  1. Verify that correct alignment key offset is being used (check sign convention)
  2. Verify that correct pass shift is being used (check sign convention)
  3. If you have DFAS alignment marks, perform a MAP job to verify alignment ( check sign convention)

What to do for focus resolution problems

  1. Perform a focus (EXPO) job using the same type of wafer that you will use for your real job and use the optimal focus offset determined from this job.  You may need to look at both exposure time and focus.
  2. If you have been running the same process and now have issues, run SETUP from the : prompt, following the instructions on the GCA Regular Maintenance Sheet.
