4.3 Operation Rules 

1. If  the  equipment  alarms  during  operation,  do  not  try  to  fix  the  problem  by

yourself and should report to NFF staff immediately. 

2. Do not operate the equipment unless you are properly trained and approved by

NFF staff. 

3. Do not leave an on-going experiment unattended.

4. Do not run the process for more than 30 mins.

5. Enough  time  of  cooling  is  needed  before  unloading  the  wafers  or  specimens

from the chamber after process completed. 

6. Do not start the process while the door is still open.

7. Except  for  “main  menu”,  “Process  for  Engineering  menu”  and  “Diagnostics

menu”, do not click into other menus such as “Maintenance menu”. 

8. Do  not  stop  the  process  by  an  improper  way  during  normal  operation.  For

example,  turn  off  the  RF  generator  to  stop  the  process  during  normal 

operation. 

9. Do not change the machine settings without permission of NFF staff.

10. This  equipment  is  only  for  purposes  of  PR  stripping  and  Descum.  For  any

other request, please consult with NFF staff. 

4.4 Initial System Checks 

1. The RF generator is turned on by confirming that “AC ON” red light is on and

“REMOTE ENABLE” green light is on. 

2. The mechanical pump is turned on

3. The computer is turned on so the touch screen is functioning.

4. The chamber should be under atmosphere pressure.
