New Issues 	
	
	
	

	
Nanospec1(Etch)- Down: User "gsosa" reports that keyboard does not respond. Rebooting 
	
and restoring system defaults does not help. Contacted Field Service for Tech Support or 
	
service call. 
	

	

	
Old Issues- Ongoing 	
	
	

	
ASML Stepper- Purge hood removed again due to contamination issue and damage to 	

	
wafer table optics. The following process restrictions are in effect: 1- No thick resist processing 
	
(3.0 microns and above) until further notice, 2- No processing with 3D align until calibrations 
	
are performed. 3D calibration posponed. Date still to be determined. 
	
YES Oven- Intermittent pumpdown problem. Fails to achieve setpoint. Continuing to monitor 
	
the system for worsening condition. Also need to make plans to leakcheck the chamber. Spare 
	
vacuum controller sent out for repair. Estimated turnaround time: 7 - 10 days 	

	
KSCoat -Problem: Robot wafer pickup at load station. OK to process 4" wafers. Still need 
	
to check 3", 5" 6" and 8" wafer sized and re-teach as needed.

does not pump down very well. Troubleshooting in progress.
