New Issues 	
	
	
	

	
None- 
	

	

	

	

	
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. Possible re-installation within the next 2 weeks 
	
but dependant on ASML's available resources 	
	
	

	
YES Oven- Intermittent pumpdown problem. Fails to achieve setpoint. Performed a leakcheck 
	
on 9/28). Identified a leak in the chamber( rear/lower right corner). Investigating options. 
	
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. 
	

	
EVG Spraycoater- User "jackson" reports that the system needs a new registration code. 
	
Request submitted. Will get the keycode today as per EVG F/S manager. 
	

	

	
	
	
	
	

	
Resolved Issues 	
	
	

	
SVG Coat1- Problem: User "bchui" reports that 220-7 resist is not dispensing. Reset the 
	
pump controller. 
	
ASML Stepper- Problem: Edge sensor on pre-aligner having issues detecting the edges 
	
on Glass/Quartz wafers. ASML F/S adjusted the edge sensor and verified with several samples 	

	
EVG Spraycoater- User "jackson" reports that the system needs a new registration code. 
	
Request submitted. Key-code entered to activate software. System tested OK.
