New Issues
Laurel R- Problem: User "kcbalram" reports a broken wafer in process bowl.
SVGCoat- Problem: User "popomoo" reports 3612 resist not dispensing
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 this week but depends
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.
KS Coat- Problem: User "lindaohara" reports a coolant water flow problem. Investigated
and found the water pump to be bad. Motor is OK. Water pump replaced on 11/2. Good water
flow. Cannot reach setpoint of 21 degrees C.. Suspect bad chiller. Will investigate further.
