Wafer take-over from robot to P/A failed (wafer not sensed). Retrieved stranded wafer and cleaned pre-aligner chuck, Re-tried users wafer 2 times with no success, Back of wafer looks OK and wafer floats on granite. Tried with maint test wafers- all handling OK. User wafer may be slightly warped. Did daily tests. System OK to use.
