Ju and I have cleaned the nozzle with acetone and run about 9 dummies total.  The dummy wafers tend to look alright, and then the good wafer looks aweful, with a huge spotch in the middle.  I have noticed that the suck back tdoes not seem to be very strong and on this last wafer it was obviously not functioning properly.
