When the vendor came in to install the new top heater he wasn't able to get the z-axis (elevator motor) to move. He was able to install the new heater and do a PM on the rest of the tool. We are ordering a new z-axis controller on the recommendation of the vendor. If all goes well this should solve the issue and make the bonder fully operational. I'll send out an email once the new controller has been installed. |

However, the repaired bell jar mount is not sliding down the hoist pole like it should. Since the repair involved some welding to the collar that slides down the hoist pole, we surmise that the concentricity was affected by the heat.

Once it is able to slide on properly the tool should be up shortly thereafter. |

ASML: intermittent alignment failures
I have determined that the laser used for Alignment is failing, the power is low and it flickers.
We will order a replacement ASAP and schedule an ASML engineering visit to install + calibrate a new one.
In the mean time, I'm sorry to say that you will see intermittent "reject" wafers. Please see email for info on recovering from this error.
