=====E-Beam #2 Heater is down - Update===== |
|||
I am fairly certain the heater controller has failed. I have spoken with the vendor and they are looking into it, but we will most likely have to send the unit in. I will push to have a replacement controller sent instead, but since this is a warranty repair they will probably want to eval it in-house. I would plan for it to be down for at least a couple of weeks. I'll send out an update once I have more info. |

contacted our vendor for an update and was told that the parts should ship by this Friday. If all goes well the tool should be up mid next week. |

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. |

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. |

Good news is we have repaired and reinstalled the hoist, thanks Mike B. and Bill. I have tested it and everything looks good. |

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. The mount is back at the machine shop getting honed out. I should have it back to test late today/early tomorrow but it may have to go back again. 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.
