There was a short ~30min campus water outage, but it has now been restored. |

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. |

Chemical usage/processing is now allowed as normal. |

Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did. |

So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line. |

The tool is down due to the intermittent head crash issue. I am waiting to hear back from the vendor as to when we will have someone out to look at it. --Lee |

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. |

=====YES EcoClean: 3kW only===== |

| ⚫ | |||
I swapped out the RF generator and the tool is working again. I am getting repeated CCP warnings for the 0.7kW recipes so we will need to look into that further. |
|||
| ⚫ | |||
System is up for 3kW recipes only. |
|||
We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests. |
|||
I will send out an update once we have one. |
|||
DO NOT run 0.7kW recipes until further notice!! |

Chemical processing is UP
There was a short ~30min campus water outage, but it has now been restored. Chemical usage/processing is now allowed as normal. // Demis D. John 18:36, 16 June 2025 (UTC)
Raith EBL Update
Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did.
So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line.
We are close, very close, but still not quite there. And I am really sorry that is still the case… -Bill // Demis D. John 22:53, 13 June 2025 (UTC)
