We were able to start running recipes last night but we found the C4F8 MFC wasn’t controlling. I’ve ordered a new MFC that’s due to be on site Tuesday morning. If all goes well the tool should be up that afternoon. |

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. |

Some additional work is needed on the replacement board that we are waiting on. I have been informed that it will not be shipping until after the 20th (no solid date). |

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. |

I will send another notification when everything has been worked out, and I am ready to schedule the installation. |

Card/Iris scanner access is still currently enabled. However we will be moving to a smartphone-based access system.

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)
SignupMonkey + Wiki: Off-Campus Access

ICP1 Down
The board we were waiting on arrived, but it did not resolve the tool issue. We are working with Panasonic on the next steps. //Vraj Mehalana 14:17, 1 March 2024 (PST)
