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. |

After speaking with Olympus it looks like there is a problem with the polarizer that is interfering with basic system initialization. I'm waiting for the repair quote and will update everyone when we know more. |

The maintenance is completed and the tool is finishing up an O2 clean run. We are still seeing a 0.04-0.05 Pa actual pressure difference in the software (as before the maint work) which we will address tomorrow, as the tool needs time to reach base pressure. -- Lee Sawyer |

=====Oxford ALD+Ion Mill: UP===== |

The tool is useable and in its original condition. If you had a reservation under the previous tool designation it has already been moved over for you. |
|||
Chamber 1 is operational and available for use. However, only recipes that run at 300C are to be ran on the tool, as the current thermocouple is only calibrated for that temperature at this time. |
|||
Please use the original tool name on SUM to make all future tool reservations. |
|||
There is no longer a need for supplemental training. If you have been previously trained on the tool but not received the supplemental training, you can once again reserve and use the tool. |
|||
Please feel free to email me directly with any questions you may have. |

We are required to switch to new gowns in January. The new gowns won’t have pockets, but you are allowed to purchase cleanroom tool belts. Please ask staff for which tool belts you can purchase. |

Two vendors for cleanroom belts we are using are listed here, you may request others: |

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 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. -Aidan // Demis D. John 00:35, 8 December 2024 (UTC)

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)
