=====Raith Velion DOWN===== |
||
The Raith Velion FIB tool is currently down while the AuGeSi source is replaced. Expected return to general use May 5th. |
|||
After installing our backup spool the system ran for approximately 15 minutes and then failed again due to a leak in the chamber. I took apart the chamber and found a crack on the backup spool. |

===== SignupMonkey + Wiki: Off-Campus Access===== |
|||
I spoke to an engineer at PlasmaTherm and he told me this issue was indicative of a failing lamp (or lamps) that was causing a large delta of heat across the ceramic spool. |
|||
Due to a DDoS attack affecting the Signupmonkey server, we have restricted access to the website to US locations only, including both the Nanofab Wiki and Signupmonkey. |

I requested to have a couple new spools to be overnighted but they most likely won’t ship out until Monday. I tested the lamps and found two that were pretty heavily oxidized on the leads. |

I’ll install all new lamps and the new spool when it gets in next week. |

=====New Gowns: Toolbelts purchases===== |
||
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. |
|||
Replaced bad PLC controller on Depo beam. I then tested the beam with a 15 min gridclean recipe without issue. |
|||
I then ran an SiO2 dep, and a 1 hour gridclean without issue. |
|||
Two vendors for cleanroom belts we are using are listed here, you may request others: |
|||
System UP - Mike Barreraz |
|||
* [https://www.terrauniversal.com/tool-belt-pocket-49in-waist-white-altessa-grid-uniform-technology-4954-60a.html Uniform Technology Tool Belt] - note the waist size, the 49” belt fits up to ~36-38” waist. |

=====Focused Ion Beam (Raith Velion) - TOOL DOWN for Raith Service===== |
|||
Raith service need to work on the Velion a little longer than anticipated. I'll keep the tool down until 2pm tomorrow (Tuesday). I'll send further updates if anything changes. |

Optical AF has been calibrated and Defocus + Dose values are the same as before. PneuAF has not been checked et, but we expect a shift in PneuAF Defocus due to the Pneumatic nozzle replacement. |

=====Stepper #3 (ASML DUV) - Down, update===== |
|||
The alignment laser has now fully failed (no laser output at all), so we can't perform any exposures. |
|||
ASML engineers will be on site Monday Tues (Sept 16th) to perform the repair. |

||
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. |
|||
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. |
|||
I will send out an update once we have one. |

=====YES is available===== |

The error has been cleared and I ran a shorter 5 minute recipe with no warning/error. |
|||
This seems to be exclusive to the longer (8+ minute recipes), which are throwing warnings for every wafer run this long. It also appears that running 3 wafers on a longer recipe will result in an error and aborted run on the 3rd wafer. We are just going to have to live with this until we have our other generator back. So until then, please limit the longer runs to 2 wafers max. If you have more than 2 wafers to run on a longer recipe then wait about 5-10 minutes in between batches. |
