Most of our computers are connected to a Synology NAS with RAID 1 configuration in a private network. The Synology software Active to Backup Business does back up the Windows 7 and 10 computers and Macrium Reflect is used for Windows XP. Backups are run weekly and several versions are kept for few months. We also have an offline backup of the NAS. |
When a hard drive fails, a new one is installed and the computer can be booted from a recovery media and connects to the NAS to recover a backup. This has saved us from long downtimes few times. |

Hi All, |
Yesterday we experienced a HDD failure for our AFM. This event should have been prevented by the Raid Mirror with 2 HDD. Our setup where we just have a single working drive and a spare backup clone has been more successful. We are planning to move away from Raid Mirror. Anyone has expertise/experience here they can share? |
Thanks, |

Subject: [labnetwork] O2 8%/CF4 gas cylinder |
Message-ID: <6443ece4-9b28-096b-4a78-473408048db3@eng.ucsd.edu> |
Hello all, |
We have been having difficulty getting a cylinder of O2 8%/CF4. We |
placed an order in early November 2022 with Linde and have yet to |
receive a ship date for the material. We have three orders out, but need |
the material urgently. The shortest lead time we have found is 9 weeks. |
Does anyone have any contacts for purchasing this gas or other options |
for obtaining a cylinder of this gas? Is anyone else experiencing this |
type of lead time for gas cylinders? |
Thank you, |
John |

Hi, |
We are looking at adding a 5" mask holder from Entegris (A94-0215), but the |
minimum order is 8. Is anyone interested in going in together to share a |
minimum quantity order? We only need one. |
The price per unit is $643.26. |
Thanks, |

Subject: [labnetwork] Light filtering in photolithography bays |
Message-ID: <BY5PR09MB5442585854E48D959D031137BBDD9@BY5PR09MB5442.namprd09.prod.outlook.com> |
Hi all, |
LLNL recently changed out its cleanroom lighting to LEDs from fluorescent tubes. A few months later, we found we were having lithography issues - our resist is getting exposed under ambient light within the litho bays within 5-15 minutes. The lights in our litho bays all have ~30 year old plastic diffusers that snap on over the tubes, and these diffusers have a filter film inside. We speculate that the new LEDs may have photobleached the aging photosensitive pigments. Measurements of the light intensity in the cleanroom at 365, 405, and 435 nm indicate that our litho bays have just as much light at these wavelengths than our non-litho bays! |
-- As an alternative to filtering the light, has anyone found LED cleanroom lighting that does not emit in the >450 nm range? For example, form-compatible LED 'tubes' that only emit at ~580 nm (yellow)? |
