Kevin, Dennis Grimard at MITnano would be a great resource to ask this question. |
Essentially, its going to cost more than you expect. Also, make sure you lock in rock solid commitment of long term support for infrastructure and equipment. |
Cheers! |

Dear Colleagues, |
At LSU, we are putting together a proposal to build a cleanroom on campus (our current one is 15 min away). Our VP of research has asked me to determine a rough budget for constructing a microelectronics cleanroom. Below are the itemized details: |
- Size: 2000 sqft of class 100 space and 2000 sqft of grey room space. Our current off-campus cleanroom is 2000 sqft. |
- Location: 5th floor (top floor) of chemistry building (total space of 5th floor is 12,000 sqft) |
- Current condition of space: 5th floor is unfinished, i.e., concrete floors with pipes coming from the ground and 10ft ceilings. |
I want to factor in the following costs: air handlers, toxic gas handling for PECVD, LPCVD, and ICP-RIE machines, and getting utilities to each tool, i.e., power, water, and N2. |
$8 million is the current number that people are tossing around. I would greatly appreciate the feedback on that value. I certainly don't want to underfund the project. Thanks! |
Regards, |
Kevin |

Subject: [labnetwork] HDD Best Practice |
Message-ID: <590390B9-BEB6-4FB7-AA4F-EC7FE04A1270@central.uh.edu> |
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, |

We have also found that keeping a cloned HDD *outside* the computer chassis is very important. |
Once a tool has been set up satisfactorily, we then take the tool down, clone the HDD onto a similar one (using external HDD cloners), and then keep the clone in a separate cabinet (anti-static etc). |
In addition, we have all user recipes, software folders backed up from the live tool computer to our network storage. |
So for restore - we can swap the cloned HDD back into the computer, |
And then copy the backed up network files to the computer. |
We had a power glitch result in damaging Both HDD?s (including raid backup) within our ASML computer)! |
