I am pretty much now used to getting materials only months from expiry from all sources.

Subject: [labnetwork] Alternative distributor for SPR 955?
Attention : courriel externe | external email
Dear Labnetwork,
Does anyone purchase SPR 955 (or any other Shipley/Dupont products) from a distributor other than Kayaku? We have had numerous issues with different materials. In this case, we need to either find a different distributor or begin qualifying another resist, probably both. The current issue is that we purchased a gallon of SPR955 which was ?in stock.? It arrived last week with an expiration date of 7/8/23. Kayaku?s response was that they were required to ship what they had on hand first and would ask for an extension to the expiration date from the manufacturer. I am still hoping for a better response and solution than that but need to find an alternative in the meantime.
If anyone works with a different distributor for Shipley resists, I?d love to hear your experience. I?ll share the final solution from Kayaku and summarize any responses for alternatives.
Thank you,

Hello labnetwork,
My group is looking to recruit a microscopist to help us manage and operate a new TEM. A description of our lab and the position are below, it would be great if you could circulate this appropriately to help us recruit a great microscopist!
Best,
-Nathan
The Quantum-Nano Core Fabrication and Characterization Facility (QNFCF) at the University of Waterloo is seeking to recruit a Senior Facility Microscopist. The successful candidate will be responsible for operation and training on our newly installed JEM-F200 S/TEM system equipped with EDS and EELS spectrometers. They will also play a key role in the operations of complimentary equipment for sample preparation including a ZEISS Auriga FIB-SEM system.
The Quantum-Nano Core Fabrication and Characterization Facility (QNFCF) is series of core facility research labs serving the University of Waterloo community as well as external academic and industrial clients. QNFCF labs are professionally staffed and boast over 100 pieces of installed equipment serving approximately 250 individual users per year under 80 groups. The centrepiece of the QNFCF operation is our 8000 sq.ft cleanroom boasting ISO 4/5/6 certified process bays.
Electron microscopy resources under the responsibility of the Senior Facility Microscopist (including our new JEM-F200 S/TEM) represent an important new capability for the QNFCF lab and the University of Waterloo community. These resources are installed in the Quantum Nano Centre building?s metrology suite on the concourse level of the building. The metrology suite labs are purpose built for electron microscopy and other metrology resources and have exceptionally low levels of electrical and acoustic noise (meets VC-G criteria).
The Senior Facility Microscopist is a full time staff position with immediate access to all staff benefits including a defined benefit pension plan.
For more information and to apply please refer to the job description in the link below:

Subject: [labnetwork] Heidelberg MLA150 SU-8 Exposure Dose
Message-ID: <SA1PR01MB6544488F2AF7FBED45495CE2F322A@SA1PR01MB6544.prod.exchangelabs.com>
Dear Labnetwork,
We have found that exposure of SU-8 on our MLA150 tool (using the 375nm laser) seems to require very high doses. Even thin ~500nm thick films (using SU-8 2000.5) have required doses on the order of 1200mJ/cm2 to fully expose. This is 15-20x the recommended dosage from both the datasheet and what we estimate is the exposure dose used on our filtered contact aligners. Thicker films follow the same trend, but not necessarily in a linear fashion (5?m films require ~2000mJ/cm2).
I am sure the bump from 365nm to 375nm plays a role, but the magnitude of the change seems excessive. FWIW, our other negative resists (eg. nLOF2020) seem to expose properly at reasonable doses.
Has anyone else experienced this? Does anyone have an explanation or any processing suggestions for using SU-8 with an MLA?
Thanks,
