[labnetwork] Liquid nitrogen and argon shortage

[Mark Weiler]

Hi Manish,

It may be more related to a transport issue as described in article linked below...

... we have certainly had our own issues with its delivery, a lack of drivers, and changes to how our supplier operates.

Best Regards,

Mark

Our entire lab will be impacted by this and we will need to evaluate consumption of these gases for different tools in our Nano fabrication center and make priority for tools usage based on that. Nitrogen is used as a purge gas for pumps and equipment and we will be looking into tools that consume significant amount of nitrogen and how to minimize their use or use them more efficiently.
