[labnetwork] Dow ebeam resist delays

[Franklin Monzon]

Hi All,
 
We at HRL are having enormous difficulty with procurement of ebeam resist from Dow, and I wonder if anyone else is having this problem. Specifically, we are trying to acquire XR-1541. We use 2%, 4%, and 6% formulations but are having special problems with 2%.
 
Lead times have increased generally in 2020 (perhaps for some good reasons!), but the distributors we work with now cannot even get a firm timeline from Dow. We told them we are willing to order larger quantities than usual but have been informed that that won't help.
 
The shortage is starting to cause delays on key government programs, so I'd very much appreciate any insight from this group.
 
Thanks for your advice!
FM
