<div> </div>
<div>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%.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>The shortage is starting to cause delays on key government programs, so I'd very much appreciate any insight from this group.</div>
<div> </div>
<div>Thanks for your advice!</div>
