<p class="MsoNormal"><span style="font-size:11.0pt">Hi Matthew,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The MAEBL community has dealt with this for many years. We reached out to Dischem (Andy Thompson) and he is providing many of us Ebeamers in the US with our HSQ. He is actually in your backyard in western
Pa. He packages up HSQ into the same/similar thicknesses and solids content that Dow did. He also will make small quantities and ships fast. I just bought a 20mL bottle from him which works great for us. Happy to share more if you are interested. It’s
not cheap, but it’s inline with the trajectory of the HSQ from Dow before it skyrocketed. You could compare directly with a quote from him.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">I would like to solicit your feedback on HSQ options for ebeam litho. Our group has traditionally worked with Dow Corning’s XR-1541-002 HSQ, and it has fit our needs for many years. However, as our stock
is now reaching a reorder point, we have reached out to vendors for quotes only to find that pricing has increased to a level we could have never imagined (not to mention lead times on the order of 80 business days). With that in mind, we have been looking
at alternative suppliers, including EM Resist (distributed through Integrated Micro Materials) and Allresist (Medusa 82).

<p class="MsoNormal"><span style="font-size:11.0pt">If anyone has experience working with the EM Resist and Allresist products, we would appreciate any feedback you might you might have on how they compare to the XR-1541. For example, do you see any major
differences in resolution, adhesion, dosing, etch resistance, etc.? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">If you have other alternatives, we would love to hear about them as well, although, we do prefer to buy pre-mixed solutions as opposed to mixing dry HSQ with MIBK ourselves.
