<p class="MsoNormal">Hello labnetwork,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have two questions:<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<ol style="margin-top:0in" start="1" type="1">
<li style="margin-left:0in">We recently received notice from Kayaku Advanced Materials they would stop distribution of SU-8 2000 series resists in early 2025. Is anyone aware of alternate suppliers?<u></u><u></u></li><li style="margin-left:0in">They have recommended new options based on desired thickness: <10 um (SU-8 3000, SU-8 TF 6000 series), 10 – 50 um (SU-8 3000 series), >50 um (SU-8 XFT75, SU-8 XFT100). Does anyone
have experience with these in comparison to the 2000 series? We assume we would need to redo our recipes but hoped to get some general insight from others.<u></u><u></u></li></ol>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Lastly, I used nanobot.chat to find a previous thread in the labnetwork archives from 2021. Is there a way to reply directly to that thread to keep the conversation together? I couldn’t find anything so that’s why I’m starting a fresh
one now.<u></u><u></u></p>
