Greetings PF. In my lab, we are having trouble making correct photoresist films(over 100 microns, SU-8 photoresist). They typically are not hardening enough before exposure. We want to solve this problem quickly as this is starting to interfere with the project. I'm trying to find solutions to the topic on the web, but I would also appreciate some feedback from anybody who has done microfabrication. Any tips? Thanks in advance. I hope this is the right section to put it in-if it isn't, my apologies.
