Dear Jocelyn, I think the PEB temperature is o.k. (we use similar temperatures following the datasheet). The crosslinking starts widely at that temperature but is not really finished before you make a hard bake. If you want to remove the resist after plating I would prefer the negative working plating resists AZ 15 nXT or AZ 125 nXT: http://www.microchemicals.com/products/photoresists.html Best regards, Mit freundlichem Gruß André Bödecker Institut für Mikrosensoren, -aktoren und -systeme Universität Bremen Fachbereich 1 Otto-Hahn-Allee1 28359 Bremen Tel: 0421 218 62596 _______________________________________________ Hosted by the MEMS and Nanotechnology Exchange, the country's leading provider of MEMS and Nanotechnology design and fabrication services.
