I am trying to develop a repeatable liftoff process using LOR10B and an 1800 series positive resist for use with 1:1 microdev developer (necessary for material compatibility). The trouble arises in the repeatability of the process. Time of development varies significantly between runs with no process parameters changing yielding far too much undercut for our application. We have the LOR thinner and have by trying to work with that as well as full thickness LOR. Does anyone have a repeatable process or suggestions?
