Abstract
A methodology is presented using thermal analysis to aid lithographic process development and/or photoresist evaluation. The temperature ran ges of the reactions occurring in the photoresist film during baking c ycles, and the apparent glass transition temperatures (T-g) of the fil ms are determined, and used for prebake and post-exposure bake optimis ation. The methodology is applied for several commercial photoresists, namely UVIII, XP 90166*, EPR*, and AZ 5214*, for which optimum bakin g temperature ranges are determined.
