Hello, I just bought some plastic mask, and I attached them onto a glass plate. I want to use these mask for contact lithography on SU-8 layer. I am wondering if the SU-8 layer would stick to the plastic mask after exposure. Or should I use the opposite side of the mask (i.e. glass plate) for contact with SU-8 layer? But in this way, the lithography won't be the contact one. Does anyone has that experience? Please give me some advices. Thanks! -- Best Regards, Ruilin Zheng Address: Pen-Tung Sah MEMS Research Center, Xiamen University, Xiamen,361005, P.R.China
