Web7 apr. 2024 · All these challenges are mainly driven by lithography. With the development of advanced photoresists (PRs), the resolution factor K1 in projection lithography reduces from 0.66 to 0.39, improving the resolution by 40% without the negative impacts on the depth-of-focus (DOF). WebPall lithography filters employ a range of membrane materials to effectively eradicate contaminants in lithography process chemicals. They eliminate the possibility of deleterious particulate contamination, gel microbridge defects, microbubble void defects, and metallic contamination onto the wafer surface.
