Hi, I am trying to pattern metal tracks on glass wafer using laser without using a photolithography mask. Is there is process for that? Is there a photoresist that can be patterned by green or UV3 laser beams? kind regards Salam R. Gabran, MASc. Research associate, PhD. Candidate MIAMI - CIRFE Groups ECE Dept.
