ABSTRACT:
Photosensitizers containing saturated and unsaturated polycyclic compounds containing the cyclopentane-2-diazo-1,3-dione structural unit.
These compounds have their maximum u.v. absorption at around 248 nm, decompose into polar products upon irradiation, and can be used as photosensitizers in positive deep u.v. or excimer laser (248 nm) lithography. They are most preferably useful with deep u.v. transparent resins for forming photoresists.
