Paper Abstract

A capped photoresist mask of Kodak 809 on PN with minimal undercut is developed. The advantage of leaving Kodak 809 cap is that it offers better erosion resistance in the chlorine-containing plasma. The undercut of PMMA is dependent on the incidence angle of ultraviolet light to the resist. A wide incident angle creates substantial undercut while a normal incidence produces very slight undercut.
