Abstract
Methods of patterning films that enable visual identification of patterned films and the patterned regions on them, while still achieving minimally discernible optical differences between the patterned and unpatterned regions in devices incorporating the patterned films. Such methods can exhibit wide successful manufacturing operating windows and the patterned films are useful in electronic applications.
