Abstract:
A method for forming a thin film comprising the steps of:forming an optical transparent film on a support so as to cover a first thin film element and a marker thereon, flattening the optical transparent film, forming a resist-cover on the part of the optical transparent film above the marker by a photolithography process, forming a plate underfilm on the optical transparent film and the resist-cover, removing the resist-cover from the optical transparent film, fabricating a resistframe on the part of the optical transparent film including the plate underfilm above the first thin film element by a photolithography process on the basis of the marker which is visible via the optical transparent film from the removed part of the resist-cover, forming a plate film on the part of the plate underfilm enclosed by the resistframe, and patterning the plate underfilm alongside the patterned plate film after removing the resistframe.
