Patent ID: 7569332

Claim:
A processing method of a thin-film comprising the steps of: forming a predetermined pattern film or predetermined elements on a substrate or on a film formed in an upstream process; forming a transparent film over the formed predetermined pattern film or predetermined elements; forming a pattern-transferred film, having three-dimensional protruded shapes corresponding to shapes of the formed predetermined pattern film or predetermined elements, on the formed transparent film, said shapes of the formed predetermined pattern film or predetermined elements being transferred to said pattern-transferred film by utilizing difference in the amount of light reflected perpendicularly from surfaces of the substrate or the film formed in an upstream process and of the formed predetermined pattern film or predetermined elements; and forming an opaque film on said pattern-transferred film, the opaque film completely covering the three-dimensional protruded shapes of said pattern-transferred film and having three-dimensional shapes corresponding to the shapes of the formed predetermined pattern film or predetermined elements and appearing as protrusions, the three-dimensional shapes appearing in said opaque film as protrusions being used to refer themselves to the shapes of said predetermined pattern film or to confirm the position of said predetermined elements when forming another film on said opaque film.
