Abstract:
1. A method of forming a pattern on a photosensitive resin film, comprising: forming a processing-object film above a semiconductor substrate; forming a first patterned photosensitive resin layer on the processing-object film; implanting ions into the first patterned photosensitive resin layer, the sum (Rp+3dRp) of a projected range (Rp) for the ions in the first photosensitive resin layer and three times a standard deviation (dRp) of the projected range being greater than a thickness of the first patterned photosensitive resin layer; and forming a second patterned photosensitive resin layer on the ion-implanted first patterned photosensitive resin layer.
