Filmherstellungsverfahren und Einstellvorrichtung dazu

摘要

The invention concerns a method of producing protective films or the like used as protective covers for photomasks or reticles. To peel a thin film (6) off a substrate (5), a peeling jig (8) constituted by a flexible annular frame (2) with an adhesive (10) applied thereon is pressed against the thin film applied on the substrate; a portion of the peeling jig is grabbed after the peeling jig and the thin film are adhered together; and the peeling jig and the film are peeled off the substrate. Before adhering the peeled film onto a side end surface of a pericle frame (21), of the two edges of the pericle frame, at least the edge formed by an inside surface thereof and the side end surface thereof is chambered.
