METHOD OF CUTTING A MEMBRANE

摘要

An organic membrane (2) is stretched over, or adhered to, a frame (3) or a substrate, and that part of the membrane (2) which extends out of the frame (3) or substrate is cut by bringing an injection syringe-like needle (1) into contact with, or approach to, the lateral end surface of the frame (3) or substrate and while moving the needle (1) along said lateral end surface, injecting an organic solvent from the needle (1) and dissolving said membrane (2) along the lateral end surface of the frame (3) or substrate. By this method, the organic membrane (2) can be cut without generating foreign matter such as cut dust.
