Abstract: The present disclosure relates to a method of forming an EUV pellicle having an pellicle film connected to a pellicle frame without a supportive mesh, and an associated apparatus. In some embodiments, the method is performed by forming a cleaving plane within a substrate at a position parallel to a top surface of the substrate. A pellicle frame is attached to the top surface of the substrate. The substrate is cleaved along the cleaving plane to form a pellicle film comprising a thinned substrate coupled to the pellicle frame. Prior to cleaving the substrate, the substrate is operated upon to reduce structural damage to the top surface of substrate during formation of the cleaving plane and/or during cleaving the substrate. Reducing structural damage to the top surface of the substrate improves the durability of the thinned substrate and removes a need for a support structure for the pellicle film.
