Method of making an extreme ultraviolet pellicle
Abstract:
The present disclosure relates to a method of forming an extreme ultraviolet (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. A pellicle frame is attached to an upper surface of the substrate, and the substrate is cleaved along the cleaving plane to form a pellicle film attached to the pellicle frame. The method forms the pellicle without using a support structure, which may block EUV radiation and cause substantial non-uniformities in the intensity of EUV radiation incident on an EUV reticle.
