    Abstract: A reticle and a method of fabricating the reticle are provided. In various embodiments, the reticle includes a substrate, a patterned first attenuating layer, a patterned second attenuating layer, and a patterned third attenuating layer. The patterned first attenuating layer is disposed on the substrate. The patterned second attenuating layer is disposed on the patterned first attenuating layer. The patterned third attenuating layer is disposed on the patterned second attenuating layer. A first part of the patterned first attenuating layer, a first part of patterned second attenuating layer, and the patterned third attenuating layer are stacked on the substrate as a binary intensity mask portion.

    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.

    Abstract: A reticle for use in an extreme ultraviolet (euv) lithography tool includes a trench formed in the opaque border formed around the image field of the reticle. The trench is coated with an absorber material. The reticle is used in an euv lithography tool in conjunction with a reticle mask and the positioning of the reticle mask and the presence of the trench combine to prevent any divergent beams of radiation from reaching any undesired areas on the substrate being patterned. In this manner, only the exposure field of the substrate is exposed to the euv radiation. Pattern integrity in neighboring fields is maintained.
