    Abstract: An extreme ultra-violet mask includes a substrate, a multi-layered mirror layer, a capping layer, a first tantalum-containing oxide layer, a tantalum-containing nitride layer, and a second tantalum-containing oxide layer. The multi-layered mirror layer is over the substrate. The capping layer is over the multi-layered mirror layer. The first tantalum-containing oxide layer is over the capping layer. The tantalum-containing nitride layer is over the first tantalum-containing oxide layer. The second tantalum-containing oxide layer is over the tantalum-containing nitride layer.

    Abstract: In a method of manufacturing a reflective mask, a photo resist layer is formed over a mask blank. The mask blank includes a substrate, a reflective multilayer on the substrate, a capping layer on the reflective multilayer, an absorber layer on the capping layer and a hard mask layer, and the absorber layer is made of Cr, CrO or CrON. The photo resist layer is patterned, the hard mask layer is patterned by using the patterned photo resist layer, the absorber layer is patterned by using the patterned hard mask layer, and an additional element is introduced into the patterned absorber layer to form a converted absorber layer.

    Abstract: A method of manufacturing an extreme ultraviolet (EUV) lithography mask includes forming an image pattern in an absorption layer of EUV mask blank. The EUV mask blank includes: a multilayer stack including alternating molybdenum (Mo) and silicon (Si) layers disposed over a first surface of a mask substrate, a capping layer disposed over the multilayer stack, and an absorption layer disposed over the capping layer. A border region surrounds the image pattern having a trench wherein the absorption layer, the capping layer and at least a portion of the multilayer stack are etched. Concave sidewalls are formed in the border region or an inter-diffused portion is formed in the multilayer stack of the trench.

    Abstract: A method and a system for inspection of a patterned structure are provided. In various embodiments, the method for inspection of a patterned structure includes transferring the patterned structure into a microscope. The method further includes acquiring a top-view image of the patterned structure by the microscope. The method further includes transferring the patterned structure out of the microscope and exporting the top-view image to an image analysis processor. The method further includes measuring a difference between a contour of the top-view image and a predetermined layout of the patterned structure by the image analysis processor.
