    摘要: A mask, method of fabricating same, and method of using same are disclosed. In an example, a mask includes a substrate and a reflective multilayer coating deposited over the substrate. The reflective multilayer coating is formed by positioning the substrate such that an angle α is formed between a normal line of the substrate and particles landing on the substrate and rotating the substrate about an axis that is parallel with a landing direction of the particles. In an example, reflective multilayer coating includes a first layer and a second layer deposited over the first layer. A phase defect region of the reflective multilayer coating includes a first deformation in the first layer at a first location, and a second deformation in the second layer at a second location, the second location laterally displaced from the first location.

    摘要: A method and system for measuring layer overlay and for inspecting a mask for defects unrelated to overlay utilizing a singe comprehensive tool is disclosed. An exemplary method includes receiving a mask design database that corresponds to a mask and has a die area with a mask database feature. A mask image of the mask is received, and a comprehensive inspection system compares the mask image to the mask design database in order to detect mask defects that are not related to layer alignment. The system produces mask defect information corresponding to the mask defects. The comprehensive inspection system also compares the mask image to the mask design database to determine a database-to-mask offset. From the database-to-mask offset, a mask overlay characteristic is determined.

    摘要: A reflective mask is described. The mask includes a low thermal expansion material (LTEM) substrate, a conductive layer deposited on a first surface of the LTEM substrate, a stack of reflective multilayers (ML) deposited on a second surface of the LTEM substrate, a capping layer deposited on the stack of reflective ML, a first absorption layer deposited on the first capping layer, a main pattern, and a border ditch. The border ditch reaches to the capping layer, the second absorption layer deposited inside the border ditch, and the second absorption layer contacts the capping layer.
