摘要： A process of an extreme ultraviolet lithography (EUVL) is disclosed. The process includes receiving an extreme ultraviolet (EUV) mask with multiple states. Different states of the EUV mask are assigned to adjacent polygons and a field. The EUV mask is exposed by a nearly on-axis illumination (ONI) with partial coherence σ less than 0.3 to produce diffracted lights and non-diffracted lights. Most of the non-diffracted lights are removed. The diffracted lights and the not removed non-diffracted lights are collected and directed to expose a target by a projection optics box.

摘要： A mask and method of fabricating same are disclosed. In an example, a mask includes a substrate, a reflective multilayer coating disposed over the substrate, an Ag2O absorber layer disposed over the reflective multilayer coating, and a tantalum-containing absorber layer disposed over the Ag2O absorber layer. The tantalum-containing absorber layer is disposed over the Ag2O absorber layer outside a mask image region of the mask, such that the mask image region of the mask is free of the tantalum-containing absorber layer. In an example, the tantalum-containing absorber layer is disposed over the Ag2O absorber layer adjacent to the mask image region.

摘要： A method for repairing phase defects for an extreme ultraviolet (EUV) mask is disclosed. The method includes receiving a patterned EUV mask with at least one phase-defect region, determining location and size of the phase-defect region, depositing an absorber material to cover the phase-defect region and removing a portion of the patterned absorption layer near the phase-defect region in the patterned EUV mask to form an absorber-absent region.

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.
