    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, a second absorption layer deposited inside the border ditch, and the second absorption layer contacts the capping layer. In some instances, the border ditch crosses the capping layer and partially enters the reflective multilayer.

    摘要: A method of patterning an integrated circuit including generating a thermal profile of a reticle is provided. The thermal profile of the reticle may illustrate heat accumulation (e.g., a temperature) in a EUV reticle due an incident EUV radiation beam. The thermal profile may be determined using the pattern density of the reticle. The reticle is irradiated with a radiation beam having an extreme ultraviolet (EUV) wavelength. A thermal control profile may be generated using the thermal profile, which may define a parameter of the lithography process such as, a temperature gradient of a thermal control chuck. The thermal control profile may be downloaded to the EUV lithography tool (e.g., scanner or stepper) for use in a process. A separate thermal control profile may be provided for different reticles.

    摘要: A photomask includes a low thermal expansion material (LTEM) substrate, a patterned opaque layer over the LTEM substrate, and a patterned capping layer over the opaque layer. The patterned capping layer includes a transition metal material for suppressing haze growth, such as metal oxide, metal nitride, or metal oxynitride. The material in the capping layer reacts with a hydrogenic compound from a lithography environment to for an atomic level hydrogen passivation layer. The passivation layer has superior ability to suppress photo-induced haze defect growth on the photomask surface, to improve production cycle time and reduce the production cost.
