    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.

    摘要: A method of fabricating a lithography mask with carbon-based-charging-dissipation (CBCD) layer is disclosed. The method includes providing a substrate, depositing an opaque layer on the substrate, coating a photoresist and depositing a charging dissipation layer on the photoresist. The photoresist is patterned by an electron-beam writing. The CBCD layer is removed during developing the photoresist.

    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.
