    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 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 photomask having a machine-readable identifying mark and suitable for manufacturing integrated circuit devices and a method for forming the photomask and identifying mark are disclosed. An exemplary embodiment includes receiving a design layout corresponding to a pattern to be formed on a photomask blank. A specification of an identifying code is also received along with the photomask blank, which includes a substrate, a reflective layer, and an absorptive layer. A first patterning is performed using the design layout. A second patterning is performed using the specification of the identifying code.

    摘要: A method for reducing layer overlay errors by synchronizing the density of mask material in the frame area across the masks in a set is disclosed. An exemplary method includes creating a mask design database corresponding to a mask and containing a die area with one or more dies and a frame area outside the die area. Fiducial features within the frame area are identified, and from the fiducial features, an idle frame area is identified. A reference mask design, which corresponds to a reference mask configured to be aligned with the mask, is used to determine a reference density for the idle frame area. The idle frame area of the mask design database is modified to correspond to the reference density. The modified mask design database is then available for further use including manufacturing the mask.
