  • Patent number: 10036947
    Abstract: Disclosed are a blankmask and a photomask, in which compositions of metal and light elements of a light-shielding film are controlled so that the light-shielding film can guarantee a light-shielding efficiency, increase an etching speed, become thinner, and have a minimum sheet-resistance. To this end, the blankmask according to the present invention includes at least a light-shielding film on a transparent substrate, and the light-shielding film includes a first light-shielding layer adjacent to the transparent substrate and a second light-shielding layer formed on the first light-shielding layer, in which the first and the second light-shielding film contains chrome (Cr) and molybdenum (Mo).

  • Patent number: 9851632
    Abstract: Disclosed is a phase-shift blankmask, in which a light-shielding film includes a metal compound and having a structure of a multi-layer film or a continuous film, which includes a first light-shielding layer and a second light-shielding layer. The second light-shielding layer has higher optical density at an exposure wavelength per unit thickness (?) than the first light-shielding layer. The first light-shielding layer occupies 70% to 90% of the whole thickness of the light-shielding film. With this, the blankmask secures a light-shielding effect, has an improved etching speed, and makes a resist film thinner, thereby achieving a fine pattern.

  • Patent number: 9551925
    Abstract: A blankmask and a photomask using the same are provided. The blankmask can be useful in preventing the loss in thickness of lateral, top and bottom surfaces of a pattern of a light shielding film or a phase shifting film after the manufacture of the photomask by forming protective film, which has an etch selectivity with respect to a pattern of a hard film or the light shielding film, on the light shielding film or the phase shifting film so that the loss of the phase shifting film formed under the light shielding film or the phase shifting film can be prevented when a process of removing the light shielding film disposed under the hard film or a pattern of the light shielding film is performed during a washing process and a process of removing a pattern of the hard film in a method of manufacturing a photomask, thereby securing uniformity in thickness.

  • Patent number: 9256119
    Abstract: Provided is a phase-shift blankmask in which a phase-shift layer is formed in at least two continuous layers or a multi-layer film and an uppermost phase-shift layer included in the phase-shift layer is thinly formed to contain a small amount of oxygen (O) so as to enhance chemical resistance and durability thereof. Accordingly, a phase-shift blankmask including the phase-shift layer having enhanced chemical resistance and durability with respect to a cleaning solution containing acid and basic materials, hot deionized water, or ozone water, which is used in a cleaning process that is repeatedly performed during manufacture of a photomask, may be provided using the uppermost phase-shift layer having the enhanced chemical resistance and durability.

  • Patent number: 8585957
    Abstract: A method of manufacturing nano-fiber non-woven fabrics is provided. The method comprises preparing a polyurethane solution by dissolving polyurethane in an organic solvent, producing an electrospinning solution by adding far infrared ray emitting particles, antibacterial inorganic particles, and deodorization inorganic particles to the polyurethane solution, and electrospinning the electrospinning solution to form the nano-fiber non-woven fabric. The far infrared ray emitting particles may be obtained by adding a metal oxide to ceramics and sintering the metal oxide-added ceramics. The antibacterial inorganic particles may be obtained by impregnating a zirconium-based carrier with silver ions. The deodorization inorganic particles may be obtained by impregnating a zirconium-based or a silica oxide-based carrier with an amine-based compound.
