    摘要: A photomask cleaning apparatus including a stage supporting a photomask, a cleaning fluid supplying unit configured to supply a cleaning fluid to remove contaminants from the photomask, a cleaning fluid absorbing unit configured to absorb the cleaning fluid supplied from the cleaning fluid supplying unit; and a contaminant removing structure configured to provide a path through which the cleaning fluid flows between the cleaning fluid supplying unit and the cleaning fluid absorbing unit through a surface of the photomask on the stage, and to have an opening aperture through which the cleaning fluid is exposed onto the surface of the photomask so as to remove at least some of the contaminants is provided. Methods of cleaning a photomask are also provided.

    摘要: A phase shift mask having a first region and a second region in a transverse direction includes a transparent layer, a phase shift pattern disposed in the first region, a transmittance control layer pattern disposed in the second region, and a shading layer pattern disposed on the transmittance control layer pattern. The phase shift pattern has a first pattern including a transparent material and a second pattern including metal. The phase shift mask may prevent haze effects through a cleaning process using an alkaline cleaning solution.
