Abstract: A method for adjusting one or more dimensions of a photomask subsequent to etching of a defective pattern in the chrome-containing layer thereof is provided. The method includes subjecting the chrome-containing layer of a photomask to a wet etch process utilizing a solution comprising deionized water and ozone. The length of exposure is directly proportional to the degree of adjustment desired. Accordingly, the method of the present invention provides a way in which dimensions of a photomask may be adjusted by a small amount (e.g., a few angstroms) or more severely adjusted, for example, by 20-30 nanometers or more.

Abstract: An anode screen for a field-emission-display is formed by layering light-permeable conductive material and phosphor respectively over a transparent substrate. A plurality of holes are formed in the layer of phosphor to expose corresponding regions of the conductive material. In a further embodiment, the anode screen is disposed in spaced and opposing relationship to a cathode emitter plate that comprises a plurality of electron emitters. Pixel regions of the phosphor of the anode screen correspond to regions of the phosphor opposite respective electron emitters of the plurality of electron emitters. Preferably, each pixel region of the phosphor has a number of holes spaced equally about its periphery. In the preferred embodiment, six holes delimit a hexagon shape for their respective pixel region, wherein centers of the holes provide apexes of the hexagon.
