Abstract: Provided are a phosphor for a plasma display panel (PDP) including: a zinc silicate-based phosphor represented by the formula of Zn2SiO4:Mn; and a continuous crystalline metal oxide layer composed of yttrium oxide (Y2O3) formed on the zinc silicate-based phosphor, and a PDP having a phosphor layer composed of the phosphor. The phosphor for a PDP has a continuous crystalline layer composed of a positively charged metal oxide such as yttrium oxide, and thus has better surface properties. The metal oxide layer acts as a protecting layer to prevent deterioration of the phosphor due to ion bombardment. When the phosphor is used to manufacture a green phosphor layer for a PDP, a green discharge voltage can be controlled to levels of red and blue colors due to a better surface charge property and a poor specific gradation discharge problem can be resolved.

Abstract: A method of generating a photomask order used to manufacture photomasks using a tooling specification generating system including generating a tooling specification by creating, modifying and/or deleting components of a logical operation that is represented by the tooling specification. Information required for the logical operation may be imported from an external source, such as a database, and/or may be chosen from look-up lists. Aliases for the operators that make up expressions in the logical operation may be modified as desired by the photomask customer. The format of the tooling specification may be verified by the photomask customer's computer system. The tooling specification is sent to a computer system of a photomask manufacturer in various proprietary and industry standard formats for analysis of the tooling specification, and the photomask design may be simulated using the tooling specification.
