| 20100037532 | Cutting Tool - A cutting tool including a fine and uniform alumina-based substrate is disclosed herein. In an exemplary embodiment, the alumina-based substrate includes 0.1 to 25% by volume of one or more metal oxides, or 5 to 80% by volume of metal carbonitride and 0.01 to 10% by volume of one or more metal oxides. Metal constituting the metal oxide and the metal carbonitride is selected from the group consisting of elements from Groups III to VI (including La group and Ac group) of the periodic table, Mg and Co. The metal oxides added to alumina reside at the boundaries of alumina grains, thereby prohibiting the alumina grains from growing excessively during a sintering process. | 02-18-2010 |

| 20100216063 | Masks and methods of forming the same - Methods of forming masks. According to the methods, a target pattern is set. Generation of a side lobe caused by the target pattern is verified. A preliminary target pattern and a preliminary side lobe pattern are set, in the target pattern and a region where the side lobe is generated, respectively. An interference pattern map using the preliminary target pattern and the preliminary side lobe pattern is created. At least one of regions having a phase identical or opposite to that of a position of the preliminary target pattern in the interference pattern map is set to an interference auxiliary pattern. A mask using the interference auxiliary pattern and the target pattern is formed. | 08-26-2010 |
