  • Publication number: 20190085433
    Abstract: A magnesium (Mg) alloy having lightweight and excellent thermal conductivity, and a heat sink including the magnesium (Mg) alloy are provided. The magnesium (Mg) alloy may include one or more alloy additive elements selected from the group consisting of silicon (Si), calcium (Ca), tin (Sn), yttrium (Y), iron (Fe), nickel (Ni), copper (Cu), cerium (Ce), cesium (Cs), antimony (Sb), cobalt (Co), thorium (Th), and silver (Ag). Some of the alloy additive elements may be dissolved in the magnesium alloy to form a solid solution. The alloy additive elements that form the solid solution at room temperature may account for 2 wt % or less, based on the total weight (100 wt %) of the magnesium alloy, and the alloy additive elements that do not form the solid solution may be in crystalline phases.

  • Patent number: 6449873
    Abstract: Disclosed is a dry cleaning apparatus and method using cluster for cleaning a surface of a specimen such as semiconductor wafer. The cleaning method first forms a neutral cluster no having polarity by passing a cleaning gas such as argon, nitrogen, or carbon dioxide gas through a sand glass-shaped nozzle. The formed neutral cluster is injected at an acute angle with respect to a surface of the specimen, thereby removing particles or organic remnants attached on the surface of the specimen without damaging the surface of the specimen.
