  • Patent number: 10043678
    Abstract: The present invention relates to a slurry composition for reducing scratches generated when polishing the metal film in a manufacturing process of a semiconductor integrated circuit, by lowering frictional force so that a temperature of the composition which may rise during the polishing is lowered, the thermal stability of the slurry is improved and the size increase of particles in the slurry is suppressed, and a method for reducing scratches using the same. The method comprises the steps of applying a slurry composition for polishing a metal film to a substrate on which the metal film is formed, the slurry composition containing an organic solvent including a nitrogen atom and a glycol-based organic solvent; and making a polishing pad to be contacted to the substrate and moving the polishing pad with respect to the substrate, thereby removing at least part of the metal film from the substrate.

  • Patent number: 8305127
    Abstract: A data delay control circuit and method that can adaptively reflect changes in an operating environment, such as an operating temperature, an operating voltage and a manufacturing process of a semiconductor chip. The data delay control circuit is designed to be able to adaptibly delay data when an expected delay of a predetermined period should be required when the semiconductor chip is designed. The data delay circuit includes a clock oscillation unit that can reflect changes in a delay period of a delay cell and automatically adjust the delay period of the delay cell. Since the data delay circuit includes a monitoring circuit and a plurality of delay paths, the data delay circuit can provide a delay path having a desired delay value. Therefore, even when the operating environment of a semiconductor device changes, the data delay circuit can control the delay period of a data signal.
