  • Patent number: 9493677
    Abstract: Provided are a polishing composition for chemical mechanical polishing, a method of preparing the polishing composition, and a chemical mechanical polishing method using the polishing composition. The polishing composition which is a water-based polishing composition for planarizing a metal compound thin film including two or more metal elements includes nano-diamond particles as a polishing material and poly(sodium 4-styrenesulfonate) as a dispersion stabilizer for the nano-diamond particles in the polishing composition. Since the nano-diamond particles in the polishing composition have hydrophobic surfaces and poly(sodium 4-styrenesulfonate) effectively stabilizes the nano-diamond particles to prevent the nano-diamond particles from aggregating, excellent polishing characteristics for the metal compound thin film may be obtained due to the nano-diamond particles which have a nano size, high hardness, and excellent dispersibility.

    Abstract: An advanced reflexive structure system is disclosed. The reflexive system mimics the pain withdrawal reflex on which the human body relies. The reflexive system incorporates a continuous health and performance monitoring system via an embedded dielectric film, an adaptive composite structure based on shape memory composite material, and an intelligence system which will be interfaced with both the health/performance sensors and the adaptive structure. When activated shape memory polymer will recover its structural integrity via shape recovery and a reptation healing process. These features enable the use of SMP as an adaptive structure in the proposed reflexive system. The development of a reflexive system for structures will enable increased safety and security and demonstrate a better understanding of integrated performance systems.

  • Patent number: 8114178
    Abstract: The present invention relates to a polishing composition for a semiconductor wafer which is excellent in polishing property, and a polishing method. The polishing composition for a semiconductor wafer comprises colloidal silica consisting of non-spherical silica particles having a ratio of long axis to short axis of 1.5 to 15. The polishing method for a semiconductor wafer uses the polishing composition. The polishing composition can provide a remarkably high polishing rate compared with a polishing composition using spherical colloidal silica, and can provide good mirror-polishing without causing scratches. In addition, small alkali metal content enables reduction of adverse effects on a semiconductor wafer, such as residual abrasives after polishing.
