  • Patent number: 10401285
    Abstract: The present invention relates to an apparatus for measuring surface properties of a polishing pad which measures surface properties such as surface topography or surface condition of a polishing pad used for polishing a substrate such as a semiconductor wafer. The apparatus for measuring surface properties of a polishing pad includes a laser beam source configured to emit a laser beam, and a photodetector configured to detect scattered light that is reflected and scattered by the polishing pad, an optical Fourier transform being performed on the detected scattered light to produce an intensity distribution corresponding to a spatial wavelength spectrum based on surface topography of the polishing pad. The laser beam is applied to the polishing pad at such an incident angle that the laser beam does not reach a bottom portion of a pore formed in the surface of the polishing pad.

  • Patent number: 10172056
    Abstract: The invention provides a mobile communication system, a network node, and a mobile communication method, which can cause user equipment of a particular type to attach to a dedicated network regardless of whether or not the user equipment supports a low access priority indicator (LAPI). An MME (60) acquires subscriber information on UE (10) from an HSS (70) based on an attachment request from the UE (10) forwarded by an eNB (50), the subscriber information including availability for the UE (10) to use the dedicated network, and sends the eNB (50) a selection instruction to select the dedicated network based on the acquired subscriber information. When the eNB (50) receives the selection instruction from the MME (60), the eNB (50) determines a dedicated MME (60D) constituting the dedicated network, and transmits the attachment request from the UE (10) to the determined dedicated MME (60D).
