  • Publication number: 20200407870
    Abstract: A method of estimating an oxygen concentration in monocrystalline silicon, which is pulled up by a pull-up device having a hot zone with a plane-asymmetric arrangement with respect to a plane defined by a crystal pull-up shaft and an application direction of a horizontal magnetic field, includes, in at least one of a neck-formation step or a shoulder-formation step for the monocrystalline silicon: a step of measuring a surface temperature of a silicon melt at a point defining a plane-asymmetric arrangement of a hot zone, and a step of estimating the oxygen concentration in a straight body of the pulled-up monocrystalline silicon based on the measured surface temperature of the silicon melt and a predetermined relationship between the surface temperature of the silicon melt and the oxygen concentration in the monocrystalline silicon.

  • Publication number: 20040215351
    Abstract: A system for disposing of wastes, in accordance with the present invention includes a plurality of terminal devices located at sites in which steps in a waste-recycling process are carried out, a network, and a host server making communication with the terminal devices through the network. Each of the terminal devices transmits data indicative of a condition of waste in each of the steps, to the host server, and the host server compares the data in each of the steps to one another to judge whether the condition of waste changes in each of the steps.
