  • Publication number: 20200386357
    Abstract: The present invention provides a socket and a pipe joint which facilitate coupling and uncoupling of the socket and a plug and which can prevent the plug from jumping out of the socket in the uncoupling. In a socket 10 of the present invention, fluid in a built-in plug part 22 is released to the outside via communication holes 40 of a second base portion 18 and a through hole 51 of a third base portion 19 in a semi-inserted state. Accordingly, the pressure in a hole portion 34 does not become excessively high and an engaged part 42 is not unexpectedly pushed upward. Thus, an engagement portion 38 and a second engaged portion 26 can surely engage with each other. Hence, the plug 12 can be prevented from jumping out toward the front end side in the semi-inserted state.

  • Patent number: 10066313
    Abstract: After melting raw materials, a distance between a raw material melt surface and a heat-shielding member disposed so as to face to the melt surface is adjusted based on temporal changes in chamber inside conditions, such as the heater temperature at the time of completion of the seed crystal equilibration operation carried out after completion of the raw material melting procedure and/or lag time required for completion of the seed crystal equilibration operation following completion of the raw material melting procedure. As a result, single crystals can be produced efficiently and in high yield, and further, by controlling the crystal interior temperature gradient by modifying the distance between the melt surface and the heat-shielding member, it becomes possible to control the ratio V/G (V:pulling speed, G:crystal interior temperature gradient) to thereby produce single crystals free of crystal defects such as COPs and/or dislocation clusters.

  • Patent number: 9145620
    Abstract: A single crystal pulling apparatus comprises: a chamber; a crucible disposed within the chamber for containing a melt; a water-cooling means disposed within the chamber in such a manner as surrounding a single crystal pulled up from the melt in the crucible; water piping for feeding cooling water to and discharging the same from the water-cooling means; and supporting arms connected to the chamber for supporting the water-cooling means, wherein the supporting arms are disposed between the single crystal and the water piping. According to this configuration, the supporting arms can prevent the water piping from being damaged in the event of fall and collapse of the single crystal due to failure of the seed neck portion or in the event of rupture of the single crystal due to thermal stress, for instance.

  • Patent number: 8771415
    Abstract: By determining a control direction of a pulling-up velocity without using a position or a width of an OSF region as an index, a subsequent pulling-up velocity profile is fed back and adjusted. A silicon single crystal ingot that does not include a COP and a dislocation cluster is grown by a CZ method, a silicon wafer is sliced from the silicon single crystal ingot, reactive ion etching is performed on the silicon wafer in an as-grown state, and a grown-in defect including silicon oxide is exposed as a protrusion on an etching surface. A growing condition in subsequent growing is fed back and adjusted on the basis of an exposed protrusion generation region. As a result, feedback with respect to a nearest batch can be performed without performing heat treatment to expose a defect.

  • Publication number: 20090293802
    Abstract: By giving a shoulder portion height of at least 100 mm in growing silicon single crystals having a diameter of 450 mm (weighing up to 1100 kg) by the CZ method, it becomes possible to inhibit the occurrence of dislocations in the shoulder formation step to thereby achieve a yield improvement and increase productivity. Furthermore, when this method is applied under application of a transverse magnetic field with a predetermined intensity, the occurrence of dislocations can be further inhibited and, accordingly, defect-free silicon single crystals suited for wafer manufacture can be grown with high production efficiency. Thus, the method is best suited for the production of large-diameter silicon single crystals having a diameter of 450 mm, which are applied in the manufacture of semiconductor devices.
