    摘要: A melt-surface initial position adjusting apparatus which is suitable for use in a monocrystal growing system employing the Czochralski method to adjust the vertical position of the melt surface before the growing of a monocrystal. The apparatus can ensure a highly precise measurement of a crystal-diameter measuring device, thereby enabling a reduction in the costs of producing a monocrystal bar. Before the growing of a crystal, the vertical position (H) of the surface (16A) of a melt within a crucible is measured. The crucible is moved vertically on the basis of the measured value in such a manner as to maintain the distance (L) between the melt surface (16A) and an image sensor (28) for measuring the crystal diameter at a predetermined value.

    摘要: Disclosed is a method of controlling the diameter of a single crystal produced by the Czochralski method. The diameter of a tapered portion of the single crystal is controlled by controlling the temperature of a melt in a crucible and the rotational speed of the crucible. The control range of the rotational speed of the crucible is made narrower as the diameter of the tapered portion approaches closer to that of a body portion, and the rotational speed is made constant while the body portion is grown.

    摘要: An apparatus for measuring the diameter of a crystal in which an optical sensor scans along a sensing line which crosses at one point a luminous ring formed at the interface between a crystalline rod and a melt; the picture element position corresponding to a maximum luminance is discriminated when the optical sensor scans; the mean value of the picture element position is calculated over at least one revolution of the crystalline rod; and the diameter D of the crystalline rod at a portion thereof interfacing with the melt is calculated from the mean value and the level of the melt. Similarly, the minimum crystal diameter can be calculated by obtaining the picture element position corresponding to the minimum crystal diameter instead of obtaining the mean of the picture element position.

    摘要: The present invention is a method for producing a single crystal of which a whole plane in a radial direction is a defect-free region with pulling the single crystal from a raw material melt in a chamber by Czochralski method, wherein a pulling condition is changed in a direction of the crystal growth axis during pulling the single crystal so that a margin of a pulling rate is always a predetermined value or more that the single crystal of which the whole plane in a radial direction is a defect-free region can be pulled. Thereby, there can be provided a method for producing a single crystal in which when a single crystal is produced by CZ method, the single crystal of which a whole plane in a radial direction is a defect-free region entirely in a direction of the crystal growth axis can be produced with stability.
