发明名称 METHOD FOR PRODUCING SINGLE CRYSTAL AND PULLING DEVICE
摘要 <p>A method for producing a single crystal by pulling the single crystal with a wire according to the Czochralski method, wherein temperature around an end of joint part of the wire and a seed crystal holder is controlled so as not to exceed 1200 DEG C, preferably 800 DEG C, at any time, and material of the wire is one selected from tungsten, stainless steel and molybdenum, and a pulling apparatus therefor. According to the present invention, there can be provided a method in which temperature around an end of joint part of a wire and a seed crystal holder is controlled so as not to exceed a temperature at which material degradation of the wire begins during the period of from seeding to an early stage of the pulling, and a pulling apparatus therefor. <IMAGE></p>
