    • A method for measuring the relative distance between a reference reflector installed above the melt surface and the melt surface when a silicon single crystal is pulled up from the material melt in a crucible by the CZ method. The method is characterized in that the silicon single crystal is pulled up while applying a magnetic field, the real image of the reference reflector and the mirror image of the reference reflector reflected from the melt surface are captured by detecting means, the captured real image of the reference reflector and the captured mirror image are separately processed, the relative distance between the real and mirror images of the reference reflector is computed from the processed images, and thus the relative distance between the reference reflector and the melt surface is measured. With this, a method for more stably and more accurately measuring the distance between the reference reflector and the melt surface is provided. ® KIPO & WIPO 2009
    • 一种用于测量在通过CZ方法从坩埚中的材料熔融物将硅单晶拉出时,安装在熔融表面上方的参考反射体与熔体表面之间的相对距离的方法。 该方法的特征在于,在施加磁场的同时上拉硅单晶,通过检测装置捕获参考反射体的实际图像和从熔体表面反射的参考反射体的镜像,捕获的真实图像 基准反射体和捕获的镜像被分别处理,从经处理的图像计算参考反射体的实像和镜像之间的相对距离,因此测量参考反射体与熔体表面之间的相对距离。 由此,提供了用于更稳定且更精确地测量参考反射器和熔体表面之间的距离的方法。 ®KIPO&WIPO 2009

    • This invention provides an apparatus for producing a single crystal and a method for producing a single crystal. The apparatus is provided with at least a chamber dividable into a plurality of parts, for producing a single crystal by a Czochralski method. At least one of the plurality of the divided chambers has a flow path for a circulating cooling medium in which the circulating cooling medium for cooling the chamber is circulated, and means for respectively measuring inlet and outlet temperatures in the flow path for the circulating cooling medium and the flow rate of the circulating cooling medium. In the apparatus for producing the single crystal and method for producing the single crystal using this apparatus, a calculating means for calculating the quantity heat removed and/or the proportion of the quantity of heat removed from the chamber, base on the measured values of the inlet temperature and outlet temperature and flow rate of the circulating cooling medium, is provided. Further, pull-up speed control means for controlling the pull-up speed of the single crystal based on the calculated quantity of heat removed and/or the proportion of heat removed is also provided. The above apparatus for producing a single crystal and method for producing a single crystal can produce a single crystal while easily stabilizing the quality of the crystal.
