    • PURPOSE:To prevent the breakdown and the falling of a seed crystal while said crystal is fixed by a holding device and pulled up, by inserting the seed crystal into a groove of the holding device and pressing it down by a supporting rod and a push rod when a single crystal is pulled up by a rotating and pulling up method. CONSTITUTION:When a single crystal is grown on the tip of a seed crystal and pulled up from a molten starting material by a rotating and pulling up method, the seed crystal 31 is shaped in the form of a wedge having about 5 degrees sharp angle. As a holding device of the seed crystal 31, a cylndrical base substance 21 is made of alumina ceramic and has a wedge groove 22 formed for inserting said crystal 31 at the lower part. A hollow part having a female screw part 26 on the inner surface from the top surface of the base substance 21 and a connecting hole 23 having a smaller diameter than the one of the hollow part at the lower part are drilled in such a way that said hole 23 is reached to the top of the wedge groove 22. The seed crystal is put in the groove 22 of the base substance 21, and a push rod 25 is inserted into the connecting hole 23 from the top. The top 25A of the push rod is pressed down by screwing a supporting rod 27 having male screw and the top of the seed crystal 31 is pressed by the tip of said rod 25. The seed crystal is fixed by the groove 22 and pullig-up of the single crystal is carried out stably without falling and damage.
    • 目的:为了防止晶体被保持装置固定并上拉时晶种的破坏和落下,通过将晶种插入到保持装置的槽中并用支撑杆和推杆 当通过旋转和拉起方法将单晶拉起时。 构成:当通过旋转和拉起方法在晶种的尖端上生长单晶并从熔融原料拉起时,晶种31被成形为具有约5度锐角的楔形。 作为晶种31的保持装置,圆柱形基体21由氧化铝陶瓷制成,并且具有形成为用于将下述部分的晶体31插入的楔形槽22。 在基体21的上表面的内表面上具有阴螺纹部分26的中空部分和直径小于下部中空部分的直径的连接孔23以这样一种方式被钻孔 孔23到达楔形槽22的顶部。晶种被放入基体21的槽22中,并且推杆25从顶部插入到连接孔23中。 推杆的顶部25A通过拧紧具有外螺纹的支撑杆27而被压下,并且籽晶31的顶部被所述杆25的尖端挤压。籽晶由凹槽22固定并拉出 的单晶稳定进行而不会下落和损坏。

    • PURPOSE:To enable the control of the temperature of molten liquid at the optimum level, and to prevent the failure in the seeding operation, by using a transparent seed crystal in Czochralski (CZ) process, and detecting the temperature of the molten liquid just below the crystal optically through the transparent seed crystal. CONSTITUTION:Both end faces 15, 16 of the seed crystal 13 are polished to obtain an optically transparent crystal. A transparent rod 10 is inserted in the center of the pulling shaft 14, the lower end 11 of the rod is made to contact with the end face 15 of the seed crystal 13, and the rod 10 is used as a light guide. The temperature of the molten liquid just below the seed crystal 13 is detected optically through the seed crystal 13 and the light guide. The temperature of the molten liquid 2 in the pulling of a single crystal by CZ process can be controlled to the optimum level by this process.
