摘要： This invention provides a method for manufacturing silicon single crystals. The method is capable of eliminating void defects existing in deep regions of a silicon single crystal despite the size of the silicon single crystal. The silicon single crystals according to this invention are pulled the radius of a ring-shaped oxidation induced stacking fault (OSF ring) of a wafer is larger than half the radius of the wafer during the process of thermal oxidation treatment.

摘要： In the crystal growth rate (V), there is such a permissible range that the given quality of silicon single crystal can be maintained. This permissible range is determined in advance. The log data of crystal growth rate (V) is measured in the pulling up of silicon single crystal, and using the log data, the actual value of crystal growth rate (V) is determined. The actual value is compared with the permissible range. Any region of silicon single crystal corresponding to crystal growth rate (V) falling within the permissible range is judged as being a conforming region satisfying given standards, while any region of silicon single crystal corresponding to crystal growth rate (V) falling outside the permissible range is judged as being a defective region not satisfying given standards.

摘要： A Czochralski single crystal manufacturing apparatus uses multiple heaters to improve the controllability of crystal diameter. The power supplied to the multiple heaters is controlled so as to bring the pulling up speed close to a predetermined speed set value, and so as to bring the heater temperatures close to predetermined target temperature values. The ratio of electrical power between the heaters is controlled to agree with a predetermined power ratio set value which varies according to the crystal pulling up length, and the heater temperatures change along with this change, which causes disturbance to the diameter control. To compensate for this, heater temperature changes along with the power ratio set value change are taken into account in advance in the temperature set values. Accordingly, along with change of the power ratio set value, the temperature set values change to values appropriate for the current power ratio set value.
摘要翻译： Czochralski单晶制造装置使用多个加热器来提高晶体直径的可控性。控制提供给多个加热器的功率，以使提升速度接近预定的速度设定值，并使加热器温度接近预定的目标温度值。加热器之间的功率比被控制为与根据晶体拉长长度变化的预定功率比设定值一致，并且加热器温度随着该变化而变化，这导致对直径控制的干扰。为了补偿这一点，预先在温度设定值中考虑加热器温度随功率比设定值变化的变化。因此，随着功率比设定值的变化，温度设定值变为适合于当前功率比设定值的值。
