Definitions
- the raw material for crystallization is melted by the heater 62, the pressure in the chamber 69 is reduced, and then the gas is left in the melt 63 for a while to allow the gas in the melt 63 to be sufficiently released.
- An inert gas is introduced from above the chamber 69 to make the inside of the chamber 69 a reduced pressure inert gas atmosphere.
- the method for pulling a single crystal according to the present invention (2) includes the method for pulling a single crystal described above.
- the single crystal pulling apparatus (10) according to the present invention is the above single crystal pulling apparatus.
- FIG. 5 is a cross-sectional view schematically showing the single crystal pulling apparatus according to the embodiment (2).
- L3 ⁇ 4I4 is a cross-sectional view schematically showing the single crystal pulling apparatus according to the embodiment (3).
- FIG. 4 is a cross-sectional view schematically showing a single crystal pulling apparatus 30 according to the embodiment (3).
- the single crystal pulling apparatus in which the holding tubes 44 and 51 are added to the holders 44 and 52 has been described, but according to another embodiment, In the single crystal pulling apparatus, the heat retaining tubes 41 and 51 are added to the holders 44 and 52, and the laser generator 11 and the infrared rays described in the embodiments (1) to (3) are used.
- the line generating / introducing devices 21 and 31 may be provided.
- the heat retaining tubes 41 and 51 are made of quartz, the laser beam 13 and the infrared ray 25 pass therethrough. Therefore, the seed crystal 1 is formed by the laser generator 11 and the infrared ray introducing and introducing devices 21 and 31. 5 can be heated, and since the heat retaining tubes 41 and 51 have excellent heat retaining properties, the temperature of the seed crystal 15 can be increased more efficiently.
- Diameter about 300 mm (12 inches), length: about 100 mm, weight: about 270 kg
