摘要： The deposition and condensation of evaporated matters and reaction products are controlled to prevent an exhaust pipe from clogging by allowing evaporated matters and reaction products produced in a furnace to be exhausted without contacting a graphite crucible and a heater and by keeping an exhaust pipe itself at high temperature, the exhaust pipe is prevented from being formed into SiC to improve the durability of the exhaust pipe, and a thermal single crystal can be pulled up in high quality by preventing a change in thermal expansion coefficient. An exhaust pipe constituted of fewer materials will reduce production costs. A heat shield (12) formed of an insulation material is provided on the outer side of a heater (6), and a plurality of exhaust pipes (20) are provided between the heater (6) and the heat shield (12). The plurality of exhaust pipes (20) are allowed to communicate with a plurality of exhaust ports (8b(22b)) provided in the bottom of a chamber (1).

摘要： A process for producing a single crystal according to the Czochralski method wherein a polycrystalline raw material is put in a crucible, then the polycrystalline raw material is melted by heating by means of a heater arranged so as to surround the crucible and thereafter a seed crystal is fused to the raw material melt and pulled up to thereby effect single crystal growth, characterized in that in the growth of single crystal whose resistivity has been regulated by boron doping, the single crystal growth is performed while controlling the maximum temperature of the crucible at 1600°C or below. In the production of boron-doped single crystal having high gettering capability, the single crystal can be produced by the above process at high productivity and at low cost while inhibiting any dislocation generation.
