摘要: Method for manufacturing a large columner silicon single crystal having a diameter of 12 cm-30 cm by pulling up a crystal, growing, and rotating it in one direction, from molten silicon material in a quartz crucible rotating in the other direction. The inside of the quartz crucible is divided into two sections--the peripheral section for feeding and melting raw materials and the central section for growing and pulling the crystal--by means of a cylindrical partition. The material feeding and melting section and the partition are sufficiently covered by an insulating board to reduce radiant energy heat loss and to keep the temperature at least above the freezing point of the molten materials in order to prevent the molten materials from solidifying at or around the inner wall of the cylindrical partition.

摘要: A silicon single crystal manufacturing apparatus in which a partition member formed with at least one small hole through its lower part is arranged in a rotating quartz crucible so as to surround a large cylindrical silicon single crystal which is rotated and pulled. The whole or part of the partition member is made from cellular silica glass whose cell content (volume percentage) is between 0.01 and 15% or less than 0.01% but increased to 0.01 through 15% by the heat used for melting starting silicon material. Thus, the molten material contacting with the inside of the partition member is prevented from decreasing in temperature and solidification of the molten material from this portion is prevented.
