Title: Method of pulling silicon single crystal
Inventor: NISHIMOTO MANABU
IPC: H01L21/208
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To enable the pulling of even a single crystal having heavy weight by increasing the diameter of the necking part and efficiently forming the necking part in the pulling of a silicon single crystal. SOLUTION: A silicon single crystal is pulled by forming a necking part composed of a diameter-decreasing part and a uniform diameter part. In the case of forming the diameter-decreasing part by contacting a seed crystal with molten silicon, the temperature of the molten silicon is set to a level not to decrease the diameter at the lower end of the seed crystal when the seed crystal is brought into contact with the molten silicon and pulled up at a speed of 1.5 mm/min and the seed crystal is pulled up at a pulling speed of >=2.5 mm/min to form a necking part. The diameter of the uniform diameter part of the necking part is preferably 4.5-10 mm.  It is preferable to perform the operation to keep the pulling speed of the seed crystal within the range of 0.0-1.5 mm/min for >=30 sea at least once in the forming of the necking part to keep the solid- liquid interface in a downwardly convex form.
