Title: Crystal growing method
Inventor: AKASHI YOSHIHIRO
IPC: C30B29/06
Filed: 1993-03-15
Abstract: PURPOSE:To include an impurity into a crystal at a definite concentration during the pull-up process and uniformize the microscopic distribution of resistivity (SR) in the crystal. CONSTITUTION:In the growth of a single crystal such as silicon, a solid layer is formed under a molten liquid layer and the temperature fluctuation at the crystal deposition interface is suppressed and the impurity concentration in the crystal is uniformized in both axial direction and radial direction by adjusting the rotational speed of a crucible during pull-up operation. The rotational speed of the crucible is preferably adjusted to <=1 rpm. The temperature fluctuation at the crystal deposition interface is suppressed by this process to decrease the variation in the growth rate of the crystal. Accordingly, the concentration of impurity included in the crystal is uniformized to enable the production of a single crystal having uniform SR in high yield.
