Title: Jig for preventing bottom adhesion in pull-up of semiconductor single crystal
Inventor: ATAMI TAKASHI
IPC: C30B15/00
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the generation of bottom-adhesion trouble in the pull-up of a single crystal by forming a space divided into plural sections between the bottom of a container vessel and the bottom of a susceptor using a cylindrical leg having the lower shaft axis as the center axis. CONSTITUTION:A gap corresponding to the radius of a cylinder forming a leg part 10B is formed between the leg part 10B and the lower shaft 2 when viewed from the axial line because the cylindrical leg 10B is formed in such a manner as to coincide the center axis to the axial line of the lower shaft 2. Accordingly, the direct dissipation of heat of the bottom of the crucible 4 from the lower shaft 2 can be suppressed to enable the effective suppression of the heat-transfer from the molten raw material Y. Consequently, the temperature of the molten raw material can be maintained in uniform state to prevent the troubles such as the remarkable downward swelling of the interface or the contact of the crystal to the bottom of the container vessel to cause the bottom adhesion. Furthermore, since the temperature distribution at the bottom of the container vessel is uniformized, the generation of nuclei at the center of the lower part of molten raw material in the vessel can be prevented.
