Patent attributes
A heat shielding member 20 that thermally shields the periphery of a single crystal 16 used in a Czochralski single crystal pulling device that pulls the single crystal 16 from a melt 15 that is collected in a crucible 10 is disclosed. The heat shielding member 20 is provided with an approximately cylindrical main body portion 21 arranged so as to surround the single crystal 16, with a lower end portion thereof extending to the vicinity of the melt 15, and an approximately annular bottom plate portion 22 that extends in the diameter direction from the bottom end portion of the main body portion 21 to cover the melt. The bottom plate portion 22 is attached to the main body portion 21 in the state of being severed in the circumferential direction at at least one location. With this constitution it is possible to provide a heat shielding member with superior durability and a single crystal pulling device that employs the heat shielding member.
