METHOD FOR PRODUCING AND APPARATUS FOR PRODUCING SINGLE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for producing a single crystal having a cross sectional shape similiar to that of the desired wafer. SOLUTION: The apparatus 10 for producing the single crystal is the single crystal producing apparatus by Czochralski method. Reflecting plate 30 is partially disposed over the single crystal and in the peripheral direction of a single crystal pull up axis 22 and at the position where the heat radiation from the single crystal is inhibited to rotate synchronously with the single crystal.
