Abstract
PURPOSE: To obtain an extremely homogeneous Si single crystal of high quality by overlapping a pulling tube and a hot zone, comparing the measured value of the surface temp. of Si to a theoretically calculated internal temp. destribution of an Si single crystal, and controlling the temp. of the pulling tube so as to make the internal temp. distribution of the Si uniform.
CONSTITUTION: In order that the passing time of a grown Si single crystal in a hot zone especially of 900W600°C is made constant with respect to each range of the total length of the crystal, an overlap ΔX2 is provided to the relative position between the pulling tube 91 of a pulling apparatus and the hot zone forming body 92. The surface temp. of Si is measured at a renge just below an Si seed crystal or further measured at the inlet of the hot zone and other place, the measured value is compared to a theoretically calculated internal temp. distribution of the Si single crystal, and a single crystal is grown while controlling the temp. of the pulling tube so as to make the internal temp. distribution of the Si uniform.
