Abstract:
A single-crystal manufacturing apparatus including: at least two different melt surface position measuring means for measuring a melt surface position of a material melt; controlling means for controlling the melt surface position based on the measured melt surface position; and determining means for determining whether a measurement abnormality has occurred in the melt surface position measuring means, the apparatus being characterized in that the melt surface position is measured by the plurality of melt surface position measuring means at the same time, one melt surface position measuring means adopted for control over the melt surface position is selected from the plurality of melt surface position measuring means, and the melt surface position measuring means adopted for control over the melt surface position is switched to another melt surface position measuring means when the determining means determines that a measurement abnormality has occurred in the selected melt surface measuring means.

Claim (Index 1):
A single-crystal manufacturing apparatus which pulls a silicon single crystal from a material melt contained in a crucible by a Czochralski method, comprising:\n at least two different melt surface position measuring means for measuring a melt surface position of the material melt; controlling means for controlling the melt surface position based on the measured melt surface position; and determining means for determining whether a measurement abnormality has occurred in the melt surface position measuring means, wherein the melt surface position is measured by the plurality of melt surface position measuring means at the same time, one melt surface position measuring means adopted for control over the melt surface position is selected from the plurality of melt surface position measuring means, and the melt surface position measuring means adopted for control over the melt surface position is switched to another melt surface position measuring means when the determining means determines that a measurement abnormality has occurred in the selected melt surface measuring means.
