Abstract:
A single-crystal pulling apparatus including a pulling furnace containing a crucible containing molten single crystal material, and a magnetic field generation device that is arranged around the furnace, has superconducting coils, and generates a magnetic field distribution. A magnetic flux density distribution on an X axis, which is a direction of magnetic force lines at the central axis in a horizontal plane, is a convex upward distribution, and a magnetic flux density on the X axis becomes 80% or less of a magnetic flux density set value at a crucible wall. Simultaneously, a magnetic flux density distribution on a Y axis, orthogonal to the X axis, is a convex downward distribution, and a magnetic flux density on the Y axis becomes 140% or more of the set value at the crucible wall when the magnetic flux density at the central axis in the horizontal plane is the set value.

Claim (Index 7):
A single-crystal pulling method comprising pulling a semiconductor single crystal by using the single-crystal pulling apparatus according to  claim 5 .
