Abstract
A single-crystal ingot growing method includes setting a location of an MGP (maximum gauss position) of a magnetic field such that the MGP is located above the surface of a melt, setting a difference in intensity of the magnetic field between a center point of the melt and an edge point of the melt based on the set location of the MGP, setting an intensity of the magnetic field that is applied to the melt based on the set difference in intensity of the magnetic field, and growing a single-crystal ingot based on the set location of the MGP and the set intensity of the magnetic field. The magnetic field is a horizontal magnetic field, the MGP is spaced apart from the surface of the melt by a distance ranging from +50 mm to +150 mm, and the difference in intensity of the magnetic field ranges from 420G to 500G.
