    摘要: The present invention relates to an apparatus for manufacturing a high-quality semiconductor single crystal ingot and a method using the same. The apparatus of the present invention includes a quartz crucible (10), a heater (40) installed around a side wall of the quartz crucible (10), a single crystal pulling means (60) for pulling a single crystal from the semiconductor melt (M) received in the quartz crucible (10), and a magnetic field applying means (80) for forming a Maximum Gauss Plane (MGP) at a location of ML-100 mm to ML-350 mm based on a Melt Level (ML) of the melt surface, and applying a strong magnetic field of 3000 to 5500 Gauss to an intersection between the MGP and the side wall of the quartz crucible and a weak magnetic field of 1500 to 3000 Gauss below a solid-liquid interface.
