Raw material supply unit, and apparatus comprising same for growing single-crystal silicon ingot

A raw material supply unit comprising:

• a body having a space configured to be filled with a raw material;
• a partition configured to divide the body in a longitudinal direction to form at least two regions within an inner region of the body, a first one of the at least two regions formed on a first side of the partition and a second one of the at least two regions formed on a second side of the partition;
• a rod extending from above the body to the inner region of the body so as to be disposed in the body;
• and
• a valve connected to the rod, the valve being configured to open and close a lower part of the body,
• wherein the lower part of the body forms an open area that includes at least a first open area and a second open area,
• wherein a lower surface of the body, which is different than a lower surface of the valve, comprises a first portion having a first height and a second portion having a second height greater than the first height, the first portion is part of a circumference of the first open area, the second portion is part of a circumference of the second open area, and the first open area is defined as part of the open area adjacent to the first portion, and the second open area is defined as part of the open area adjacent to the second portion,
• wherein a difference between the first height and the second height is 30 mm to 70 mm,
• wherein a border between the first portion and the second portion is to extend to vertically overlap with the partition,
• wherein the valve has a conical shape,
• the conical shape comprises a first inclined surface and a second inclined surface, and
• wherein the valve is configured to move up and down within the open area of the body,
• the first inclined surface of the valve overlaps the first open area in a vertical direction, and the second inclined surface of the valve overlaps the second open area in the vertical direction.
