  • Patent number: 9528195
    Abstract: Provided is an apparatus for manufacturing a semiconductor or metal oxide ingot by sequentially inducing a liquid-to-solid phase transition of a liquid raw material following a solidification direction, the apparatus including: a crucible containing a semiconductor or metal oxide raw material; a cooling unit spaced apart from the crucible at a predetermined distance in a vertical direction, when a height direction of the crucible is designated by the vertical direction and a direction perpendicular to the vertical direction is designated by a horizontal direction; a first heating unit spaced apart from the crucible at a predetermined distance in the horizontal direction and surrounding a circumferential surface of the crucible; and an insulating member provided between the crucible and the cooling unit in the horizontal direction, a position of the insulating member being shifted by a shifting unit.
    Type: Grant
