    • An ingot diameter controlling apparatus and an ingot growing method are provided to produce the diameter of the ingot accurately by compensating the diameter or changing the sensing region of a sensor according to a melt gap. A sensor unit(610) senses the property of the meniscus which is the contact surface of a growing ingot(670) and a silicon solution(660) of a quartz furnace(650). A compensation unit produces a diameter compensation value to compensate the diameter of the ingot according to the change of the melt gap. A diameter producing unit(620) produces the diameter of the ingot through the compensation value of the diameter by the compensation unit and the property of the meniscus sensed by the sensor unit. A controller(640) controls the diameter of the ingot based on the diameter of the ingot produced through the diameter producing unit.

    • The present invention relates to a single crystalline silicon ingot by Czochralski method and, more particularly, to a single crystalline silicon ingot, a wafer and a method of producing a single crystalline silicon ingot in which an oxidation-induced stacking fault ring is distributed widely and which has an agglomerated vacancy point defect area of low density wherein DSOD exists only, without FPD. Accordingly, an oxidation-induced stacking fault area having a micro-vacancy defect area of low density is distributed widely from the ingot edge to the ingot center in a single crystalline silicon ingot and a wafer fabricated by the present invention. As the micro-vacancy defect area has no FPD but may have DSOD, a coarsely agglomerated vacancy point defect area in which FPD and DSOD cohabit is shrunken or even eliminated. Therefore, the present invention improves the product quality as well as device yield.
