摘要： Provided are an apparatus and method for supplying a light-emitting diode (LED) wafer that may quickly and accurately transfer LED wafers by acquiring position information of pockets in a carrier in which the LED wafers are to be seated. The apparatus may include a cassette in which a plurality of LED wafers are loaded, a carrier including a plurality of pockets in which the LED wafers are seated, an aligning unit to align the LED wafers that are to be seated in the carrier, a transfer robot to transfer the LED wafers from the cassette to the aligning unit, a picker to hold, in an adsorbed state, the LED wafers transferred to the aligning unit, or to release the adsorbed state, a capturing unit to fix the picker, and to acquire position information of the pockets, and an LED wafer loading robot to transfer the picker and the capturing unit from the aligning unit to the carrier. Accordingly, the LED wafers may be quickly and accurately loaded in the carrier and thus, it is possible to reduce a total process time and to significantly lower a defect rate.
