Abstract: An apparatus and method capable of efficiently manufacturing a LED module. The method of manufacturing an Light Emitting Diode (LED) module includes preparing a substrate and a carrier on which an LED chip is disposed, disposing a mask on the substrate, the mask including an opening and a wall defining or forming the opening, picking up the LED chip from the carrier with a stamp, moving the LED chip picked up by the stamp to face the opening, moving the LED chip so that at least a part of the LED chip is inserted into the opening, and positioning the LED chip on the substrate by moving the LED chip so that the at least a part of the LED chip contacts the wall.
