DEVICE AND METHOD FOR SELF-ASSEMBLING SEMICONDUCTOR LIGHT-EMITTING DIODES

Discussed is a device for self-assembling semiconductor light-emitting diodes, in which the device includes an assembly chamber having a space for accommodating a fluid; a magnetic field forming part having at least one magnet for applying a magnetic force to the semiconductor light-emitting diodes dispersed in the fluid and a moving part for changing positions of the at least one magnet so that the semiconductor light-emitting diodes move in the fluid; a substrate chuck having a substrate support part configured to support a substrate, and a vertical moving part for lowering the substrate so that one surface of the substrate is in contact with the fluid in a state in which the substrate is supported by the substrate support part; and a controller for controlling a movement of the magnetic field forming part and the substrate chuck, wherein the controller controls a depth at which the substrate is submerged in the fluid based on a degree of warping of the substrate.
