Abstract
Discussed is an apparatus for self-assembling semiconductor light-emitting devices, the apparatus including a fluid chamber to accommodate the semiconductor light-emitting devices, each semiconductor light-emitting device having a magnetic body; a magnet to apply a magnetic force to the semiconductor light-emitting devices while an assembly substrate is disposed at an assembly position of the self-assembly apparatus; a power supply to induce formation of an electric field on the assembly substrate to allow the semiconductor light-emitting devices to be seated at a preset positions on the assembly substrate in a process of moving the semiconductor light-emitting devices due to a change in a position of the magnet; and a fluid injector to shoot a fluid to some of the semiconductor light-emitting devices to allow the some of the semiconductor light-emitting devices seated on the assembly substrate to be separated from the assembly substrate.
