Assignee: LG ELECTRONICS INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A self-assembly apparatus, comprising:
a fluid chamber configured to accommodate a plurality of semiconductor light-emitting devices, each semiconductor light-emitting device having a magnetic body;
a magnet configured to apply a magnetic force to the plurality of semiconductor light-emitting devices while an assembly substrate is disposed at an assembly position of the self-assembly apparatus;
a power supply configured to induce formation of an electric field on the assembly substrate to allow the plurality of semiconductor light-emitting devices to be seated at a preset positions on the assembly substrate in a process of moving the plurality of semiconductor light-emitting devices due to a change in a position of the magnet; and
a fluid injector configured to shoot a fluid to some of the plurality of semiconductor light-emitting devices to allow the some of the plurality of semiconductor light-emitting devices seated on the assembly substrate to be separated from the assembly substrate,
wherein the assembly substrate is disposed in the fluid chamber to allow an assembly surface on which the plurality of semiconductor light-emitting devices are assembled to face downward, and
wherein a light-transmitting bottom plate is disposed in the fluid chamber, and the plurality of semiconductor light-emitting devices are disposed between the light-transmitting bottom plate and the assembly substrate.
