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

Claim 14:
15. A self-assembly apparatus, comprising:
a fluid chamber configured to accommodate a plurality of semiconductor light-emitting devices immersed in a fluid;
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 an electric field on the assembly substrate so that the plurality of semiconductor light-emitting devices are seated at a preset positions on the assembly substrate when the magnet is used to move the plurality of semiconductor light-emitting devices; and
a fluid injector configured to shoot the fluid to some of the plurality of semiconductor light-emitting devices to dislodge the some of the plurality of semiconductor light-emitting devices seated on the assembly substrate from the assembly substrate,
wherein the fluid injector comprises at least one hole oriented upwards in a direction opposite to gravity caused by a gravitational force of the earth and used to shoot the fluid upwards towards the some of the plurality of semiconductor light-emitting devices.
