Patent ID: 11869871
Assignee: LG ELECTRONICS INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. 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 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.
