Title:
SELF-ASSEMBLY APPARATUS AND METHOD FOR SEMICONDUCTOR LIGHT-EMITTING DEVICES
Document Type and Number:
WIPO Patent Application WO/2020/235732
Kind Code:
A1
Abstract:
A self-assembly apparatus and method of the present invention for semiconductor light-emitting devices can separate semiconductor light-emitting devices attached to each other by vibrating a fluid during self-assembly to thereby prevent mis-assembly and, for smooth assembly of the semiconductor light emitting devices, generate a flow of the fluid along the movement direction of a magnet. The self-assembly apparatus comprises: a chamber in which a plurality of semiconductor light-emitting devices comprising a magnetic substance and a fluid are accommodated; a transfer unit for transferring, to an assembly location, a substrate on which the semiconductor light-emitting devices are to be assembled; a magnet spaced apart from the chamber to apply a magnetic force to the semiconductor light-emitting devices; a location control unit for controlling a location of the magnet; and a vibration generation unit for generating vibration in the fluid to thereby separate the semiconductor light-emitting devices from each other.
