Title:
SELF-ASSEMBLY APPARATUS AND METHOD FOR SEMICONDUCTOR LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/091252
Kind Code:
A1
Abstract:
The present invention provides a self-assembly apparatus for a semiconductor light emitting device comprising: a fluid chamber having a space for accommodating a plurality of semiconductor light emitting devices; a transfer unit for transferring a substrate to an assembly location; a magnet arranged to be separated from the fluid chamber so as to apply magnetic force to the semiconductor light emitting devices; a location control unit which is connected to the magnet and which is formed to control the location of the magnet; and a power supply unit which induces the substrate to form an electric field so that the semiconductor light emitting devices are loaded at predetermined locations of the substrate when moving according to a location change of the magnet, wherein the location control unit transfers the rotational shaft in one direction while rotating the magnet around a rotational shaft.
