Abstract
A method for arraying micro-LED chips is disclosed. The method includes preparing a chip carrier formed with a plurality of chip pockets whose internal pressure is reduced through a plurality of suction holes, capturing the micro-LED chips in the corresponding chip pockets such that the micro-LED chips are in close contact with the bottoms of the chip pockets, and placing the micro-LED chips captured in the chip pockets on a base body. Each of the chip pockets includes a slope through which an inlet having a larger width than the bottom is connected to the bottom. The distances between the centers of the adjacent micro-LED chips placed on the base body are the same as those between the centers of the corresponding chip pockets.
