Abstract:
Provided are a micro LED and a method for manufacturing the same. When the micro LED is manufactured, an n-electrode and a protective layer formed on the micro LED is made of a variable resistance material that is a transparent material, and a voltage greater than a unique threshold voltage of the variable resistance material is applied to the variable resistance material on an area of the protective layer formed on the p-type semiconductor layer to form a conductive filament in the variable resistance material, thereby forming a transparent electrode. Thus, the micro LED according to the present invention may be produced with lower cost and higher productivity by omitting the mask process for forming the transparent electrode in the prior art.

Claim (Index 1):
A method for manufacturing a micro light emitting device (LED), the method comprising:\n a step (a) of successively forming a first semiconductor layer, an active layer, and a second semiconductor layer on a substrate; a step (b) of successively etching the second semiconductor layer, the active layer, and the first semiconductor layer by using a mask to expose the first semiconductor layer, thereby forming a plurality of micro LED cells on the substrate; a step (c) of forming first electrodes in parallel to each other in a plurality of rows between the micro LED cells by using a mask; a step (d) of depositing a variable resistance material that is a transparent material on the substrate to form a protective layer on the first electrodes and the second semiconductor layer of the plurality of micro LED cells and applying a voltage to each of protective layer regions formed above the second semiconductor layer to form a conductive filament, thereby forming a transparent electrode on the second semiconductor layer of the plurality of micro LED cells; and a step (e) of forming a second electrode on the transparent electrode of each of the micro LED cells by using a mask.
