Abstract:
According to an aspect of an embodiment, provided is a micro semiconductor chip transferring substrate including: a mold including a plurality of recesses formed to be recessed in a certain depth from an upper surface; and a surface energy reduction pattern formed in region between the plurality of recesses, on the upper surface, the surface energy reduction pattern including a plurality of uneven patterns. When the micro semiconductor chips are aligned by a wet alignment method, by such surface energy reduction pattern, sliding of the micro semiconductor chips toward the inside of the recesses may be improved.
