Abstract:
A wet alignment method for a micro-semiconductor chip and a display transfer structure are provided. The wet alignment method for a micro-semiconductor chip includes: supplying a liquid to a transfer substrate including a plurality of grooves; supplying the micro-semiconductor chip onto the transfer substrate; scanning the transfer substrate by using an absorber capable of absorbing the liquid. According to the wet alignment method, the micro-semiconductor chip may be transferred onto a large area.
