Abstract:
An apparatus for aligning microelements on a substrate and a method for the same are provided. The steps of the method include providing a substrate, forming a protruding structure on the substrate, providing a microelement, forming a microdroplet on the protruding structure, and forcing the microelement to contact the microdroplet. The surface tension of the microdroplet is used to move the microdroplet to a surface of the protruding structure.
