Abstract:
Disclosed are a transfer carrier and a manufacturing method thereof, and a method for transferring a light-emitting diode chip. The transfer carrier includes: a substrate having a plurality of via holes penetrating a thickness of the substrate, the substrate having a first surface and second surface which are opposite to each other; and thermoplastic structures filling corresponding ones of the via holes, one end of the thermoplastic structures protruding from the second surface of the substrate, and the other end covering a surrounding area on the first surface, of the corresponding via holes.
