15. A semiconductor structure, comprising:
a semiconductor pickup element having at least one guiding structure and provided with a pickup portion; and
an epitaxial structure adapted to the semiconductor pickup element, wherein the epitaxial structure comprises:
a semiconductor layer corresponding to the pickup portion and capable of being picked up by the semiconductor pickup element; and
at least one alignment structure disposed on the semiconductor layer and corresponding to the at least one guiding structure, so that the epitaxial structure and the semiconductor pickup element are positioned relative to each other, wherein the number of the at least one alignment structure matches the number of the at least one guiding structure.
