Abstract
An epitaxial structure adapted to a semiconductor pickup element is provided. The semiconductor pickup element has at least one guiding structure and provided with a pickup portion. The epitaxial structure includes a semiconductor layer corresponding to the pickup portion and capable of being picked up by the semiconductor pickup element. The epitaxial structure also includes 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. The number of the at least one alignment structure matches the number of the at least one guiding structure.
