Abstract
A light-emitting diode (LED) and a method for manufacturing the same are described. The light-emitting diode has a first substrate. An illuminant epitaxial structure is deposited on a surface of the first substrate, in which the illuminant epitaxial structure has a first surface and a second surface opposite each other, the first surface is relatively adjacent to the first substrate, and the illuminant epitaxial structure includes at least one pit in the second surface. A second substrate is deposited on the second surface of the illuminant epitaxial structure. An adhesion layer is deposited between the second surface of the illuminant epitaxial structure and the second substrate to bond the second substrate to the illuminant epitaxial structure.
