Abstract
A light-emitting device includes a first epi-structure with a top surface and a bottom surface opposite to the top surface, a first metal element and a second metal element disposed on the bottom surface, a first through-via, a conductive element disposed on the top surface, and a phosphor layer disposed on the top surface and covering the conductive element. The first epi-structure includes a first doped semiconductor layer, a second doped semiconductor layer closer to the bottom surface than the first doped semiconductor layer, and a light-emitting layer disposed between the first and second doped semiconductor layers. The first through-via extends through the first doped semiconductor layer and the second doped semiconductor layer and is electrically connected to the first doped semiconductor layer and the second metal element. The conductive element is in a configuration to expose a portion of the top surface, and electrically connected to the first through-via.
