Method and apparatus for fabricating phosphor-coated LED dies

摘要

A lighting apparatus includes a first doped semiconductor layer, a light-emitting layer disposed over the first doped semiconductor layer, a second doped semiconductor layer disposed over the light-emitting layer, a first conductive terminal, a second conductive terminal, and a photo-conversion layer. The second doped semiconductor layer has a different type of conductivity than the first doped semiconductor layer. The first conductive terminal and the second conductive terminal each are disposed below the first doped semiconductor layer. The photo-conversion layer is disposed over the second doped semiconductor layer and on side surfaces of the first and second doped semiconductor layers and the light-emitting layer. A bottommost surface of the photo-conversion layer is located closer to the second doped semiconductor layer than bottom surfaces of the first and second conductive terminals.
