METHOD AND APPARATUS FOR FABRICATING PHOSPHOR-COATED LED DIES |
摘要 |
The present disclosure involves lighting apparatus. The lighting apparatus includes a first doped semiconductor layer. A light-emitting layer is disposed over the first doped semiconductor layer. A second doped semiconductor layer is disposed over the light-emitting layer. The second doped semiconductor layer has a different type of conductivity than the first doped semiconductor layer. A first conductive terminal and a second conductive terminal are each disposed below the first doped semiconductor layer. A 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. |
