摘要:
The present disclosure involves a method of packaging a light-emitting diode (LED). According to the method, a group of metal pads and a group of LEDs are provided. The group of LEDs is attached to the group of metal pads, for example through a bonding process. After the LEDs are attached to the metal pads, each LED is spaced apart from adjacent LEDs. Also according to the method, a phosphor film is coated around the group of LEDs collectively. The phosphor film is coated on top and side surfaces of each LED and between adjacent LEDs. A dicing process is then performed to slice through portions of the phosphor film located between adjacent LEDs. The dicing process divides the group of LEDs into a plurality of individual phosphor-coated LEDs.
