Abstract: 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.

A phosphor layer is coated over the plurality of LEDs. The phosphor layer is then cured. The tape and the substrate are removed after the curing of the phosphor layer. A replacement tape is then attached to the plurality of LEDs. A dicing process is then performed to the plurality of LEDs after the substrate has been removed. The removed substrate may then be reused for a future LED packaging process.
