Abstract
The method includes preparing a plurality of light-emitting units, one of the plurality of light-emitting units comprising an electrode, a light-emitting stack, and a protection layer with a first part covering the electrode and a second part which comprises a portion surrounding the electrode and covers the light-emitting stack; removing the portion without removing the first part; forming a wavelength conversion layer on the first part and the light-emitting stack not covered by the second part; and removing the first part to substantially expose the electrode.
Claims16
A method of making a light-emitting diode, comprising:
- preparing a plurality of light-emitting units, one of the plurality of light-emitting units comprising an electrode, a light-emitting stack, and a protection layer having a first part covering the electrode and a second part which comprises a portion surrounding the electrode and covers the light-emitting stack;
- separating the plurality of light-emitting units into a plurality of light-emitting chips after the first part covering the electrode;
- removing the portion without removing the first part;
- forming a wavelength conversion layer on the first part and the light-emitting stack not covered by the second part;
- and
- removing the first part to substantially expose the electrode.
A method of making a light-emitting diode, comprising:
- preparing a plurality of light-emitting units which are connected to each other, one of the plurality of light-emitting units comprising an electrode, a light-emitting surface connected to the electrode, and a protection layer having a first part and a second part which covers the light-emitting surface;
- removing the second part to expose the light-emitting surface without removing the first part;
- forming a wavelength conversion layer on the first part and the light-emitting surface;
- and
- removing the first part to expose the electrode.
