Vacuum tray and method of manufacturing light emitting device using the same

1. A vacuum tray, comprising:

a pocket part;

a seating part stepped downwardly from a bottom surface of the pocket part and having a light emitting device seated therein;

a cavity part stepped downwardly from edges of the seating part and having an electrode terminal of the light emitting device accommodated therein; and

a vacuum hole provided in a bottom surface of the cavity part and communicating with the cavity part.

2. The vacuum tray of claim 1 , wherein the pocket part comprises a plurality of pocket parts having a matrix structure such that the plurality of pocket parts are arranged in columns and rows.

3. The vacuum tray of claim 1 , wherein the pocket part has internal side surfaces inclined toward the light emitting device such that an area defined by upper edges of the pocket part is wider than that of the bottom surface of the pocket part.

4. The vacuum tray of claim 1 , wherein the pocket part has an upper edge disposed to be higher than an upper surface of the light emitting device.

5. A vacuum tray, comprising:

a pocket part:

a seating part stepped downwardly from a bottom surface of the pocket part and having a light emitting device seated therein; and

a cavity part stepped downwardly from edges of the seating part and having an electrode terminal of the light emitting device accommodated therein, wherein:

the seating part includes a vertical surface contacting a side surface of the light emitting device and a flat surface extending from the vertical surface in a horizontal manner and contacting a lower surface of the light emitting device, and

the seating part has a shape corresponding to that of the light emitting device.

6. The vacuum tray of claim 5 , wherein the seating part further includes a sealing member provided on the flat surface.

7. The vacuum tray of claim 2 , wherein intervals between upper edges of the pocket parts and seating parts provided within the corresponding pocket parts are consistent.

8. The vacuum tray of claim 1 , wherein the pocket part includes at least one seating part and at least one cavity part therein.

9. A method of manufacturing a light emitting device, the method comprising:

preparing a vacuum tray including a pocket part, a seating part stepped downwardly from a bottom surface of the pocket part and having a light emitting device seated therein, and a cavity part stepped downwardly from edges of the seating part and having an electrode terminal of the light emitting device accommodated therein;

mounting the light emitting device in the seating part within the pocket part such that the electrode terminal formed on a lower surface of the light emitting device is accommodated in the cavity part;

forming a phosphor layer by filling the pocket part with a resin containing a phosphor material while covering the light emitting device; and

separating the light emitting device having the phosphor layer formed thereon from the pocket part of the vacuum tray.

10. The method of claim 9 , wherein the pocket part comprises a plurality of pocket parts having a matrix structure such that the plurality of pocket parts are arranged in columns and rows.

11. The method of claim 9 , wherein the mounting of the light emitting device includes fixing the light emitting device to the seating part using a vacuum hole communicating the cavity part.

12. The method of claim 9 , wherein the forming of the phosphor layer includes:

providing the resin to the pocket part to be even with an upper surface of the vacuum tray to thereby obtain planarization; and

hardening the resin.

13. The method of claim 12 , wherein the planarization is performed by removing an excess amount of the resin protruded upwardly from the upper surface of the vacuum tray from the pocket part using a squeegee.

14. The method of claim 12 , further comprising polishing an upper surface of the phosphor layer being hardened.
