Abstract

A method of manufacturing a light-emitting device that includes providing a plurality of element structures, each of which includes a submount substrate, a light-emitting element, and a light-transmissive member in this order. The method further includes disposing the plurality of element structures such that the light-transmissive members face a sheet member, and forming a covering member on the sheet member to cover at least a portion of each of lateral surfaces of the submount substrate of each of the element structures.

Claims (41)

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

providing a plurality of element structures, each of which includes a submount substrate, a light-emitting element, and a light-transmissive member in this order;

disposing the plurality of element structures such that the light-transmissive members face a sheet member; and

forming a covering member on the sheet member to cover at least a portion of each of lateral surfaces of the submount substrate of each of the element structures,

the method further comprising, before the forming of the covering member on the sheet member:

forming a frame on the sheet member to surround the plurality of element structures; and

disposing the covering member in the frame such that the covering member covers at least a portion of each of the lateral surfaces of the submount substrate of each element structure.

2. The method of manufacturing a light-emitting device according to claim 1 ,

wherein the frame has an elongated-rectangular shape in a plan view, and

wherein one long side or two long sides of the elongated-rectangular shape include metals, alloys, or ceramics.

3. The method of manufacturing a light-emitting device according to claim 2 , wherein the providing of the plurality of element structures comprises:

providing a collective substrate that includes a plurality of submount regions each of which constitutes the submount substrate after the collective substrate is divided;

disposing the light-emitting elements on the submount regions;

disposing the light-transmissive members on respective light-emitting elements; and

dividing the collective substrate for respective submount regions into the plurality of element structures.

4. The method of manufacturing a light-emitting device according to claim 2 , further comprising removing the sheet member.

5. The method of manufacturing a light-emitting device according to claim 2 , wherein the covering member is a light-reflective resin.

6. A method of manufacturing a light-emitting module, the method comprising:

providing a light-emitting device using the method of manufacturing the light-emitting device according to claim 2 ; and

disposing the light-emitting device such that the submount substrates face a module substrate.

7. The method of manufacturing a light-emitting device according to claim 1 , wherein the frame is made of metals, alloys, or ceramics.

8. The method of manufacturing a light-emitting device according to claim 7 , wherein the providing of the plurality of element structures comprises:

providing a collective substrate that includes a plurality of submount regions each of which constitutes the submount substrate after the collective substrate is divided;

disposing the light-emitting elements on the submount regions;

disposing the light-transmissive members on respective light-emitting elements; and

dividing the collective substrate for respective submount regions into the plurality of element structures.

9. The method of manufacturing a light-emitting device according to claim 7 , further comprising removing the sheet member.

10. The method of manufacturing a light-emitting device according to claim 7 , wherein the covering member is a light-reflective resin.

11. A method of manufacturing a light-emitting module, the method comprising:

providing a light-emitting device using the method of manufacturing the light-emitting device according to claim 7 ; and

disposing the light-emitting device such that the submount substrates face a module substrate.

12. The method of manufacturing a light-emitting device according to claim 1 , wherein the providing of the plurality of element structures comprises:

providing a collective substrate that includes a plurality of submount regions each of which constitutes the submount substrate after the collective substrate is divided;

disposing the light-emitting elements on the submount regions;

disposing the light-transmissive members on respective light-emitting elements; and

dividing the collective substrate for respective submount regions into the plurality of element structures.

13. The method of manufacturing a light-emitting device according to claim 1 , further comprising removing the sheet member.

14. The method of manufacturing a light-emitting device according to claim 1 , wherein the covering member is a light-reflective resin.

15. A method of manufacturing a light-emitting module, the method comprising:

providing a light-emitting device using the method of manufacturing the light-emitting device according to claim 1 ; and

disposing the light-emitting device such that the submount substrates face a module substrate.
