Method for producing a conversion lamina and conversion lamina

1. A method for producing at least one conversion lamina for a radiation-emitting semiconductor component, the method comprising:

applying a base material comprising a conversion substance contained therein onto a substrate using a double-layer template,

wherein the base material contains silicone;

wherein the substrate is a film substrate which is arranged on a clamping device,

wherein the template comprises two regions, which are arranged vertically above one another, a shaping region facing toward the substrate replicating a shape of the conversion lamina to be produced and a region facing away from the substrate having a grid structure for stabilization of the template;

wherein each grid structure is composed of a plurality of openings arranged as a grid, each opening of the grid structure having a smaller lateral extent than the shaping region, so that a plurality of the openings, arranged in the manner of a matrix, of the grid structure are arranged over each shaping region;

wherein the template consists substantially of nickel; and

wherein the shaping region is formed such that a produced conversion lamina has a recess arranged in an intended bonding pad region of a radiation-emitting semiconductor component.

2. The method according to claim 1 , wherein the base material comprising conversion substance contained therein is applied by a printing method.

3. The method according to claim 1 , wherein the template comprises at least one opening, through which the base material comprising the conversion substance contained therein is pressed onto the substrate.

4. The method according to claim 3 , wherein the template comprises a printing side and a bearing side.

5. The method according to claim 4 , wherein the base material comprising the conversion substance contained therein is applied onto the printing side and subsequently pressed onto the substrate through the template with a squeegee.

6. The method according to claim 1 , wherein the template is arranged in direct contact with the substrate when the base material is being applied.

7. The method according to claim 1 , wherein the conversion lamina is produced with a thickness of between 60 μm inclusive and 170 μm inclusive.

8. The method according to claim 1 , wherein a plurality of conversion laminae are produced in a combined method, these laminae being applied onto the substrate in a combined method step by a printing method.

9. The method according to claim 8 , wherein the template comprises a plurality of openings, by which the shape of a conversion lamina is respectively determined.

10. The method according to claim 1 , wherein the substrate and the conversion lamina are free from a radiation-emitting semiconductor component.

11. A method for producing at least one conversion lamina for a radiation-emitting semiconductor component, the method comprising:

applying a base material comprising a conversion substance contained therein onto a substrate using a double-layer template;

wherein the template comprises two regions, which are arranged vertically above one another, a shaping region facing toward the substrate replicating a shape of the conversion lamina to be produced and a region facing away from the substrate having a grid structure for stabilization of the template;

wherein each grid structure is composed of a plurality of openings arranged as a grid, each opening of the grid structure having a smaller lateral extent than the shaping region, so that a plurality of the openings, arranged in the manner of a matrix, of the grid structure are arranged over each shaping region; and

wherein the shaping region is formed such that a produced conversion lamina has a recess arranged in an intended bonding pad region of a radiation-emitting semiconductor component.

12. The method according to claim 11 , wherein the template consists of only one material.

13. The method according to claim 12 , wherein the template consists of nickel.
