Abstract

Disclosed is a method of making an optoelectronic device that incorporates a crosslinked resin-linear polyorganosiloxane.

Claims (23)

1. A method of manufacturing an optoelectronic device comprising:

i) providing a substrate wherein the substrate comprises one or more electro-optic component arranged on at least one surface of the substrate;

ii) contacting the surface of the electro-optic component parallel to the substrate with a lateral filler film comprising a filler and a curable silicone hot melt;

iii) contacting the lateral filler film with a release liner; and

iv) applying pressure to the lateral filler film, and

v) removing a residue that is formed on the top surface of the electro-optic component, to create the optoelectronic device.

2. The method of claim 1 wherein the electro-optic component is a light emitting diode.

3. The method of claim 1 wherein the curable silicone hot melt is a crosslinkable resin-linear polyorganosiloxane formulation.

4. The method of claim 1 wherein the lateral filler film is uncured prior to applying pressure.

5. The method of claim 1 wherein the filler comprises a compound selected from the group consisting of TiO 2 , BN, SiO 2 , Al 2 O 3 , ZnO, BaSO 4 , and mixtures thereof.

6. The method of claim 1 wherein the residue is removed by wiping with a solvent.

7. The method of claim 1 wherein the solvent comprises isopropyl alcohol, acetone, heptane, octane, propylpropionate, toluene, and mixtures thereof.

8. An optoelectronic device manufactured by the method of claim 1 .

9. The method of claim 1 wherein the electro-optic component is an LED chip, and wherein after pressure is applied, a residue is formed on the top surface of the LED chip and is further removed.

10. The method of claim 1 wherein the thickness of the lateral filler film is arranged to the same or less as the height of the electro-optic component from the surface of the substrate prior to contacting it to the surface of the electro-optic component.

11. A method of manufacturing an optoelectronic device comprising:

i) providing a substrate wherein the substrate comprises one or more electro-optic component arranged on at least one surface of the substrate,

ii) contacting the surface of the electro-optic component parallel to the substrate with a lateral filler film comprising a filler and a curable silicone hot melt;

iii) contacting the lateral filler film with a release liner;

iv) applying pressure to create the optoelectronic device;

v) applying a wavelength conversion layer on top of the created optoelectronic device; and

vi) curing simultaneously.

12. An optoelectronic device manufactured by the method of claim 11 .
