Method for producing a conversion element, and conversion element
The invention relates to a method for producing a conversion element having the following steps: providing a frame having an opening; applying a sacrificial layer at least to a side surface of the at least one opening; applying a reflective layer to the sacrificial layer; introducing a conversion material into the at least one opening, the conversion material covering the reflective layer; and removing the sacrificial layer and the frame.
1. A method for producing a conversion element, comprising:
providing a frame having at least one opening,
applying a sacrificial layer at least to a side surface of the at least one opening,
applying a reflective layer to the sacrificial layer,
introducing a conversion material into the at least one opening, wherein the conversion material covers the reflective layer,
chemically etching the sacrificial layer to remove the sacrificial layer, and
removing the fame, wherein the reflective layer terminates flush with a bottom surface and a top surface of the conversion material.
2. The method as claimed in the preceding claim , wherein the side surface of the at least one opening has a chamfer.
3. A method for producing an optoelectronic semiconductor component, wherein
the method for producing the conversion element as claimed in claim 1 is carried out, and
before introducing the conversion material, a radiation-emitting semiconductor chip is introduced into the at least one opening.
4. The method as claimed in the preceding claim , wherein the conversion material introduced partly surrounds the radiation-emitting semiconductor chip.
5. A method for producing a conversion element, which is able to be applied on a radiation-emitting semiconductor chip, comprising:
providing a frame having at least one opening,
applying a sacrificial layer at least to a side surface of the at least one opening,
applying a reflective layer to the sacrificial layer,
introducing a conversion material into the at least one opening, wherein the conversion material covers the reflective layer,
chemically etching the sacrificial layer to remove the sacrificial layer, and
removing the frame.
6. The method of claim 5 , further comprising:
introducing the radiation-emitting semiconductor chip into the at least one opening.
