Optoelectronic semiconductor component
View Patent ↗An optoelectronic semiconductor component includes a carrier which has an upper side and a lower side opposite to the upper side. At least one radiation-emitting semiconductor device is disposed on the upper side and has a radiation emission surface, through which at least a portion of the electromagnetic radiation, which is generated during operation of the semiconductor device, leaves the semiconductor device. A radiation-absorbing layer is arranged to absorb ambient light, which impinges upon the component, such that an outer surface of the component facing away from the carrier appears black at least in places.
1. Optoelectronic semiconductor component, comprising:
a carrier having an upper side and a lower side opposite to the upper side;
at least one radiation-emitting semiconductor device which is disposed on the upper side and has a radiation emission surface, through which at least a portion of the electromagnetic radiation, which is generated during operation of the radiation emitting semiconductor device, leaves the radiation-emitting semiconductor device;
a radiation-absorbing layer which is arranged to absorb ambient light, which impinges upon the optoelectronic semiconductor component, such that an outer surface of the optoelectronic semiconductor component facing away from the carrier appears black at least in places; and
a radiation-reflecting layer which covers the lateral surfaces of the semiconductor device in places and which is disposed in a vertical direction between the carrier and the radiation-absorbing layer,
wherein the radiation-absorbing layer completely encircles the radiation-emitting semiconductor device in a lateral direction and is in direct contact, at least in places, with lateral surfaces of the radiation-emitting semiconductor device,
wherein the outer surface of the semiconductor component is formed at least in places by an outer surface of the radiation-absorbing layer, and
wherein the radiation emission surface is free from the radiation-absorbing layer.
2. The optoelectronic semiconductor component as claimed in claim 1 , wherein the radiation-absorbing layer comprises a filler which, at least in places, encases the lateral surfaces of the radiation-emitting semiconductor device in a positive-locking manner.
3. The optoelectronic semiconductor component as claimed in claim 1 , wherein the radiation-absorbing layer does not protrude beyond the radiation-emitting semiconductor device in a vertical direction.
4. The optoelectronic semiconductor component as claimed in claim 1 , wherein a bond wire contacting the at least one radiation-emitting semiconductor device is covered at least partially by the radiation-absorbing layer.
