An optoelectronic semiconductor body () having an active semiconductor layer sequence () and a reflective layer system () is described. The reflective layer system () comprises a first radiation-permeable layer (), which adjoins the semiconductor layer sequence (), and a metal layer () on the side of the first radiation-permeable layer () facing away from the semiconductor layer sequence (). The first radiation-permeable layer () contains a first dielectric material. Between the first radiation-permeable layer () and the metal layer () there is disposed a second radiation-permeable layer () which contains an adhesion-improving material. The metal layer () is applied directly to the adhesion-improving material. The adhesion-improving material differs from the first dielectric material and is selected such that the adhesion of the metal layer () is improved in comparison with the adhesion on the first dielectric material.

Optoelectronic semiconductor bodies having a reflective layer system

A light emitting diode includes a semiconductor body including an active region that produces radiation, a carrier body fastened to the semiconductor body on an upper side of the semiconductor body, the carrier body including a luminescence conversion material consisting of a ceramic luminescence conversion material, a mirror layer applied to the semiconductor body on an underside of the semiconductor body remote from the upper side, and two contact layers, a first contact layer of the contact layers connected electrically conductively to an n-conducting region of the semiconductor body and a second contact layer of the contact layers connected electrically conductively to a p-conducting region of the semiconductor body.

Light-emitting diode comprising a carrier body, a mirror layer, and two contact layers

An optoelectronic semiconductor chip includes a semiconductor body containing an active region, a mirror layer, and contact points arranged between the semiconductor body and the mirror layer and providing a spacing D between the semiconductor body and the mirror layer, whereby at least one cavity is formed between the mirror layer and the semiconductor body and the at least one cavity contains a gas.

Optoelectronic semiconductor chip with gas-filled mirror

An optoelectronic semiconductor chip includes a semiconductor layer sequence having at least one doped functional layer having at least one dopant and at least one codopant, wherein the semiconductor layer sequence includes a semiconductor material having a lattice structure, one selected from the dopant and the codopant is an electron acceptor and the other an electron donor, the codopant is bonded to the semiconductor material and/or arranged at interstitial sites, and the codopant at least partly forms no bonding complexes with the dopant.

A semiconductor body includes an n-conductive semiconductor layer and a p-conductive semiconductor layer. The p-conductive semiconductor layer contains a p-dopant and the n-conductive semiconductor layer an n-dopant and a further dopant.

Semiconductor body and method of producing a semiconductor body

On an epitaxy substrate (), a layer structure () provided for light-emitting diodes or other optoelectronic components using thin-film technology is produced and provided with a first connecting layer (), which comprises one or a plurality of solder materials. A second connecting layer () is applied over the whole area on a carrier () and permanently connected to the first connecting layer () by means of a soldering process.

Method for the production of an optoelectronic component using thin-film technology

A method for bonding several layers, which comprise at least one thermally bondable material, by means of a joint layer produced with the aid of thermocompression at least one of the layers comprising a semiconductor material, as well as to a correspondingly manufactured device. Also disclosed is a method for manufacturing an organic light-emitting diode and an organic light-emitting diode that is encapsulated between two cover layers with the aid of thermocompression.

Method for bonding layers, corresponding device and organic light-emitting diode

A semiconductor chip (), to which a layer sequence () intended for the production of a soldered connection has been applied. The layer sequence () comprises a solder layer () and an oxidation prevention layer (), which follows the solder layer () as seen from the semiconductor chip (). A barrier layer () is included between the solder layer () and the oxidation prevention layer (). This prevents a constituent of the solder layer () from diffusing through the oxidation prevention layer () prior to the soldering operation, where it would effect oxidation that is disadvantageous for producing a soldered connection.
