Patent number: 10867873Abstract: A method and a device for measuring a plurality of semiconductor chips in a wafer array are disclosed. In an embodiment a method for measuring the semiconductor chips in a wafer array, wherein the wafer array is arranged on an electrically conductive carrier so that in each case back contacts of the semiconductor chips are contacted by the carrier, wherein a contact structure is arranged on a side of the wafer array facing away from the carrier, and wherein the contact structure includes a contact element and/or a plurality of radiation-emitting measurement semiconductor chips, includes applying a voltage between the contact structure and the carrier and measuring the semiconductor chips depending on a luminous image which is generated by emitted radiation which is caused simultaneously by fluorescence when the semiconductor chips are illuminated or by a radiation-emitting operation of the measurement semiconductor chips when the voltage is applied.Type: GrantFiled: July 25, 2017Date of Patent: December 15, 2020Assignee: OSRAM OLED GMBHInventors: Holger Specht, Roland Zeisel, Anton Vogl, Jens Ebbecke

Patent number: 9972748Abstract: A method for producing a thin-film semiconductor body is provided. A growth substrate is provided. A semiconductor layer with funnel-shaped and/or inverted pyramid-shaped recesses is epitaxially grown onto the growth substrate. The recesses are filled with a semiconductor material in such a way that pyramid-shaped outcoupling structures arise. A semiconductor layer sequence with an active layer is applied on the outcoupled structures. The active layer is suitable for generating electromagnetic radiation. A carrier is applied onto the semiconductor layer sequence. At least the semiconductor layer with the funnel-shaped and/or inverted pyramid-shaped recesses is detached, such that the pyramid-shaped outcoupling structures are configured as projections on a radiation exit face of the thin-film semiconductor.Type: GrantFiled: October 29, 2015Date of Patent: May 15, 2018Assignee: OSRAM OPTO SEMICONDUCTORS GMBHInventors: Christian Leirer, Anton Vogl, Andreas Biebersdorf, Rainer Butendeich, Christian Rumbolz
