Zusammenfassung: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.
