Abstract: A semiconductor light emitter device for emitting light having a photon energy, comprises a mechanical carrier made substantially of a material that is an absorbant of the light with the photon energy, and having a carrier bottom side and a carrier top side opposite to the carrier bottom side, a layer structure epitaxially deposited on the carrier bottom side of the mechanical carrier and comprising an active-layer stack with at least two semiconductor layers of opposite conductivity types, which is configured to emit light upon application of a voltage to the active-layer stack, and at least one opening in the mechanical carrier, the opening reaching from the carrier bottom side to the carrier top side and being arranged and shaped to allow a passage of light, which is emitted from the active-layer stack, through the opening in the mechanical carrier.

Abstract: A method for testing devices produced in front end lots involving loading a plurality of front end lots into a tester without requiring the tester to complete tests on a previous front end lot. A secondary lot of devices is unloaded from the tester, the secondary lot containing devices from a plurality of front end lots. The plurality of front-end lots may form a batch. In this case, a plurality of secondary lots unloaded from the tester could correspond to the front-end lots, and could be considered to be part of the same batch. All secondary lots of the batch, except for the last secondary lot of the batch, may contain only pass devices, such that all fail devices from the batch are unloaded and then tested together, in the last secondary lot. The loading of the front-end lots may be asynchronous with the unloading of the secondary lots.

Abstract: A method for classifying semiconductor components by their performance characteristics includes reading an identifier associated with a component and storing, in conjunction with the identifier, first and second performances values for that component. These performance values represent the component's achieved operating speed at each of two different temperatures. The component is then allocated to a speed category on the basis of the first and second performance values.
