Abstract: Systems and methods for simultaneous optical testing of a plurality of devices under test. These systems and methods may include the use of an optical probe assembly that includes a power supply structure that is configured to provide an electric current to a plurality of devices under test (DUTs) and an optical collection structure that is configured to simultaneously collect electromagnetic radiation that may be produced by the plurality of DUTs and to provide the collected electromagnetic radiation to one or more optical detection devices. The systems and methods also may include the use of the optical probe assembly in an optical probe system to evaluate one or more performance parameters of each of the plurality of DUTs.

Abstract: The invention relates to a prober for checking and testing electronic semiconductor components and methods of using the same. The prober comprises at least two checking units, each of which is equipped with a chuck, probes, and a positioning unit, and each of which is assigned to a machine control system and a process control system. The prober further comprises a loading unit for automatically loading both testing units and an additional loader for manually loading at least one of the testing units, a user interface, and a module control system for controlling the process control systems and/or the machine control systems and the loading unit. The user interface can optionally be connected to at least one of the process control systems or the module control system by means of a switching device of the prober.
