Abstract:
Die Erfindung betrifft eine Prober zur Prüfung oder Testung mikroelektronischer Bauelemente (27), welcher eine Haltervorrichtung (26) für das Bauelements (27), zumindest eine Sonde (28) und ein vergrößerndes optisches Instrument (23, 23') umfasst. Um den Abstand zwischen dem zu beobachtenden mikroelektronischem Bauelement und dem optischen Instrument und damit den für die Sonden zur Verfügung stehenden Platz zu vergrößern, wird vorgeschlagen, ein Refraktionselement (3) zur Brechung der vom Bauelement in das optische Instrument verlaufenden Lichtstrahlen zumindest während der Kontaktierung und/oder Anregung des Bauelements im optischen Pfad des optischen Instruments zwischen dem Bauelement und dem optischen Instrument anzuordnen, wobei der Brechungsindex, die Form und Größe des Refraktionselementes (3) so gewählt sind, dass der Brennpunkt der durch das Refraktionselementes (3) verlaufenden Lichtstrahlen außerhalb des Refraktionselementes liegt.
Abstract:
Risers including a plurality of high aspect ratio electrical conduits, as well as systems and methods of manufacture and/or use of the risers and/or the high aspect ratio electrical conduits. The systems and methods may include incorporation of the plurality of high aspect ratio electrical conduits within a substantially planar- body that may include and/or be formed from a solid dielectric material. The plurality of electrical conduits may be configured to conduct a plurality of electric currents between a first surface of the body and a second, substantially opposed, surface of the body. The surfaces may include a plurality of contact pads configured to provide a robust and/or corrosion-resistant surface and/or to improve electrical contact between the riser and another device. The risers also may include a layered structure, wherein the layers are sequentially formed to increase a thickness of the riser and/or the aspect ratio of the electrical conduits.

Abstract:
In a membrane probing apparatus, the impedance of the interface between coaxial cables connected to the test instrumentation and the membrane supported co-planar waveguide that conductively connects to the probe's contacts is optimized by eliminating a ground plane in the interface board.
Abstract:
A wideband differential signal probe includes separate paths to respectively convert lower and higher frequency components of a differential signal to lower and higher frequency single ended signals that are combined for the probe's output.
