Abstract
(A1) Die Erfindung betrifft einen Tastkopf, enthaltend zumindest einen ersten Anschluss mit einer ersten Impedanz und zumindest einen zweiten Anschluss mit einer zweiten Impedanz und einer Einrichtung zur Impedanzanpassung, welche die erste Impedanz in die zweite Impedanz ueberfuehrt, wobei der Tastkopf zumindest einen dritten Anschluss enthaelt, ueber welchen elektrische Energie zufuehrbar ist, und die Einrichtung zur Impedanzanpassung zumindest ein aktives Halbleiterbauelement enthaelt. Weiterhin betrifft die Erfindung ein Verfahren zum Betrieb eines Halbleiterbauelementes unter Verwendung eines solchen Tastkopfes.
WO 2011006855 A1 UPAB: 20110207 NOVELTY - The probe (1) has two connections (21, 23) with different impedances, and an impedance adaptation device (11). The impedance adaptation device converts the impedance in one of the connections (21) into the other impedance. A third connection (20) supplies electric energy to the probe. The impedance adaptation device is provided with an active semiconductor component (12). Electrical energy is made available at the second connection for supplying a semiconductor component to be checked e.g. photodiode, with supply voltage and/or supply current. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating a semiconductor component. USE - Probe for use in a semiconductor component e.g. optical modulator, semiconductor laser and photodiode (all claimed), during checking. Can also be used in an amplifier circuit and a dynamic RAM during checking. ADVANTAGE - The electrical energy is made available at the second connection for supplying the semiconductor component to be checked e.g. photodiode, with the supply voltage and/or the supply current, so that the frequency range is improved and the reflections on the meter is reduced. The design of the probe allows transmission of increased electric power to the semiconductor component.
