    • A system for low-current testing of a test device includes a probing device for probing a probing site on the test device. The probing device includes a dielectric substrate having first and second sides, an elongate conductive path on the first side of the substrate, an elongate probing element connected to one end of the elongate conductive path so as to extend in a cantilevered manner beyond the substrate, and a conductive area on the second side of the substrate. The probe housing is matingly detachably engageable with the probing device. The probe housing is engaged with both a force cable that includes a force conductor surrounded by a guard conductor and a sense cable that includes a sense conductor surrounded by a guard conductor. A first coupler electrically interconnects the force conductor, the sense conductor, and the elongate conductive path on the first side of the substrate when the probing device is engaged with the probe housing. A second coupler electrically interconnects the guard conductor of the force and sense cables and the conductive area on the second side of the substrate when the probing device is engaged with the probe housing.

    • A low-current probe card for measuring currents down to the femtoamp region includes a dielectric board, such as of glass-epoxy material, forming an opening. A plurality of probing devices, such as ceramic blades, are edge-mounted about the opening so that the probing elements or needles included thereon terminate below the opening in a pattern suitable for probing a test device. A plurality of cables are attached to the card for respectively connecting each device to a corresponding channel of a test instrument. The on-board portion of each cable is of coaxial type and includes an inner layer between the inner dielectric and outer conductor for suppressing the triboelectric effect. An inner conductive area and a conductive backplane that are respectively located below and on one side of each device are set to guard potential via the outer conductor of the corresponding cable so as to guard the signal path on the other side of the device. The lead-in portion of each cable, which is detachably connected to the corresponding on-board portion through a plug-in type connector, is of triaxial type and includes, besides the inner layer between the inner dielectric and outer conductor, a second inner dielectric and second outer conductor. A conductive cover and an outer conductive area that substantially enclose the components on the card are set to shield potential via the second outer conductor and connector.

    • A probe station includes a fully guarded chuck assembly and connector mechanism for increasing sensitivity to low-level currents while reducing settling times. The chuck assembly includes a wafer-supporting first chuck element surrounded by a second chuck element having a lower component, skirting component and upper component each with a surface portion extending opposite the first element for guarding thereof. The connector mechanism is so connected to the second chuck element as to enable, during low-level current measurements, the potential on each component to follow that on the first chuck element as measured relative to an outer shielding enclosure surrounding each element. Leakage current from the first chuck element is thus reduced to virtually zero, hence enabling increased current sensitivity, and the reduced capacitance thus provided by the second chuck element decreases charging periods, hence reducing settling times. With similar operation and effect, where any signal line element of the connector mechanism is arranged exterior of its corresponding guard line element, such as adjacent the chuck assembly or on the probe-holding assembly, a guard enclosure is provided to surround and fully guard such signal line element in interposed relationship between that element and the outer shielding enclosure.
