The Keithley 7072-HV is a high voltage semiconductor matrix card designed to switch low-level, high-voltage, and high-impedance signals for semiconductor parametric tests on wafers and devices. It provides an 8 row by 12 column matrix configuration with three-lug triaxial connectors carrying Signal, Guard, and Chassis conductors, where the outer shell is connected to chassis for safety and noise shielding and the center conductor is fully surrounded by the inner conducting shield to provide fully guarded measurements with higher isolation and improved measurement speed and accuracy.
The 7072-HV is intended for semiconductor device and material characterization. The high voltage signals encountered in breakdown measurements or oxide integrity testing can be switched with this matrix card, with signals connected to the High V, Low I paths automatically isolated from the rest of the card. The two C-V paths may be used for measurement of capacitance voltage characteristics from DC to 1 MHz or for switching low currents with a common ground. Four additional high quality signal paths with less than 20 pA offset current provide for signal switching to 200 V.
Keithley Instruments was founded in 1946 in Cleveland, Ohio and became a long-established specialist in low-level and precision electrical measurement. Keithley was acquired by Danaher Corporation in 2010 and, following the 2016 spinoff of Danaher's industrial businesses, is now part of Fortive Corporation alongside Tektronix. Instruments bearing the Keithley brand continue to be developed and supported under that lineage.
