Profile: Reedholm Instruments Co. manufactures dc test systems used by semiconductor manufacturers to make measurements on electrical test structures. We also offer integrated sensors, GaAs circuits, CCDs and discrete transistor. The RI-2kV/5A is a fully integrated dc test system configured for high volume testing. Contact to the wafer backside is through kelvin sensing leads capable of ±5A and +2kV. Instrumentation is built into the base of a high-speed prober that has been altered to be insensitive to catastrophic device breakdown. A data driven applications environment eliminates programming so that engineers responsible for the system and for interpreting its output are not diverted from device & process engineering. The 16-bit digital multimeter provides differential voltage measurements using an active metering technique which provides virtually zero voltage burden while measuring currents up to ±200mA. Used in conjunction with current sources, currents to ±500mA can be measured. Voltage measurement span is ±100V with current burden of tens of picoamperes.
