Current In-Plane Tunneling (CIPT) uses a four-point probe setup to determine characteristic properties of tunnel junctions by measuring resistance at different probe spacings. There are a number of different probe types available to enable the measurement of a large range of samples and wafers.
The Wide Probe is available with a Au coating on the pins, on either a ceramic carrier or, as is the case for the PCB-1M-005, on the PCB carrier for SmartProber Instruments.
