The Four-Point Probe is a Veeco FPP-5000 for I/V measurement. The main purpose is to measure resistance and resistivity on a 4" silicon wafer. But can also be used to find thickness of thin layers or test if is a N- or P-type wafer.

The wafer are pushed down on the four pins so a measurement is performed. It works only for 4" wafers because a special holder is need.
