Measurements of bulk resistivity of silicon wafers were made at NIST with 5 probing instruments on each of 5 days. The wafers were doped with phosphorous by neutron transmutation doping in order to have nominal resistivities of 200 ohm.cm. Each data point is the average of 6 measurements at the center of each wafer. Measurements were carried out with four-point DC probes according to ASTM Standard F84-93, "Standard Method for Measuring Resistivity of Silicon Wafers with an In-Line Four-Point Probe."
