Standard operating procedures of the Eddy Current tool in SNF. The LEI1500 Eddy current system measures sheet conductance (mhos/square) as a proportional DC voltage, before and after moving the sample under the sensing coil with magnetic field. This allows contactless measurement of Sheet Resistance by Eddy current. It measures bulk samples or films of sheet resistance from below 0.1ohm/sqr to above 3000ohm/sqr on high resistivity substrates within 900um thickness. Sample size up to 8” wafers, Sensor Transducer Size 14 mm diameter (spot size). Learn more about Stanford nano facilities at nanolabs.stanford.edu/
