Resistivity of semiconductor by four probe method 1. The Four- Point Probe can be used to measure film thickness, but is usually used to measure the sheet resistance of shallow layers ( as a result of epitaxy, ion- implant, diffusion or sputtering) and the bulk resistivity of bare wafers. If the thickness of a thin film is known, the sheet resistance measured by four point probe can be used to calculate the resistivity of the material; conversely, if the material' s resistivity is known, the thickness of the thin film can be calculated. If there is a minority carrier injection into the semiconductor by the current- carrying electrodes most of the carriers recombine near electrodes so that their effect on conductivity is negligible.
