Abstract

Abstract: The finite element method(FEM) is employed to calculate potential distributions of two-dimensional current fields in semiconductor sheet resistance measurements using a four-point probe and the model of calculation is presented, which has been tested and proved by calculating the potential distribution of several measurement shaped-samples. The FEM has characteristic of simpler and more common for any shape samples than the methods of electrical image and map transformation.

Key words: four-point probe, potential distribution, numerical calculation, FEM
