Abstract
A method, system, and a computer program product characterize a semiconductor. The method includes receiving longitudinal and transverse magnetoresistance measurements of a sample with first and second channels in a parallel magnetic field and receiving longitudinal and transverse magnetoresistance measurements of the sample in a perpendicular magnetic field. The method also includes subtracting the magnetoresistances measured in the parallel magnetic field from the magnetoresistances measured in the perpendicular field to obtain longitudinal and transverse magnetoresistance values Rand R. The method further includes determining, based on the values Rand R, harmonic magnetoresistance coefficients a, and a, b, and b. A method and system for semiconductor testing and characterization are disclosed as well.
