Claim One:
1. A method of optically determining a substantially fully activated doping profile, the substantially fully activated doping profile being characterized by a set of physical parameters, the method comprising: obtaining a sample comprising a fully activated doping profile and a reference; obtaining photomodulated reflectance (PMOR) offset curve measurement data and DC reflectance measurement data for the sample comprising the fully activated doping profile and for the reference; and determining values for the set of physical parameters of the doping profile based on both the photomodulated reflectance offset curve measurements and the DC reflectance measurements, wherein determining the set of physical parameters of the doping profile comprises determining from the photomodulated reflectance offset curve measurement data on the sample and from the DC reflectance measurement on the sample at least one of a junction depth X j , an active doping concentration N act and a profile abruptness or backside slope S act .
