发明名称 Dual photo-acoustic and resistivity measurement system
摘要 A measurement system for measuring aspects of a wafer combines an apparatus for performing a conductivity measurement, such as a four-point probe system, with apparatus for performing an optical measurement, such as a photoacoustic measurement system. Results are obtained and combined to provide comprehensive data sets describing the characteristics of the thin film substrate therein.
