  • Patent number: 5179333
    Abstract: A semiconductor wafer evaluation apparatus, wherein a conductivity detector and a carrier mobility detector are independently arranged so that detections can be made under optimum conditions, respectively. A wafer carrying unit is arranged so as to carry or convey a semiconductor wafer on a carrying path between the two detectors. These components are controlled by a controller. A carrier concentration is calculated from the conductivity and the carrier mobility detected by both detectors. When a partition wall for preventing interference of an electromagnetic wave is provided between the conductivity detector and the carrier mobility detector, interference between the two detectors is further reduced.
