TERAHERTZPRUFVORRICHTUNG UND PRUFVERFAHREN

摘要

An inspection apparatus including a transmission line for propagating an electromagnetic wave; an electromagnetic wave supply unit for supplying a terahertz wave to the transmission line; an electromagnetic wave detection unit for detecting the terahertz wave from the transmission line; a conductive region; an inspection object supply unit; and a deposition unit. The conductive region is arranged at a site including at least a part of the range to which an electric field distribution of the electromagnetic wave propagating through the transmission line extends. The inspection object supply unit holds and supplies the inspection object to the outside, and the deposition unit deposits the inspection object selectively on the conductive region by electrostatic force. The electromagnetic wave supplied from the electromagnetic wave supply unit and propagated through the transmission line is detected by the electromagnetic wave detection unit to obtain information on the inspection object.
