Inspection apparatus and inspection method
First Claim
1. An inspection apparatus, comprising:
- a transmission line for propagating an electromagnetic wave;
an electromagnetic wave supply unit for supplying the electromagnetic wave to the transmission line, the electromagnetic wave being included in a wavelength range between 30 GHz and 30 THz;
an electromagnetic wave detection unit for detecting the electromagnetic wave from the transmission line;
a conductive region arranged in a site that includes at least a part of a range to which an electric field distribution of the electromagnetic wave propagating through the transmission line extends;
an inspection object supply unit for holding and supplying an inspection object to an outside; and
a deposition unit for depositing the inspection object supplied from the inspection object supply unit selectively on the conductive region by an electrostatic force,wherein the electromagnetic wave that is supplied from the electromagnetic wave supply unit and is propagated through the transmission line is detected by the electromagnetic wave detection unit to obtain information on the inspection object.

Abstract
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.

7. An inspection method of detecting an electromagnetic wave in a wavelength range between 30 GHz and 30 THz which is propagated through a transmission line to obtain information on an inspection object deposited on a conductive region located in a site including at least a part of a range to which an electric field distribution of the electromagnetic wave propagating through the transmission line extends, comprising:
-
supplying the inspection object from an inspection object supply unit for holding and supplying the inspection object to an outside; applying a voltage between the conductive region and an inspection object holding portion of the inspection object supply unit to generate an electric field; and guiding the supplied inspection object with an electrostatic force to deposit the object depositing selectively on the conductive region. - View Dependent Claims (8, 9, 10)
