    Abstract: A near-field detection system includes include an electric field generator configured to apply an electric field to an analysis sample, a probe configured to detect a near field that has passed through the analysis sample, a current detector connected to the probe, and a laser system irradiating a laser to each of the electric field generator and the probe. The probe includes a cantilever substrate, an antenna electrode on the cantilever substrate, an electromagnetic wave blocking layer exposing a sensing region of the cantilever substrate, the electromagnetic wave blocking layer including a conductive material, and an insulating layer interposed between the cantilever substrate and the electromagnetic wave blocking layer such that the insulating layer is between the antenna electrode and the electromagnetic wave blocking layer.

    Abstract: A wafer inspection apparatus includes a support structure including a frame and vacuum chucks mounted thereon, each vacuum chuck having a support surface including a vacuum suction portion, the support structure configured to structurally support a wafer on one or more vacuum chucks, the frame defining an opening larger than an area of the wafer. The wafer inspection apparatus includes an electromagnetic wave emitter configured to irradiate an inspection electromagnetic wave to the wafer, a sensor configured to receive the inspection electromagnetic wave from the wafer based on the inspection electromagnetic wave passing through the wafer, and a driver configured to move at least one of the electromagnetic wave emitter or the frame to change an irradiation location of the wafer. Each vacuum chuck is configured to be selectively movable between a first location and a second location in relation to the frame.
