    Abstract: A semiconductor pattern detecting apparatus is provided. The semiconductor pattern detecting apparatus includes a stage configured to position a wafer formed with a semiconductor pattern, the stage extending in a first direction and a second direction perpendicular to the first direction, an electron emitter configured to irradiate first electrons on the semiconductor pattern, an electrode configured to generate an electric field to induce an electric potential on a surface of the semiconductor pattern, a detector configured to detect second electrons emitted from the semiconductor pattern, an imager configured to obtain a plurality of first images by using the second electrons detected by the detector, and at least one controller configured to apply a first voltage and a second voltage different from the first voltage to the electrode alternately and repeatedly and to generate a second image by combining the plurality of first images, wherein the imager is so configured that each of the plurality of first images are obtained when the first voltage is applied to the electrode.

    Abstract: According to one embodiment, a semiconductor chip inspection device includes a conveyor, an image capture device, and an analysis system. The conveyor provides a transfer path on which a semiconductor chip heated during a manufacturing process is moved. The image capture device is disposed above the transfer path and is configured to generate a thermographic image by imaging the semiconductor chip including capturing a plurality of thermographic images at different focal points in a thickness direction of the semiconductor chip. The analysis system is configured to compare the plurality of thermographic images with a plurality of standard images provided in advance, and to detect a region in which a temperature differential between a thermographic image and a respective standard image exceeds a reference value.
