Abstract: Provided are a position detection apparatus and a position detection method capable of detecting a position of plasma on a target. The position detection apparatus according to the present disclosure includes: a visible light optical system configured to condense visible light generated together with EUV light from plasma generated by condensing laser light onto a target with a condensing lens; a position detection sensor configured to detect the visible light condensed by the visible light optical system; and a position detection processing unit configured to detect a change in a position of the plasma on the target, from a change in a spot of the visible light detected by the position detection sensor.

Abstract: An inspection device according to the present disclosure includes a detector for inspection that includes a plurality of pixels arranged on a light receiving surface and acquires image data by transferring charge produced by light received by the plurality of pixels in a transfer direction at a specified transfer timing, a light source that emits illumination light including pulsed light, a pulse enable circuit that controls emission timing for the light source to emit the illumination light based on the transfer timing, an illumination optical system that illuminates an object to be inspected with the illumination light, a condensing optical system that condenses, on the detector for inspection, light from the object to be inspected illuminated with the illumination light, and a processing unit that inspects the object to be inspected by using the image data of the object to be inspected.

Abstract: A detection method, an inspection method, a detection apparatus, and an inspection apparatus capable of preventing an error in a luminance unevenness correction and thereby accurately inspecting an object to be inspected are provided. A detection method according to the present disclosure includes illuminating an object to be inspected by using illumination light including pulsed light, acquiring image data of the object to be inspected by concentrating light from the object to be inspected illuminated by the illumination light and detecting the concentrated light by an inspection detector, acquiring image data of a luminance distribution of the illumination light, the luminance distribution being detected by illuminating a correction detector by using part of the illumination light, and detecting inspection image data by correcting the image data of the object to be inspected based on the image data of the luminance distribution.

Abstract: In a method of manufacturing oxide thin film by adsorbing or depositing oxide forming starting material on a substrate followed by oxide formation, by using water in a liquid state to manufacture the oxide thin film, the advantages of the ALD method are utilized while resolving the tendency to leave impurities in the oxide film produced that is a drawback thereof, so that oxide thin film can be obtained having a reduced concentration of impurities.
