Abstract: A method includes enabling a first radiating source configured to output a first beam, enabling a second radiating source configured to output a second beam, directing the first beam to irradiate a sample at an angle of incidence of ten degrees of Brewster's angle or less, directing the second beam to irradiate a sample at an angle of incidence of ten degrees or less (the first beam and the second beam only pass through a single scan lens before irradiating the sample), measuring scattered radiation data resulting from the irradiation of the sample by the second beam, measuring reflected radiation resulting from irradiation of the sample by the first beam, and determining the presence of a defect based at least in part on one of the measurements. The radiating sources may be enabled in an alternating fashion so to improve resulting measurement performance.

Abstract: A system captures and utilizes expert knowledge in artificial intelligence. The system includes a knowledge capture module for extracting expert knowledge from subject matter experts in a conversational format and a knowledge management module for cataloging and summarizing the extracted knowledge. The system also includes a digital subject matter expert (dSME) module for ingesting the cataloged knowledge and using it to guide users in building AI models. A chatbot interacts with a user and selects the appropriate dSME module that is relevant to the user request. The system attempts to answer the user request based on the dSME module. If the dSME module lacks knowledge to solve the problem, the system uses a set of tools, for example, internet based search engine to solve the problem.

Abstract: An angle independent optical surface inspector capable of generating a light beam, directing the light beam to a sample, and de-scanning a reflected light beam that is reflected from the sample, thereby generating a first de-scanned light beam. The de-scanning is performed at approximately one focal length of a de-scanning lens from an irradiation location where the light beam irradiates the sample. The optical inspector also capable of focusing the first de-scanned light beam, thereby generating a focused light beam, and measuring the location of the focused light beam. The measuring of the location is performed at approximately one focal length of a focusing lens from the focusing lens. The incident angle of the light beam is within ten degrees of Brewster's angle. The focusing is performed by an achromatic lens.

Abstract: A first operation restriction portion forms a first step between the first operation restriction portion and a first operation portion. A second operation restriction portion forms a second step between the second operation restriction portion and a second operation portion. A first locking portion releases locking of a locked portion when a first push of pushing the first operation portion or a second push of pushing the second operation portion is performed. When the sheet stopper is rotated in response to the first push, a second locking portion stops the sheet stopper in a first upright state. When the sheet stopper is rotated in response to the second push, the second locking portion allows the sheet stopper to rotate beyond the first upright state. A third locking portion stops the sheet stopper in a second upright state.

Abstract: An optical scanning system including a radiating source that outputs a light beam, a time varying beam reflector that reflects the light beam through a scan lens towards a transparent sample at an incident angle of plus or minus ten degrees from Brewster's angle, a focusing lens configured to be irradiated by light scattered from the transparent sample, and a detector that is irradiated by the light scattered from the transparent sample. The detector outputs a signal that indicates an intensity of light measured by the detector. None of the light scattered from the transparent sample is blocked. The light scattered from the transparent sample is scattered from the top surface of the transparent sample, the bottom surface of the transparent sample, or any location in between the top surface of the transparent sample and the bottom surface of the transparent sample.

Abstract: A supported portion of a cover member is rotatably supported by a main support portion of a main body, and is slidable with respect to the main support portion along an extending direction of the cover member. A first joint portion of a link member is rotatably supported by a joint support portion. A second joint portion of the link member is engaged with a joint guide portion slidably along the extending direction. When the cover member is in an open position, a cover engagement portion engages with a main body engagement portion, and the second joint portion engages with a guide base end of the joint guide portion. When the cover member is in the open position, a moment load of the cover member around the second joint portion acts as a force for holding the engagement between the cover engagement portion and the main body engagement portion.

The optical scanning system causes one of the first or second source light beams to be directed towards a sample at an incident angle. The first light beam has a first wavelength, the second light beam has a second wavelength, and the first wavelength and the second wavelength are not the same.
