Abstract: The present invention provides an apparatus of charged-particle beam e.g. an electron microscope comprising an in-column plasma generator for selectively cleaning BSE detector and BF/DF detector. In various embodiments, the plasma generator is located between a lower pole piece of objective lens and the BF/DF detectors, but outside trajectory area of the charged-particles from the sample stage to the BF/DF detector. Cleaning decomposed biological samples or contaminants on the surface of the detectors frequently and selectively with in-situ generated plasma can prevent the detectors from performance deterioration such as losing resolution and contrast in imaging at high levels of magnification.

General electronic apparatus/device, particularly apparatus of charged-particle beam such as electron microscope, may use the electrode assembly to create an optimized pattern of electrical field within non-cylindrical channel space.

When the illumination device projects the light in the first direction, the control circuit generates a first control signal so as to control the illumination device to perform a first illumination mode. When the illumination device projects the light in the second direction, the control circuit generates a second control signal so as to control the illumination device to perform a second illumination mode different from the first illumination mode.

Abstract: A light-emitting wireless charging structure includes a base, a wireless charging module, a light-emitting element and an upper cover. The wireless charging module is disposed on the base. The light-emitting element is disposed on the base adjacent to the wireless charging module. The upper cover covers the wireless charging module and the light-emitting element. The upper cover has a lower surface facing the wireless charging module and an upper surface opposite to the bottom surface. When the light-emitting element emits light, light coming from the light-emitting element passes through the upper cover and forms a mark on the upper surface to indicate the position of the wireless charging module. When the light-emitting element is turn off or kept in an off state, either the mark that has been formed on the upper surface disappears therefrom or no any mark is ever shown on the top surface.

Abstract: The present invention provides an apparatus of charged-particle beam such as an electron microscope including a specimen table that can slide on a planar surface around the lower pole piece of the objective lens. The specimen table is confined in a specimen stage having one elastic protrusion and one or more elastic force receiving parts (e.g three permanent protrusions) that contact and press the table. When the specimen is under microscopic examination, disturbing vibration cannot generate a force sufficient to overcome the limiting friction between the specimen table and the planar surface of the objective lens. The invention exhibits numerous technical merits such as minimal or zero vibration noise, and improved image quality, among others.
