摘要: A transmission electron microscope includes an electron beam source to generate an electron beam. Beam optics are provided to converge the electron beam. A specimen holder is provided to hold a specimen in the path of the electron beam. A detector is used to detect the electron beam transmitted through the specimen. The transmission electron microscope may be adapted to generate two or more images that are substantially incoherently related to one another, store the images, and combine amplitude signals at corresponding pixels of the respective images to improve a signal-to-noise ratio. Alternatively or in addition, the transmission electron microscope may be adapted to operate the specimen holder to move the specimen in relation to the beam optics during exposure or between exposures to operate the transmission electron microscope in an incoherent mode.

摘要: A compact charged-particle-beam microscope, weighing less than about 50 kg and having a size of less than about 1 m×1 m×1 m, is provided for imaging a sample. The microscope has a vacuum chamber to maintain a low-pressure environment, a stage to hold a sample in the vacuum chamber, a charged-particle beam source to generate a charged-particle beam, charged-particle beam optics to converge the charged-particle beam onto the sample, and one or more beam scanners to scan the charged-particle beam across the sample. A charged-particle detector is provided to detect charged-particle radiation emanating from the sample and generate a corresponding charged-particle-detection signal. At least one energy dispersive x-ray spectrometer (EDS) is provided to detect x-rays emanating from the sample and generate a corresponding x-ray-detection signal. A controller analyzes the charged-particle-detection signal and the x-ray-detection signal to generate an image of the sample and a histogram of x-ray energies for at least a portion of the sample.

摘要: A transmission electron microscope includes an electron beam source to generate an electron beam. Beam optics are provided to converge the electron beam. An aberration corrector comprising either a foil or a set of concentric elements corrects the electron beam for at least a spherical aberration. A specimen holder is provided to hold a specimen in the path of the electron beam. A detector is used to detect the electron beam transmitted through the specimen. The transmission electron microscope may be configured to operate in a dark-field mode in which a zero beam of the electron beam is not detected. The microscope may also be capable of operating in an incoherent illumination mode.

摘要: A transmission electron microscope is provided for imaging a sample. The microscope has a stage to hold a sample and an electron beam column to direct an electron beam onto a field of view on the sample. The electron beam column includes an electron beam source to generate an electron beam, and electron beam optics to converge the electron beam onto a field of view on the sample. The microscope also has a beam scanner to scan the electron beam across multiple fields of view on the sample. The microscope additionally has a detector to detect radiation emanating from the sample to generate an image. A controller is provided to analyze the detected radiation to generate an image of the sample.

摘要: A scanning transmission electron microscope for imaging a specimen includes an electron beam source to generate an electron beam. Beam optics are provided to converge the electron beam. A stage is provided to hold a specimen in the path of the electron beam. A beam scanner scans the electron beam across the specimen. A controller may define one or more scanning areas corresponding to locations of the specimen, and control one or more of the beam scanner and stage to selectively scan the electron beam in the scanning areas. A detector is provided to detect electrons transmitted through the specimen to generate an image. The controller may generate a sub-image for each of the scanning areas, and stitch together the sub-images for the scanning areas to generate a stitched-together image. The controller may also analyze the stitched-together image to determine information regarding the specimen.

摘要: A coater is provided for depositing a coating onto a sequence of samples to be analyzed in a microscope. The coater includes a process chamber to maintain a low-pressure vacuum or controlled gaseous environment at a deposition region inside the process chamber, a sample conveyor to support and convey samples through the deposition region, an evaporant supply to vaporize material from an evaporant source onto the samples at the deposition region, and a controller to control one or more operations of the coater.
