Abstract
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.
