摘要： A method prepares a microsample from a volume sample using multiple particle beams. The method includes providing a volume sample in the microscope system, wherein the interior of the volume sample has a sample region of interest, and producing a macrolamella comprising the sample region of interest by removing sample material of the volume sample using one of the particle beams. The method also includes orienting the macrolamella relative to one of the particle beams, and removing sample material of the macrolamella via a beam so that the region of interest is exposed.

摘要： The present invention provides apparatuses to inspect small particles on the surface of a sample such as wafer and mask. The apparatuses provide both high detection efficiency and high throughput by forming Dark-field BSE images. The apparatuses can additionally inspect physical and electrical defects on the sample surface by form SE images and Bright-field BSE images simultaneously. The apparatuses can be designed to do single-beam or even multiple single-beam inspection for achieving a high throughput.

摘要： A method includes: generating a multiplicity of particle beams such that the particle beams penetrate a predetermined plane side-by-side and have within a volume region around the predetermined plane in each case one beam focus; scanning a first region of the surface of an object with the particle beams and detecting first intensities of particles produced by the particle beams while setting an operating parameter of the multi-beam particle microscope; and determining first values of an object property based on the first intensities. The first values represent the object property within the first region, and the object property represents a physical property of the object. The method also includes determining a second value of the operating parameter for use for a second region of the surface based on the first values of the object property.

摘要： A charged particle beam apparatus with improved depth of focus and maintained/improved resolution has a charged particle source, an off-axis illumination aperture, a lens, a computer, and a memory unit. The apparatus acquires an image by detecting a signal generated by irradiating a sample with a charged particle beam caused from the charged particle source via the off-axis illumination aperture. The computer has a beam-computing-process unit to estimate a beam profile of the charged particle beam and an image-sharpening-process unit to sharpen the image using the estimated beam profile.

摘要： Charged particle beam imaging and measurement systems are provided using gas amplification with an improved imaging gas. The system includes a charged particle beam source for directing a charged particle beam to work piece, a focusing lens for focusing the charged particles onto the work piece, and an electrode for accelerating secondary electrons generated from the work piece irradiation by the charged practice beam, or another gas cascade detection scheme. The gas imaging is performed in a high pressure scanning electron microscope (HPSEM) chamber for enclosing the improved imaging gas including CH3CH2OH (ethanol) vapor. The electrode accelerates the secondary electrons though the CH3CH2OH to ionize the CH3CH2OH through ionization cascade to amplify the number of secondary electrons for detection. An optimal configuration is provided for use of the improved imaging gas, and techniques are provided to conduct imaging studies of organic liquids and solvents, and other CH3CH2OH-based processes.
