SCANNING ELECTRON MICROSCOPE, AN INTERFACE AND A METHOD FOR OBSERVING AN OBJECT WITHIN A NON-VACUUM ENVIRONMENT

摘要

An interface, a scanning electron microscope and a method for observing an object that is positioned in a non-vacuum environment. The method includes: generating an electron beam in the vacuum environment; scanning a region of the object with the electron beam while the object is located below an object holder; wherein the scanning comprises allowing the electron beam to pass through an aperture of an aperture array, pass through an ultra thin membrane that seals the aperture, and pass through the object holder; wherein the ultra thin membrane withstands a pressure difference between the vacuum environment and the non-vacuum environment; and detecting particles generated in response to an interaction between the electron beam and the object.

1. A method for observing an object that is positioned in a non-vacuum environment, the method comprising:
generating an electron beam in a vacuum environment of an electron microscope; scanning a region of the object with the electron beam, the scanning comprising allowing the electron beam to pass through an aperture of an aperture array, pass through an ultra thin membrane that seals the aperture, and pass through an object holder; the ultra thin membrane withstanding a pressure difference between the vacuum environment and the non-vacuum environment; detecting particles generated in response to an interaction between the electron beam and the object; and imaging the object by another microscope located outside of said vacuum environment and below the object.
