Abstract:
1. A system for providing electron beam lithography image enhancement, comprising: an electron beam lithography tool; an electron microscope positioned below a lithography stage of the electron beam lithography tool, the stage of the electron beam lithography tool including an aperture suitable for providing the electron microscope line-of-sight to one or more lithography optics of the electron beam lithography tool, the electron microscope including one or more magnifying lenses oriented about the optical axis of the electron microscope; a translation unit configured to selectively translate the electron microscope along the optical axis of one or more lithography optics of the electron beam lithography tool responsive to a translation control system, the translation unit further configured to position the electron microscope in an operational state such that one or more optics of the electron microscope are positioned proximate to the one or more lithography optics, the one or more magnifying lenses of the electron microscope configured to magnify a virtual sample plane image generated by the electron beam lithography tool.
