Abstract:
The present invention provides an electron microscope device, comprising a scanning electron microscope 2 provided with scanning means 10 for scanning an electron beam and an electron detector 12 for detecting an electron 11 issued from a specimen 8 where the electron beam is projected for scanning, wherein a scanning electron image is acquired based on a detection result from the electron detector, wherein the electron detector comprises a fluorescent substance layer for performing photoelectric conversion, a wavelength filter giving restriction so that all or almost all of wavelength ranges of fluorescent lights from the fluorescent substance layer can be transmitted, and a wavelength detecting element for receiving the fluorescent light transmitted through the wavelength filter and for performing photoelectric conversion.
Abstract:
An electrostatic chuck protection method includes providing an exposed chuck surface with a protective surface for preventing adherence of foreign materials including a substance exhibiting volatility in a vacuum environment, and removing the protective surface in order to perform a process of forming a substrate electrostatically held on the chuck surface with a surface layer including a substance having volatility in a vacuum chamber. The protective surface may be provided when a low vacuum pumping mode of operation is performed in a vacuum environment surrounding the chuck surface.
