摘要： A detector supplement device for integration in a spectroscopy setup with the spectroscopy setup including a vacuum chamber, a light source, a sample irradiating a reflected photon beam and a charged particle beam in the same direction of propagation into a radiation detector which is able to detect ultrafast electric currents originating from charged particles. The detector supplement device includes a Rogowski coil placeable inside the vacuum chamber between the sample and radiation detector. The charged particle beam is guided through the hollow core of the Rogowski coil allowing synchronized measurements of electrical currents due to the charged particle beam correlated to the reflected photon beam, while irradiation of the reflected photon beam and the charged particle beam takes place in the same direction of propagation.

摘要： The present invention provides a surface inspection method and apparatus for inspecting a surface of a sample, in which a resistive film is coated on the surface, and a beam is irradiated to the surface having the resistive film coated thereon, to thereby conduct inspection of the surface of the sample. In the surface inspection method of the present invention, a resistive film having an arbitrarily determined thickness t1 is first coated on a surface of a sample. Thereafter, a part of the resistive film having the arbitrarily determined thickness t1 is dissolved in a solvent, to thereby reduce the thickness of the resistive film to a desired level. This enables precise control of a value of resistance of the resistive film and suppresses distortion of an image to be detected.

摘要： An electron beam inspection apparatus images reflected electrons and cancels negative charging derived from electron-beam irradiation. Ultraviolet rays are irradiated and an irradiated area of ultraviolet rays is displayed as a photoelectron image. The photoelectron image and a reflected-electron image are displayed on a monitor while being superposed on each other, to easily grasp the positional relationship between the images and the difference in size between them. Specifically, the shape of the irradiated area of an electron beam includes the shape of the irradiated area of ultraviolet rays on a display screen. The intensity of the ultraviolet rays in the irradiated area of the electron beam is adjusted while the reflected-electron imaging conditions for the reflected-electron image are sustained. Moreover, an amount-of-ultraviolet ray adjustment mechanism is controlled on the monitor so that an amount of the ultraviolet rays is adjusted while observing a reflected-electron image obtained during ultraviolet irradiation.
