In a defect inspecting apparatus, having contrast, brightness and appearance of a target for inspection and detection sensitivity of a defect changed depending on optical system conditions, and adapted to perform inspection by selecting an optimal test condition, even an unskilled user can easily select an optimal optical condition by quantitatively displaying evaluation values side by side when optical system conditions are changed. Moreover, by selecting an evaluation item having highest satisfaction based on a result of a series of test inspection, an optimal test condition can be automatically selected.

Provided is a method of analyzing a surface three-dimensionally in which compositions of a surface and an inner of a specimen are analyzed in three dimensions in a device having a beam source; a monochromator which separates a specific-wavelength beam from a multi-wavelength beam emitted from the beam source and irradiates the detected specific-wavelength beam into the specimen; a detector which analyzes energy of photoelectrons that are excited and escaped from the specimen, the method comprising: irradiating the specific-wavelength beam into one region of the surface of the specimen to measure intensities of the excited photoelectrons depending on escape angles between a normal line to the surface of the specimen and the escape directions of the excited photoelectrons, and detecting a composition distribution depending on a depth of the one region of the specimen by using data on the intensities that are measured depending on the escape angles of the excited photoelectrons; changing an incident position of the specific-wavelength beam for the specimen to detect the composition distribution depending on the depth at each of positions of the surface of the specimen; and collecting data on the composition distribution depending on the depth at each of the positions of the specimen to analyze the compositions of the specimen in the three dimensions.

Titanium resistant to discoloration in an atmospheric environment characterized by having an average carbon concentration of 14 at % or less in a range to a depth of 100 nm from the surface and having an oxide film of a thickness of 12 to 40 nm at its surface. Titanium resistant to discoloration in an atmospheric environment characterized in that, in X-ray diffraction of its surface, a ratio (X1/X2) of a (200) peak intensity X1 of TiC to a (110) peak intensity X2 of titanium is not more than 0.18 and by having an oxide film of a thickness of 12 to 40 nm at its surface.
摘要:
A method of Auger Electron Spectroscopic (AES) analysis for a surface of an insulating sample. The method is characterized by performing an AES analysis after depositing a conductive layer of a designated thickness on the surface of a sample containing an insulating layer by means of an ion beam sputtering for the purpose of the preventing charge accumulation. The conductive layer preferably is deposited to have a thickness of at least 6 .ANG. to 50 .ANG. and a beam voltage used for applying the conductive layer is at least 3 Kev. The conductive layer is made of any of iridium(Ir), chrome(Cr) and gold(Au). Because any electron charge generated on the sample is discharged via the conductive layer, the AES analysis can be performed for a sample containing an insulating layer.

A scanning photoelectron microscope comprises a stage on which a sample is placed in a state in which gas around the sample is present, a light source emitting light of a wavelength capable of causing photoelectrons to be emitted from the sample, an optical system for condensing the light from the light source on the sample, scanning means for scanning the sample and the light relative to each other, and detecting means capable of applying positive potential to the sample, and detecting the photoelectrons created from the sample by the condensing, through the gas.

A focused electron/bombarded (FEB) ion detector comprising an MCP, focusing means, and a collection anode disposed in a detector body. The collector anode includes a diode for receiving the focused output electron beam from the MCP. The gain between the input ion current to the MCP and the detector output signal from the diode is on the order of 1-100 million, depending on the device configuration and applied biasing voltages. A hybrid photomultiplier tube includes a photocathode, a photodiode for collecting and multiplying electrons emitted by the photocathode and providing an output signal and electrodes for focusing the electrons on the photodiode. A vacuum envelope encloses a vacuum region between photocathode and the detector. A conductor disposed on or adjacent to a sidewall of the vacuum envelope reduces the effect of electrical charges on the inside wall of the vacuum envelope on the trajectories of the electrons.
摘要:
The quality of a lubricant layer formed on a surface of a magnetic recording medium is determined by exposing the lubricant molecules of the lubricant layer to a radiation source for x-ray photoelectron spectroscopy while varying the photoelectron drawing angle. The number of emitted electrons is determined and, from this, the degree of orientation and the quality of the lubricant layer is found.

An object (12) is irradiated by means of a divergent and polychromatic beam of X-rays for producing a diagram composed of Kikuchi pseudo-lines. An X-ray generator (4) is mounted on a stand (1), and an automatic handler (13) presents the objects (12) in confronting relation to the microfocus (F) of the generator. An intensity amplifier (6) and a video camera (7) record the obtained diagrams composed of the pseudo-lines. The handler apparatus is controlled by an electronic device (17).
摘要:
For observing material structures and/or dynamic processes at surfaces, the known scanning tunneling microscope (STM) is combined with a photoexcitation process leading to photon-assisted tunneling. Thereby, the very fine spatial resolution of the STM is combined with the picosecond or even femtosecond time resolution of laser pulses. The tunnel tip of a scanning tunneling microscope is positioned at tunnel distance with respect to the surface of the sample to be investigated, with an appropriate potential applied across the gap between the tunnel tip and the sample. The tunneling current is gated by means of at least one pulsed laser beam directed at the tuneling region and/or at the tunnel tip.
