    摘要: An X-ray analyzing method includes the steps of applying an irradiated electron beam, converged by a condenser lens and an objective lens into a thin beam, to the inside of a fine hole existing on the surface of a sample; observing X-rays generated from a residual substance existing inside the fine hole; and performing a qualitative and quantitative analysis of the residual substance. The X-rays are observed by an X-ray detector installed in an internal space of the condenser lens, an internal space of the objective lens, or between the condenser lens and the objective lens, by detecting only the X-rays radiated within the angular range -.theta. to +.theta., where .theta. is an angle formed with a center axis of the electron beam, and so defined that tan .theta. is substantially equal to a/d, where a and d are the radius and the depth of the fine hole, respectively.

    摘要: A secondary ion mass spectrometer including primary ion emitting means for generating a primary ion to irradiate a specimen with the primary ion, means for separating secondary ions sputtered from the specimen, in accordance with mass-to-charge ratios, and detection means for detecting a secondary ion current emerging from the secondary ion separating means is disclosed, in which, when the value of the secondary ion current becomes greater than the upper limit of the dynamic range of the detecting means, the secondary ion current is attenuated by an attenuator, and the value of secondary ion current detected by the detection means is divided by the attenuation factor of the attenuator to obtain a corrected value. Thus, the secondary ion mass spectrometer is prevented from producing an erroneous analytical result due to the saturation of the detection means, that is, has a wide dynamic range, in which the amount of secondary ion varies by eight to ten orders of magnitude. Accordingly, the sescondary ion mass spectrometer can quantitatively determine a high-concentration element and a considerably-low-concentration element at the same time, and can determine the concentration distribution of an analytical element in a wide concentration range from a large value to a considerably small value.

    摘要: An ion source includes an ion source material holder adapted to load an ion source material thereon and having an aperture at the bottom thereof, an ion emitter mounted on the ion source material holder at the aperture, heating means for heating the ion source material holder and the ion emitter, and an ion extracting electrode for extracting an ion beam from the ion emitter. The ion emitter is made of a mixture of a material having a large work function and a material having a small work function, in order to be able to emit both positive ions and negative ions from the ion emitter. The polarity of a voltage applied between the ion emitter and the ion extracting electrode is changed so that one of the positive ion beam and the negative ion beam can be selectively extracted from the ion emitter.

    摘要: The apparatus for ion beam fabrication, which has been able to detect any anomalous condition of ion beams only by means of the current irradiated on the specimen, could not compensate the failure by investigating the cause and could not realize stable processing. To solve the problem described above, the present invention includes the first and second blankers and Faraday cups switches ON and OFF the first and second blankers and monitors beam current at two positions above and below the projection mask. By adopting this configuration, it will be possible to acquire the information on failure in ion beam, sort out the cause of the failure and to compensate the failure while limiting damages to the projection mask. As a result, it will be possible to realize stable processing by means of ion beam, and to use the ion beam fabricating device on a stable basis.

    摘要: Certain film deposition and selective etching technology may involve scanning of a charged particle beam along with a deposition gas and etching gas, respectively. In conventional methods, unfortunately, the deposition rate or the selective ratio is oftentimes decreased depending on optical system setting, scan spacing, dwell time, loop time, substrate, etc. Accordingly, an apparatus is provided for finding an optical system setting, a dwell time, and a scan spacing. These parameters are found to realize the optimal scanning method of the charged particle beam from the loop time dependence of the deposition rate or etching rate. This deposition rate or etching rate are measurements stored in advance for a desired irradiation region where film deposition or selective etching should be performed. The apparatus displays a result of its judgment on a display device.
