    摘要: Ultra-low concentrations of impurities such as water in a highly-purified gas are analyzed by a system having an ion source chamber and a drift chamber. The ion source chamber ionizes one of a sample gas and a carrier gas to produce main component ions, and the other of the sample gas and carrier gas is introduced into the drift chamber. The invention controls the residence time of main component ions in one of the first and second chambers to be shorter than the mean reaction time of main component ions and impurity molecules of the sample gas in the one of the first and second chambers.

    摘要: A transmission electron microscope makes it possible to search for defects without applying an undesirable treatment to a specimen by using a reference specimen prepared separately from a specimen to be observed. A pair of specimen holders detachable from the column of the electron microscope are adjacently arranged at upper and lower stages respectively along an electron beam axis to position the specimens closely to each other in an electron beam illuminating position. The pair of holders can be independently set to or removed from the electron beam illuminating position. The specimen holders include devices for selectively finely adjusting the spacing between the specimens, the angle of the specimen with respect to the electron beam axis and with respect to a plane perpendicular to the electron beam axis.

    摘要: A mass spectrometer for analyzing trace impurities on a level between ppt and ppb contained in silicon material gas such as monosilane gas. The mass spectrometer includes an ion formation region, reaction region, and mass analysis region. Ion formation gas is introduced into the ion formation region and sample gas (silicon material gas) is introduced into the reaction region. The ion formation region ionizes ion formation gas by an ionizer and forms primary ions. When the pressure of ion formation gas is made higher than the pressure of sample gas, the ion formation gas flows into the reaction region from the ion formation region together with primary ions and is mixed with the sample gas. In the reaction region, an ion-molecule reaction is produced between the primary ions and trace impurities contained in the sample gas and the trace impurities contained in the sample gas are ionized. The ion intensity of trace impunities, the concentration of trace impurities in the sample gas is determined using a calibration curve. When the gas pressure in the reaction region is kept at almost 1 atmosphere, the reaction is promoted and when the ion-molecule reaction time is optimized according to the size of the reaction region and the voltage condition, impurities on a level between ppt and ppb can be detected and determined.

While irradiating the specimen with an electron beam, currents flowing in the probes are measured. Signals from at least two probes are input to a differential amplifier. An output of the differential amplifier is amplified. On the basis of the amplified output and scanning information of the electron beam, an absorbed current image is generated. According to the invention, a clear absorbed current image can be obtained without involving the difference in gain of amplifier between inputs. Thus, measurement efficiency in a failure analysis of a semiconductor device can be improved.

    摘要: An X-ray analyzing method for inspecting opening states of fine holes comprises the steps of: irradiating a finely converged electron beam into a first fine hole, observing an X-ray emitted from the inside of said first fine hole in order to obtain an first X-ray analysis data about the residue substance existing at the bottom of said first fine hole; irradiating a finely converged electron beam into a second fine hole, observing an X-ray emitted from the inside of said second fine hole in order to obtain an second X-ray analysis data about the residue substance existing at the bottom of said second fine hole; and comparing said first X-ray analysis data with said second X-ray analysis data, forming a judgment as to whether or not a difference between said first and second analysis data is smaller than a predetermined threshold value and using an outcome of said judgment to determine the opening states of said first and second fine holes. The X-ray observations are carried out by detecting only the X-rays emitted within the angular range -.theta. to +.theta. where notation .theta. is an angle formed with a center axis of the irradiated electron beam and so defined that tan .theta. is equal to a/d whereas notations a and d are the radius and the depth of the fine holes.
