    摘要: A mass analyzer includes two rotating electric field (REF) units, sinusoidal signal generators and a means for separation of dispersed ions. The REF units include a plurality of elongated electrodes surrounding a central axis, and are lined in tandem at elongated direction. Sinusoidal signals are applied to the electrodes to rotate electric fields within each REF unit. The means for separation is placed adjacent the downstream end of the 2nd REF unit. Ions enter the 1st REF unit, diverge outwards and leave the 1st REF unit on off-axis positions. The ions successively enter the 2nd REF unit and converge inwards because of 180 degrees phase difference from the 1st REF unit. Specified mass ions return to and travel along the central axis. However, unspecified mass ions deviate from the central axis and travel apart from the central axis. The means for separation separates specified ions from unspecified ions.

    摘要: A silicon drift detector used in an energy-dispersive X-ray spectrometer and having a background lower than heretofore. The detector has an X-ray detection device (1), an electrode terminal subassembly (2) for electrical connection, a Peltier device (3), and first and second shields (5,6) formed between the electrode terminal subassembly (2) and the Peltier device (3). The first shield (5) is made of a material consisting chiefly of an element having an atomic number smaller than the average atomic number of the elements included in the material of the Peltier device (3). The second shield (6) is made of a material consisting chiefly of an element having an atomic number greater than the atomic numbers of the elements included in the material of the Peltier device (3). The shields (5, 6) reduce the amount of secondary X-rays entering the X-ray detection device (1) after being produced from the Peltier device (3), the secondary X-rays being induced by X-rays transmitted through the detection device (1).

    摘要: Gas is supplied from positive pressure (10 5 Pa or more) to an analysis device of high vacuum (10 -2 Pa or less) precisely and stably, while keeping conditions constant and replicating the conditions, and performing switching to a desired gas within a short time. According to a gas introducing device and a method, a plurality of types of gases are synthesized in a mixing chamber, the synthesized gas is introduced and the pressure of the gas is reduced by a pressure reducing pump to a pressure ranging from 0.1 Pa to 0.1 MPa, and the depressurized gas is introduced to a gas analysis device through a switching operation using a gas switching valve.

    摘要: An X-ray microanalysis test system comprising a beam generator (400), which induces X-rays to emanate from a semiconductor device containing film stacks. The charged particle beam will penetrate at least two layers of a film stack (330) on a semiconductor device so that these layers may be tested. The X-rays will be detected using multiple X-ray detectors (500) that detect X-ray photons having a specific energy level. The X-rays will then be used to analyze the characteristics of the semiconductor device. Each of the multiple X-ray detectors (500) may be wavelength dispersive system (WDS) detectors. The present invention also provides a method for measuring film stack characteristics on a semiconductor device. The method for measuring includes directing an electron beam towards the semiconductor device so that the electron beam penetrates at least a conductive film layer and a liner layer, detecting the X-rays which are caused to emanate from the device with multiple X-ray detectors that detect X-ray photons having a specific energy level. The present invention also provides a method and a computer-readable medium, which determines a film stack's properties using the data collected with the test system of the present invention. The method and computer-readable medium includes selecting a set of values which estimate the film stack characteristics.
