    摘要: A charged particle beam apparatus for acquiring high-definition and highly contrasted observation images by detecting efficiently secondary signals without increasing aberration of the primary electron beam, detecting defects from observation images and thus increasing the inspection speed and enhancing the sensitivity of inspection. The desired area of the sample is scanned with a primary charged particle beam, and the secondary charged particles generated secondarily from the area by the irradiation of the primary charged particle beam are led to collide with the secondary electron conversing electrode, and then the secondary electrons generated by the first E×B deflector 31 arranged through an insulator on the surface of the secondary electron conversing electrode on the side of the sample is absorbed by the detector. At the same time, the deflection chromatic aberration that had been generated in the primary charged particle beam by the first E×B deflector is reduced by the second E×B deflector arranged on the first E×B deflector, to obtain high-definition and highly contrasted observation images free of shading.

    摘要: An apparatus for a charged particle beam has a charged particle source; a charged particle optical system for focusing and deflecting a charged particle beam emitted from the charged particle source; a detector for detecting secondary particles emitted from a sample irradiated with the charged particle beam; and a sample holder on which the sample is mounted. The apparatus has an electrode for preventing charging which is provided so as to be movable with respect to the surface of the sample holder, and a controller for the electrode for preventing charging, which controls a voltage to be applied to the electrode for preventing charging and the movement. Preventing the charging is performed by generating an induced current or a current between an area irradiated with the charged particle beam in the sample and the electrode for preventing charging.

    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.

    摘要: An apparatus and method for observing a sample that is capable of making observations by irradiating an electron beam to a sample in the form of a thin film, and making elemental analysis accurately and with increased resolution while reducing background noise. A particular portion of the sample is observed by the electron beam by disposing a light element piece having a hole provided immediately behind the thin film sample. According to the present invention, it is possible to reduce the x-rays generated from portions other than the sample and electron beam incident on the sample after being scattered to portions other than the sample when observing the thin film sample by irradiating the electron beam. It is therefore possible to make secondary electron observation and elemental analysis with increased accuracy and sensitivity. Thus, an apparatus and a method for observing samples is provided that allows for the accurate and high-resolution internal observation of LSI devices.
