    摘要: The object of the present invention is to provide a method for solving the problem of surface damage due to gallium ion irradiation that poses a problem when carrying out mask repair using currently established FIB techniques, and the problem of residual gallium, and to provide a device realizing this method. The device of the present invention has an electron beam lens barrel that can carry out processing, as well as an FIB lens barrel, provided inside the same sample chamber, which means that a mask repair method of the present invention, in correction processing to remove redundant sections such as a mask opaque defect, phase shift film bump defect or a glass substrate cut remnant defect, comprises a step of coarse correction by etching using a focused ion beam and a step of finishing processing using an electron beam, to remove surface damage due to gallium irradiation, and residual gallium.

    摘要: An apparatus for processing and observing a sample has a sample stage for supporting a sample at a preselected location thereof, a focused ion beam irradiation system for irradiating the sample with a focused ion beam along an optical axis to cut out a portion from the sample, and a side entry stage disposed over the sample stage and extending slantingly with respect to the optical axis of the focused ion beam irradiated by the focused ion beam irradiation system. The side entry stage has a microscope sample holder for picking up the cut-out sample portion directly from the preselected location of the sample and for supporting the sample portion. The microscope sample holder is configured to be removed from the side entry stage while supporting the sample portion and to be connected to an entry stage of a microscope device for observing the sample portion.

    摘要: A liquid metal ion source has an emitter electrode for emitting ions, an extraction electrode, proximate the emitter electrode for generating a focused electric field at a tip of the emitter electrode, and a suppression electrode proximate the extraction electrode for adjusting the strength of the focused electric field generated at the tip of the emitter electrode so that metal ions are extracted from liquid metal covering the tip of the emitter electrode at a desired emission current value. A storage device stores a function defining a relationship between variation (&Dgr;Ie) in current of the emitter electrode and variation (&Dgr;Vsup) in voltage of the suppression electrode as a function &Dgr;Ie=F(&Dgr;Vsup), with the voltage (Vext) of the extraction electrode being at a fixed value. A control apparatus controls voltages of the extraction and suppression electrodes and the emission current, detects the variation &Dgr;Vsup in the voltage (Vsup) of the suppression electrode when a voltage (Vext) of the extraction electrode is made to vary by only &Dgr;Vext with the current of the emitter electrode being held to a fixed value, and calculates flow impedance &Dgr;Vext/&Dgr;Ie using the voltage variation amounts &Dgr;Vext and &Dgr;Vsup and the function acquired form the storage device.

    摘要: A method for obtaining an image of a sample surface using a charged particle beam apparatus without damaging the sample surface is performed by scanning a focused ion beam onto an observation region of the sample surface, detecting secondary charged particles emanating from the sample surface, and producing an image in response thereto. The sample is placed in a water vapor atmosphere while being scanned by the focused ion beam so that a water vapor absorption layer is formed in the observation region of the sample surface. A SIM image is obtained by placing the periphery of the portion to be processed into a water vapor atmosphere and then irradiating and scanning across the sample surface with the focused ion beam in order to prevent damage to the sample surface. In one embodiment, a focused ion beam instrument is used to observe and repair a photomask without damaging the underlying substrate or to the photomask pattern during observation.
