    摘要: An electron device capable of evaluating a sample at high throughput and high S/N. An electron beam emitted from an electron gun is irradiated, through an electrostatic lens (4-1), an objective lens (11-1), etc., in a diagonal direction on a sample (W) placed on an X-Y-theta stage (9-1), and secondary electrons or reflected electrons are discharged from the sample (W). The incident angle of the primary electron beam is set to about not less than 35º and less than 90º by controlling a polarizer (8-1). The electrons discharged from the sample (W) are guided in the vertical direction to form an image on a detector.

    摘要: The present invention relates to a charged particle device with improved detection scheme. The device has a charged particle source (1) providing a beam of primary charged particles; a first unit (5) for providing a potential; a second unit (7) for providing a potential; and a center unit (6) positioned between the first unit (5) and the second unit (7). The center unit is capable of providing a potential different from the potential of the first and the second unit for decelerating the primary charged particles to a first low energy and for accelerating the primary charged particles to a second high energy. Therein, the first unit (5) and/or the second unit (7) is a detector for detecting secondary electrons released at a specimen (4).

    摘要: An aberration-correcting microscopy instrument is provided. It has a first magnetic deflector (206) disposed for reception of a first non-dispersed electron diffraction pattern. The first magnetic deflector is also configured for projection of a first energy dispersed electron diffraction pattern in an exit plane (A2) of the first magnetic deflector. An electrostatic lens (224) is disposed in the exit plane of the first magnetic deflector. A second magnetic deflector (222) substantially identical to the first magnetic deflector is disposed for reception of the first energy dispersed electron diffraction pattern from the electrostatic lens. The second magnetic deflector is also configured for projection of a second non-dispersed electron diffraction pattern in a first exit plane (B2) of the second magnetic deflector. An electron mirror (226) is configured for correction of one or more aberrations in the second non-dispersed electron diffraction pattern. The electron mirror is disposed for reflection of the second non-dispersed electron diffraction pattern to the second magnetic deflector for projection of a second energy dispersed electron diffraction pattern in a second exit plane (B3) of the second magnetic deflector.

    摘要: By applying a voltage or signal and withdrawing or injecting, an electron or electrons to a layer of material (26, 26'), it is possible to write, erase or read data electrochemically. The layer of material has at least one portion that will reversibly change between charge states in response to the applied voltage or signal and the withdrawal or injection of an electron or electrons. Alternatively, the material of the layer may be such that the portion of the layer of material will dissociate into components in response to the applied voltage or signal and injection or withdrawal of an electron or electrons. The stored data may be read using a scanning tunneling microscope (STM) by applying a voltage or signal (40) thereto and detecting the current (i) through, voltage across or signal reflected from the layer to detect the different charge states or structures of different portions of the layer. The signal or voltage (702) applied can be a DC or AC signal, a signal pulse or transient or various combinations thereof. By using a material with more than two charge states or with multiple locations each with different charge states and by applying a signal with and detecting at a single or multiple frequencies, it is possible to write, erase or read multiple bits of information simultaneously.

    摘要: Disclosed is an apparatus for inspecting a sample. The apparatus includes a first electron beam generator arranged to direct a first electron beam having a first range of energy levels toward a first area of the sample and a second electron beam generator arranged to direct a second electron beam having a second range of energy levels toward a second area of the sample. The second area of the sample at least partly overlaps with the first area, and the second range of energy levels are different from the first range such that charge build up caused by the first electron beam is controlled. The apparatus further includes a detector arranged to detect secondary electrons originating from the sample as a result of the first and second electron beam interacting with the sample.
