    Abstract: A deceleration apparatus capable of decelerating a short spot beam or a tall. ribbon beam is disclosed. In either case, effects tending to degrade the shape of the beam profile are controlled. Caps to shield the ion beam from external potentials are provided. Electrodes whose position and potentials are adjustable are provided, on opposite sides of the beam, to ensure that the shape of the decelerating and deflecting electric fields does not significantly deviate from the optimum shape, even in the presence of the significant space-charge of high current low-energy beams of heavy ions.

    Abstract: A focused ion beam apparatus includes an ion gun unit having an emitter tip, a gas supply unit including an ion source gas nozzle configured to supply gas to the tip and an ion source gas supply source. An extracting electrode ionizes the gas adsorbed onto the surface of the tip and extracts ions by applying a voltage between the extracting electrode and the tip. A cathode electrode accelerates the ions toward a sample, and a gun alignment electrode positioned on the side of the sample with respect to the ion gun unit and adjusts the direction of irradiation of the ion beam ejected from the ion gun unit. A lens system includes a focusing lens electrode and an objective lens electrode to focus the ion beam onto the sample.

    Abstract: An improved method of directing a charged particle beam that compensates for the time required for the charged particles to traverse the system by altering one or more of the deflector signals. According to one embodiment of the invention, a digital filter is applied to the scan pattern prior to digital-to-analog (D/A) conversion in order to reduce or eliminate over-shoot effects that can result from TOF errors. In other embodiments, analog filters or the use of signal amplifiers with a lower bandwidth can also be used to compensate for TOF errors. By altering the scan pattern, over-shoot effects can be significantly reduced or eliminated.

    Abstract: The present invention relates to a deflector of a micro-column electron beam apparatus and method for fabricating the same, which forms a seed metal layer and a mask layer on both sides of a substrate, and exposes some of the seed metal layer on which deflecting plates, wirings and pads are to be formed by lithography process using a predetermined mask. The wirings and pads are formed by plating metal on the exposed portion, and some of the metal layer is also exposed on which the deflecting plates are to be formed using a predetermined mask, and then the metal is plated with desired thickness, thereby the deflecting plates are completed. Therefore, by forming plurality of deflecting plates on both sides of the substrate at the same time through plating process, alignment between the deflecting plates formed on both sides of the substrate can be exactly made, and by fabricating a deflector integrated with the substrate and deflecting plates in a batch process, productivity and reproducibility is improved. In addition, since the deflecting plates, wirings and pads are directly formed on the substrate, structural safety is improved and thereby durability is also improved.
