    摘要: Provided is a micro stage comprising: a body having a vertically perforated through-hole passing through a central portion thereof; a bobbin including a tip portion with an electron emission tip embedded in the center thereof, and passing through the through-hole of the body to be moved in the through-hole along a first axis perpendicular to a vertical direction; a first piezoelectric element disposed on the body and lengthened when a voltage is applied thereto to push the bobbin in one direction along the first axis; a second piezoelectric element disposed on the body and lengthened when a voltage is applied thereto to push the bobbin in the other direction along the first axis; and an upper cover that is coupled to an upper portion of the body and has a through-hole, through which the bobbin passes and communicates with the through-hole of the body, wherein the bobbin can be positioned as desired along the first axis by adjusting the voltages applied to the first piezoelectric element and the second piezoelectric element. Accordingly, the emission tip can be exactly and stably positioned using only the movable piezoelectric elements.

    摘要: 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.
