  • Patent number: 7459810
    Abstract: Disclosed herein is a stator of a linear motor having a plurality of outer core blocks. Each of the outer core blocks comprises first and second side core blocks and a center core block. The center core block has an inner diameter equal to an outer diameter of a coil block. Consequently, insulation and heat transfer efficiencies are improved, and the size of the linear motor is minimized. Furthermore, the center core block is provided with a heat sink part, which is inserted in the coil block for dissipating heat from the coil block. Consequently, heat generated from the coil block is effectively dissipated.

  • Publication number: 20080293215
    Abstract: Provided are methods for fabricating semiconductor devices incorporating a fin-FET structure that provides body-bias control, exhibits some characteristic advantages associated with SOI structures, provides increased operating current and/or reduced contact resistance. The methods for fabricating semiconductor devices include forming insulating spacers on the sidewalls of a protruding portion of a first insulation film; forming a second trench by removing exposed regions of the semiconductor substrate using the insulating spacers as an etch mask, and thus forming fins in contact with and supported by the first insulation film. After forming the fins, a third insulation film is formed to fill the second trench and support the fins. A portion of the first insulation film is then removed to open a space between the fins in which additional structures including gate dielectrics, gate electrodes and additional contact, insulating and storage node structures may be formed.

  • Publication number: 20080283879
    Abstract: A transistor having a gate dielectric layer of partial thickness difference and a method of fabricating the same are provided. The method includes forming a gate dielectric layer having a main portion with a relatively thin thickness formed on a semiconductor substrate, and a sidewall portion with a relatively thick thickness formed on both sides of the main portion. A first gate is formed overlapping the main portion of the gate dielectric layer, and forming a second gate layer covering the sidewall portion of the gate dielectric layer and covering the first gate. The second gate layer is etched, thereby forming second gates patterned with a spacer shape on sidewalls of the first gate. The exposed sidewall portion of the gate dielectric layer is selectively etched using the second gates as a mask, thereby forming a pattern of the gate dielectric layer to be aligned with the second gates. A source/drain is formed in a portion of the semiconductor substrate exposed by the second gates.

  • Publication number: 20080239172
    Abstract: Disclosed is a table type bi-directional imaging apparatus, in which left and right viewers located at left and right sides simultaneously view the same picture or different pictures. The table type bi-directional imaging apparatus includes a table case having a table shape; a transparent window formed through the center of the upper surface of the table case; and left and right projectors and left and right imaging plates, having a screen structure, bilaterally symmetrically installed at left and right sides of the inside of the table case. In the table type bi-directional imaging apparatus, left and right projection distances to project pictures on large-sized screens and left and right viewing distances to view clear pictures are provided within an occupation area of a single table. Further, the imaging apparatus has a table structure, and thus does not require the occupation area of a separate table, thereby minimizing an area for installing the imaging apparatus.

  • Patent number: 7425275
    Abstract: A method of fabricating a vertically tapered structure. The method includes placing a spacer layer at a predetermined area on a wafer, placing a mask layer at a predetermined area on the spacer layer, and over-etching the spacer layer, by etching a certain area below the mask layer, fabricating a cantilever type shadow mask having the spacer layer and the mask layer. Thus, it is possible to fabricate the vertically tapered structure of several tens of microns. The vertically tapered structure can be used as the optical waveguide in the optical device to minimize junction loss that may occur between the optical waveguide and the optical fiber.
