  • Publication number: 20230400673
    Abstract: The present invention relates to a flying-over beam pattern scanning hologram microscope device using a spatial modulation scanner and a translation stage. The present invention provides a flying-over beam pattern scanning hologram microscope device comprising: a scan beam generation unit which converts of a first beam and a second beam to a first spherical wave, and then makes the first and the second spherical waves interfere with each other to form a scan beam; a scanning unit, which comprises a spatial modulation scanner for controlling the scan beam in the horizontal direction, and a translation stage for moving an object in the vertical direction at the rear end of the projection unit; the projection unit projecting the scan beam onto an object plane; and a light collection unit which detects a beam that has passed through the objective lens again after being reflected or fluoresced from the object.

  • Patent number: 7375025
    Abstract: On first and second regions of a substrate are formed a first gate structure including a first gate electrode and a first spacer, and a second gate structure including a second gate electrode and a second spacer, respectively. The first and second spacers are removed to different depths such that side portions of the first and second gate electrodes have different exposed thicknesses. A metal silicide layer is formed on the first and second regions including the first and second gate structures. The metal silicide layer formed on the second gate electrode has a second thickness that is greater than a first thickness of the metal silicide layer formed on the first gate electrode. The spacers in the gate structures of resulting N type and P type MOS transistors are removed to different thicknesses, thereby minimizing deformation in the gate structures and also improving electrical characteristics and thermal stability of the gate electrodes.

  • Patent number: 7311109
    Abstract: A method for cleaning a processing chamber and manufacturing a semiconductor device by removing impurities from a substrate in the processing chamber with a plasma of a first gas including hydrogen gas. After the substrate is removed from the processing chamber, the processing chamber is etched with the plasma of a non-hydrogenous second gas. Thus, the etching selectivity can be improved and the particles are prevented from depositing and/or forming on the substrate.

  • Patent number: 6797618
    Abstract: A conductive pattern having a surface including silicon is formed on a substrate of a semiconductor device and a conduction region having a surface including silicon is formed in the substrate. A radio frequency etching process is performed ex-situ to remove impurities from a resultant structure and to improve surface characteristics of the conduction region. Residues generated during the radio frequency etching process are removed from the conductive pattern and the conduction region by a cleaning process. A metal film is formed on the conductive pattern and the conduction region. A silicide film is formed on the conductive pattern and the conduction region by reacting metal of the metal film and silicon in the conductive pattern and the conduction region. With a radio frequency sputtering process and a wet cleaning process, a metal silicide film having a uniform phase may be stably formed.

  • Patent number: 6355554
    Abstract: Methods of fabricating an interconnection to an underlying microelectronic layer include removing a portion of the insulation layer to form a plurality of contact holes having different contact sizes therethrough and thereby expose a portion of the microelectronic layer. A conductive material is deposited on the insulation layer and in the contact hole with a sufficient thickness such that a bridge is generated in the largest contact hole. The deposited conductive material is then reflowed to fill the contact hole and form an interconnection to the underlying microelectronic layer, by supplying a high pressure such that at least the void formed in the largest contact hole is filled. The conductive material may be planarized to thereby expose the insulation layer. The present invention may be applied to an asymmetrical contact hole, for example, a dual damascene structure.
