  • Patent number: 9190239
    Abstract: Disclosed is an apparatus and method for low-temperature plasma immersion processing of a variety of workpieces using accelerated ions, wherein low-temperature plasma is distributed around a cylindrical workpiece placed in a chamber, the workpiece is enclosed with a housing including a multi-slot extracting electrode to isolate the workpiece from plasma, and a negative potential sufficient to induce sputtering is applied to the workpiece and the electrode, so that ions from plasma are accelerated within the sheath formed between the extracting electrode and plasma, pass through the slot part of the electrode and bombard the workpiece, thus polishing the surface of the workpiece. This apparatus and method is effective for surface smoothing to ones of nm of large cylindrical substrates particularly substrates for micro or nanopattern transfer.
    Type: Grant

  • Patent number: 8964167
    Abstract: The present invention provides a cylindrical magnetic levitation stage and an exposure apparatus, which can form a nanoscale pattern of a large area directly on the surface of a large cylinder. The present invention provides an exposure apparatus including a new type of cylindrical magnetic levitation stage, which can levitate, rotate, and move a cylinder in the axial direction by the principle of magnetic levitation in a non-contact manner and form a nanoscale pattern on the surface of the cylinder, and a light source for irradiating light on the surface of the cylinder, thereby reducing the position error of the cylindrical magnetic levitation stage to a nanoscale size and correcting the error caused by mechanical processing in real time.
