  • 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.

  • Patent number: 8354908
    Abstract: The present invention provides a cylindrical magnetic levitation stage which includes a cylindrical substrate used to form micro-patterns of various arbitrary shapes on a large-area semiconductor substrate or display panel substrate, a cylindrical substrate, a combination of a first permanent magnet array and a first coil array and a combination of a first permanent magnet array and a first coil array, which are coupled to the cylindrical substrate, so that levitation, axial translation and rotation of the cylindrical substrate can be made finely through the control of a magnetic force generated by the interaction between a magnetic field generated by electric current applied to the coil arrays and a magnetic field generated from the permanent magnet arrays corresponding to the coil arrays.

  • Publication number: 20110253674
    Abstract: The present invention relates to an inductively coupled plasma processing chamber and method for a cylindrical workpiece with a three-dimensional profile, and more particularly to an inductively coupled plasma processing reactor and method for a cylindrical workpiece with a three-dimensional profile, in which the workpiece serving as an internal RF antenna is connected to an RF power source through an impedance matching network at one end, and a terminating capacitor at another end so as to achieve low plasma contamination, confine dense uniform plasma in the substrate vicinity and suppress secondary electrons emitted from the substrate, and a plasma process can be applied to a 3-D linear semiconductor device, a metal, glass, ceramic or polymer substrate having planar or 3-D structured micro or nano patterns, and the like.
