20090127102 | PLASMA DEPOSITION APPARATUS AND METHOD - A plasma deposition apparatus includes a cathode assembly including a cathode disk and a water-coolable cathode holder supporting the cathode disk, an anode assembly including a water-coolable anode holder, a substrate mounted on the anode holder to serve as an anode, and a substrate holder mounting and supporting the substrate, and a reactor for applying a potential difference between opposing surfaces of the cathode assembly and the anode assembly under a vacuum state to form plasma of a raw gas. The cathode disk comes into thermal contact with the cathode holder using at least one of a self weight and a vacuum absorption force so as to permit thermal expansion of the cathode disk. | 05-21-2009 |
20090168504 | Phase change memory apparatus having an improved cycling endurance and programing method therefor - A phase change memory apparatus includes a phase change memory array in which a plurality of phase change memory devices are arranged, and a pulse generator that supplies a writing current pulse, an erasure current pulse, and a reverse repair current pulse to the phase change memory devices in the phase change memory array. The reverse repair current pulse has opposite direction to the writing current pulse and the erasure current pulse of the phase change memory devices, and is of such a size that resultant Joule heat and electromigration move the elements of the reverse repair current pulse. The reverse repair current pulse has a width equal to or more than a smaller one of duration of a normal writing operation and duration of a normal erasure operation. | 07-02-2009 |
20090245079 | OPTICAL RECORDING MEDIUM HAVING SUPER-RESOLUTION STRUCTURE FOR IMPROVEMENT OF REPRODUCING STABILITY AND NOISE CHARACTERISTIC IN LOW FREQUENCY BAND - A super-resolution optical recording medium includes a reflective layer formed on a substrate, a recording layer for recording information thereon, a super-resolution layer made of a chalcogenide semiconductor material, and a first and a second dielectric layers laminated on upper and lower surfaces of the super-resolution layer. The recording layer is made of a material that has a decomposition temperature higher than an information reproduction temperature and does not form bubble recording marks during recording, and the super-resolution layer contains one or more elements selected from the group consisting of nitrogen, oxygen, carbon, and boron. | 10-01-2009 |
20090324824 | METHOD FOR GROWING THIN FILM - Disclosed is a method for growing a thin film, which includes modifying a surface grain size and surface roughness on a thin film to improve the mobility of a carrier and a light scattering effect. The method for growing a thin film includes: forming nuclei of grains having various grain orientations on a substrate; causing first grains having a first specific grain orientation to grow predominantly among the grains having various grain orientations, thereby forming a first preferred texture comprised of the predominantly grown first grains; and then causing second grains having a second grain orientation to grow predominantly, thereby forming a second preferred texture comprised of the predominantly grown second grains, wherein the surface grain size of each of the second grains forming the second texture is larger than that of each of the first grains forming the first texture. | 12-31-2009 |
20100065892 | Bio-sensor and method of manufacturing the same - A bio-sensor includes a gate dielectric formed on a silicon semiconductor substrate, a gate electrode of a conductive diamond film formed on the gate dielectric, probe molecules bonded on the gate electrode for detecting biomolecules, and source/drain regions formed on the semiconductor substrate at the sides of the gate electrode. The gate electrode is a comb shape or a lattice shape. | 03-18-2010 |
