  • Publication number: 20060279598
    Abstract: The nozzle error correction method is provided for adjusting information of an output image to correct an error nozzle. A position of an error nozzle firing an ink amount different from a reference value is detected from a plurality of nozzles. A determination is made from an input image as to whether a current pixel for output is an error pixel of the detected error nozzle. A channel value of the error nozzle is set to a certain value if the current pixel is the error pixel. However, if the current pixel is not the error pixel, a determination is made as to whether an error pixel exists in a certain area around the current pixel. A value of the current pixel is then adjusted based on error information. Image-processing is performed in order for the current pixel to be outputted, if the error pixel exists in the certain area. Accordingly, degradation of a print speed and a shortened life span of the head are prevented.

  • Publication number: 20060113580
    Abstract: In a capacitor having a high dielectric constant, the capacitor includes a cylindrical lower electrode, a dielectric layer and an upper electrode. A metal oxide layer is formed on inner, top and outer surfaces of the lower electrode as the dielectric layer. A first sub-electrode is formed on a surface of the dielectric layer along the profile of the lower electrode and a second sub-electrode is continuously formed on the first sub-electrode corresponding to the top surface of the lower electrode, so an opening portion of the lower electrode is covered with the second sub-electrode. The first and second sub-electrodes include first and second metal nitride layers in which first and second stresses are applied, respectively. Directions of the first and second stresses are opposite to each other. Accordingly, cracking is minimized in the upper electrode with the high dielectric constant, thereby reducing current leakage.

  • Publication number: 20060115946
    Abstract: In an embodiment, a method of forming a lower electrode of a capacitor in a semiconductor memory device includes etching a mold oxide layer to have at a cylindrical structure, resulting in an electrode with increased surface area. The cylindrical structure may have more than one radius. This increased surface area results in an increased capacitance. An excessive etch phenomenon, which occurs because a sacrificial oxide layer is etched at a higher rate than the mold oxide layer, is avoided.
