Abstract: Provided are a multi-gate MOS transistor and a method of manufacturing the same. Two silicon fins are vertically stacked on a silicon on insulator (SOI) substrate, and four side surfaces of an upper silicon fin and three side surfaces of a lower silicon fin are used as a channel. Therefore, a channel width is increased, so that current driving capability of a device is improved, and high performance nano-level semiconductor IC and highly integrated memory IC can be manufactured through the optimization and stability of a process.

Abstract: The present invention relates to a method of searching for a recordable position of a writable disk, the method comprising the steps of (a) reading data recording information of the writable disk, the data recording information indicating a position of a last track recorded and a recordable position for data to be recorded; (b) examining whether or not an area after the recordable position indicated by the read data recording information has recorded data; and (c) determining whether to change the recordable position to another position for new input data based on the examination result.

Abstract: Provided is a source driver circuit for an active matrix electroluminescent (EL) display including a digital-to-analog converter/ramp circuit for converting a digital signal into an analog signal, and generating a ramp signal in this process, simultaneously, whereby high degree of integration would be possible since a conventional complicated circuit is not required and gray scale with the high characteristic can be implanted, regardless of a change of a temperature or a threshold voltage.

Abstract: An optical recording medium and method for recording/reproducing data on/from the optical recording medium having an optimum recording condition information, are provided. The method includes reading out a reference recording condition recorded on a specific area of the optical recording medium; recording test data while varying a recording condition with respect to the reference recording condition; determining an optimum recording power based on reproduction characteristics of the test data; and recording a recoding condition data including the optimum recording power, recording speed and write strategy type to be used or used to record data, on a specific area of the optical recording medium.

Abstract: A method and apparatus for optimally recording data on an optical recording medium by controlling recording beam power depending upon the state of the recording layer of the recording medium. To compensate for variant reflection ratio at inner and outer radius caused by the uneven recording layer thickness, the power of recording beam is adjusted and as a result the asymmetric ratio is maintained constant over the recording medium without regard to the radius. A signal associated with the recording layer thickness variation is detected and the recording beam power is adjusted to compensate for the variation of the characteristic of recorded marks, based upon the signal. The adjusted recording beam power is not readjusted by the running optimal power control (ROPC). The method in accordance with the present invention provides a constant asymmetric ratio over the recording medium, thereby reducing the likelihood of reproduced data error.
