20080289576 | Plasma based ion implantation system - A plasma based ion implantation system capable of generating a capacitively coupled plasma having beneficial characteristics for an ion implantation, including the generation of necessary ions and radicals only for an ion implantation process instead of generating an inductively coupled plasma, which generates unnecessary ions and excessively dissociates radicals. The plasma based ion implantation system easily controls plasma ions implanted by cleaning a vacuum chamber, minimizes problems of unnecessary deposition and occurrence of contaminants and increases the number of components used only for the plasma ion implantion by reducing the deposition of polymer layer on a workpiece. The plasma based ion implantation system easily control uniformity of the plasma by using a flat type electrode, thereby easily ensuring uniformity of plasma ions implanted into the workpiece. | 11-27-2008 |
20090026383 | X-Ray Detector and Method of Manufacturing the Same - Disclosed is an X-ray detector and a method of manufacturing the X-ray detector. A cushion layer is interposed between a scintillator panel for converting X-rays into visual light and a lower substrate formed with a thin film transistor, a photoelectric conversion device. Thus, the lower substrate and the scintillator panel can be bonded to each other such that no air layer can be introduced between the lower substrate and the scintillator panel. Therefore, no air layer is introduced, and thus, it is possible to prevent the efficiency of light incident to the photoelectric conversion device from being lowered. Further, the cushion layer is employed such that the lower substrate and the scintillator panel can be separated and reused. | 01-29-2009 |
