In a method of forming a chalcogenide compound target, a first powder including germanium carbide or germanium is prepared, and a second powder including antimony carbide or antimony is prepared. A third powder including tellurium carbide or tellurium is prepared. A powder mixture is formed by mixing the first to the third powders. After a shaped is formed body by molding the powder mixture. The chalcogenide compound target is obtained by sintering the powder mixture. The chalcogenide compound target may include a chalcogenide compound that contains carbon and metal, or carbon, metal and nitrogen considering contents of carbon, metal and nitrogen, so that a phase-change material layer formed using the chalcogenide compound target may stable phase transition, enhanced crystallized temperature and increased resistance. A phase-change memory device including the phase-change material layer may have reduced set resistance and driving current while improving durability and sensing margin.

An LCD is fabricated using a diffraction mask with transmissive, semi-transmissive, and opaque regions. The semi-transmissive region permits formation of a transmission, reflection, or pixel electrode, depending on the type of LCD being fabricated, using the same masking process as that to produce contact holes in an insulating film and a conductive layer. Photoresist exposed through the semi-transmissive region is partially removed during developing that completely removes photoresist in the transmissive or opaque region. The contact holes are formed in the region in which the photoresist is completely removed, the photoresist and underlying conductive layer in the semi-transmissive region are then removed, and the remaining photoresist is stripped.

An image sensor with a high dynamic range is provided. The image sensor includes a semiconductor substrate, a plurality of light-receiving elements formed on the semiconductor substrate, and light-shield films formed on upper ends of some of the light-receiving elements to partially block light incident upon each of the some light-receiving elements. Hence, an image sensing device including the image sensor can detect an accurate image regardless of whether the environment is bright or dark.

An organic light-emitting diode display (OELD) device is presented that reduces the number of outputs of a data driver. The OELD device includes data and scan lines which cross each other. Pixel cells that contain organic electro-luminescence diodes are arranged in a matrix in pixel areas between the data lines and the scan lines. The pixel cells are arranged in different colors in a vertical direction and in the same color in a horizontal direction. A data driver supplies data to the data lines. A scan driver supplies a scan signal to the scan lines.

Disclosed are a copper wire or a copper electrode protected by a silver thin layer coated on a surface of the copper wire or the copper electrode, and a method for fabricating the copper wire or the copper electrode. A liquid crystal display device and a method for manufacturing the same are also disclosed. After forming the copper wire or the copper electrode on the substrate, a silver thin layer is coated on the surface of the copper wire or the copper electrode, so that the silver thin layer protects copper. Thus, the copper has superior resistance against oxidation reaction or other unnecessary reactions, thereby improving the performance of the copper wire or the copper electrode.
