Abstract: A method for manufacturing a semiconductor device is provided. A first gate can be formed in a salicide region of a semiconductor substrate, and a second gate can be formed in a non-salicide region of the semiconductor substrate. A source and a drain can be formed at both sides of each of the first and second gates. An insulating layer covering the first and second gates can be formed, and first and second spacers can be formed on the insulating layer. The non-salicide region can be covered with a mask, and the insulating layer of the salicide region can be selectively removed. Salicide can then be formed on the first gate, and the source and drain of the first gate.

Abstract: A method of fabricating a semiconductor device is provided. Spacers can be formed on adjacent gate structures and used as an ion implantation mask for forming source/drain regions. The spacers can include a nitride layer and an oxide layer. An etch stop layer can be provided between the gate structures, and the oxide layer can be removed from the spacers. A first oxide layer formed below the nitride layer can be protected from being etched away during removal of the oxide layer from the spacers by the etch stop layer. The etch stop layer and the first oxide layer can be removed, and an interlayer dielectric layer can be deposited.

Abstract: Embodiments relate to an image sensor and a method for manufacturing an image sensor. According to embodiments, a transistor structure may be manufactured on a semiconductor substrate, and an insulating layer covering the transistor structure may be formed. The insulating layer may be patterned to form a first via that may expose the semiconductor substrate, and a silicon layer may be formed on the first via and the insulating layer. The silicon layer and the insulating layer may be patterned to form a second via exposing the transistor structure, and the second via may be filled with metal to form a connecting line electrically connected with the transistor structure. Conductive impurities may be implanted into the silicon layer and may form a light receiving portion connected with the connecting line.

Abstract: A method of forming a dual damascene pattern for a metal interconnection by a relatively simple process. Only a portion of an interlayer insulating film is initially etched when forming a via hole. When the interlayer insulating is etched to form a trench, the remaining portion of the via hole may be etched simultaneously.

Abstract: A thieno[3,2-b]indole-based polymer and an organo-electroluminescent device in which the polymer is introduced into an organic layer are provided. The thieno[3,2-b]indole-based polymer may be easily prepared and has blue light-emitting characteristic. The organo-electroluminescent device adopting the organic layer using the thieno[3,2-b]indole-based polymer has improved color purity, efficiency, and luminance characteristics.
