    摘要: Example embodiments may provide fine patterns for semiconductor devices and methods of forming fine patterns for semiconductor devices. Example methods may include forming a spacer pattern on a substrate and/or an insulating layer pattern adjacent to sides of the spacer pattern and/or disposed at the same level as the spacer pattern, forming a pair of recesses exposing sides of the spacer pattern by removing a portion of the insulating layer pattern, and/or filling a conductive material in the recesses.

    摘要: A fuse area structure in a semiconductor device and a method of forming the same are provided. A ring-shaped guard ring which surrounds a fuse opening, for preventing moisture from seeping into the side surface of the exposed fuse opening, is included. The guard ring is integrally formed with a passivation film. In order to form the guard ring, a guard ring opening etching stop film is formed on a fuse line. A guard ring opening is formed using the etching stop film, and a contact hole is formed in a peripheral circuit. A conductive material layer for forming an upper interconnection layer is formed on the entire surface of a resultant structure on which the contact hole and the guard ring opening are formed. The conductive material layer formed on the guard ring opening is removed. The exposed etching stop film is removed. Finally, a passivation film is deposited on the entire surface of the resulting structure. Accordingly, the guard ring formed of the passivation film filling the guard ring opening is formed. It is possible to form the guard ring without an additional process, to thus effectively prevent moisture from seeping into interfaces between interlayer dielectric films. Also, an additional photolithography process for forming the guard ring is not necessary since the guard ring opening and the contact hole in the peripheral circuit are simultaneously formed.
