  • Patent number: 6835998
    Abstract: A fuse area structure in a semiconductor device and a method of forming the same are provided. The fuse area structure includes a protection film formed of a passivation film for preventing moisture from seeping into the sidewall of an exposed fuse opening. In order to form the protection film, an etching stop film is formed on a fuse line, and the fuse opening is formed at the same time using the etching stop film when a contact hole required for the semiconductor device is formed. 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 fuse opening are formed. The conductive material layer formed on the fuse opening is removed. The exposed etching stop film is removed. Finally, the fuse area is completed by forming a passivation film on the entire surface of the resultant structure and removing the passivation film formed on the bottom of the fuse opening into which laser is to be irradiated.
