  • Patent number: 8906763
    Abstract: A DRAM device includes a substrate including an active region having an island shape and a buried gate pattern. A mask pattern is over an upper surface portion of the substrate between portions of the buried gate pattern. A capping insulating layer fills a gap between portions of the mask pattern. A first pad contact penetrates the capping insulating layer and the mask pattern, and contacts a first portion of the substrate in the active region. Second pad contacts are under the capping insulating layer, and contact a second portion of the substrate in the active region positioned at both sides of the first pad contact. A spacer is between the first and second pad contacts to insulate the first and second pad contacts. A bit line configured to electrically connect with the first pad contact, and a capacitor configured to electrically connect with the second pad contacts, are provided.

  • Publication number: 20140357045
    Abstract: An improved eFuse and method of fabrication is disclosed. A cavity is formed in a substrate, which results in a polysilicon line having an increased depth in the area of the fuse, while having a reduced depth in areas outside of the fuse. The increased depth reduces the chance of the polysilicon line entering the fully silicided state. The cavity may be formed with a wet or dry etch.

  • Publication number: 20140339675
    Abstract: A polysilicon fuse is disclosed that is capable of securing good insulation after being cut into small areas. A manufacturing method for the fuse and a small-size and highly-reliable semiconductor device including a polysilicon fuse also are disclosed. By forming a cavity inside a polysilicon portion serving as a melting portion by setting the melting portion of the polysilicon fuse to be a vertical type, a gap is formed between an upper part electrode and the surface of melted polysilicon when the polysilicon fuse is cut off. Because of this gap, good insulation can be secured. By using this polysilicon fuse, a semiconductor device that has a small size and high reliability is provided.
