  • Publication number: 20130130415
    Abstract: Methods of fabricating integrated circuit devices utilize fuse elements to support sequential testing of vertically-integrated test elements during fabrication. These methods include forming a first test element, a first fuse and a first test pad electrically connected by the first fuse to the first test element, on a substrate. The first test element is tested by passing a first current between the first test element and first test pad and through the first fuse. The first fuse is then “cut” by increasing an impedance of the first fuse, which may include breaking the first fuse to create an electrical “open” (infinite impedance) or greatly increasing a resistance of the first fuse (e.g., by narrowing the fuse through electromigration). A second test element and a second test pad, which is electrically connected to the second test element and the first test pad, are then formed on the substrate.

  • Patent number: 7927289
    Abstract: Disclosed is a catheter used to pick a sample of a lesion cell tissue existing in the living body, and more particularly a catheter capable of freely coupling or separating a micro biopsy tool and picking a tissue required for an examination just by inserting and extracting the biopsy tool into and from a lesion region when picking the tissue. The catheter can pick a tissue required to diagnose and treat an examinee with a minimal invasion. Accordingly, it is possible to alleviate the examinee's pain and to prevent a perforation from occurring in the picked region when picking the tissue. In addition, according to the catheter of the invention, since the micro biopsy tool can be easily mounted and separated, the catheter can be semi-permanently used by continuously replacing the biopsy tool only.

  • Patent number: 7888772
    Abstract: A semiconductor device includes a fuse transistor for fuse programming and a fuse block connected to the fuse transistor, wherein the fuse block comprises a fuse line and a heat spreading structure connected to the fuse line. The electrical fuse employs the heat spreading structure connected to the fuse line to prevent a rupture of the electrical fuse such that heat, which is generated in the fuse line during a blowing of the fuse line, is spread throughout the heat spreading structure. Thus, a sensing margin of the electrical fuse can be secured and a deterioration of devices adjacent to the electrical fuse by heat generated in the electrical fuse can be prevented.
