  • Patent number: 7777338
    Abstract: A seal ring structure is disclosed for protecting a core circuit region of an integrated circuit chip. The seal ring structure includes a metallization layer, having a bridge sublevel and a plug sublevel. An upper-level bridge is formed on the bridge sublevel at a predetermined location between a peripheral edge of the integrated circuit chip and the core circuit region. A lower-level bridge is formed on the plug sublevel in substantial alignment with the upper-level bridge, wherein the lower-level bridge has a width substantially the same as that of the upper-level bridge.

  • Publication number: 20060055002
    Abstract: A wafer device is disclosed for improving reliability of circuits fabricated in an active area on a silicon substrate. A seal ring is fabricated around the active area, and a shallow trench isolation is also formed between the seal ring and a scribe line by etching into a portion of the silicon substrate, wherein the seal ring and the shallow trench isolation prevent die saw induced crack from propagating to the active area when the active area is cut along the scribe line.
