  • Publication number: 20050167824
    Abstract: A method of manufacturing an integrated circuit provides a substrate having a semiconductor device, and includes forming an intermetal dielectric layer over the substrate and the semiconductor device. A metal wire is formed above the semiconductor device and in contact therewith and a passivation layer is formed over the intermetal dielectric layer. A bond pad is formed connected to the metal wire. A protective moat, with sidewall passivation layer, is formed through the passivation layer and the intermetal dielectric layer, and is located between the metal wire and an outside edge of the integrated circuit.

  • Publication number: 20050127495
    Abstract: In accordance with the objectives of the invention a new design and method for the implementation thereof is provided in the form of an “oxide ring”. A conventional die is provided with a guard ring or sealing ring, which surrounds and isolates the active surface area of an individual semiconductor die. The “oxide ring” of the invention surrounds the guard ring or sealing ring and forms in this manner a mechanical stress release buffer between the sawing paths of the die and the active surface area of the singulated individual semiconductor die.
