Abstract:
A method for manufacturing a scribe seal, comprising:providing a substrate having a major surface; disposing a first layer of dielectric material on a portion of the major surface; forming a first opening in the first layer of dielectric material; filling the first opening with a crack arresting material; disposing a second layer of dielectric material on the crack arresting material and the first layer of dielectric material; forming a second opening in the second layer of dielectric material by forming a via extending into the second layer of dielectric material and forming a trench via extending into the second layer of dielectric material wherein the via and the trench via cooperate to form the second opening, wherein the second opening is laterally spaced apart from the first opening and exposing a portion of the first layer of dielectric material; and filling the second opening with the crack arresting material.
