Abstract:
A semiconductor die includes a plurality of layers, the plurality of layers having a top surface. A scribe seal is located in the plurality of layers and includes a first metal stack having a first metal layer located proximate the top surface. A trench is located in at least one layer of the plurality of layers. The trench extends from the top surface of the plurality of layers and is located a distance from the first metal stack. An electrical insulating layer is located on the top surface. The electrical insulating layer covers at least a portion of the top surface adjacent the first metal layer and extends a distance from the top surface of the first metal layer.
