Abstract:
1. A method for forming a crack stop structure in a scribe line, comprising: providing a substrate comprising a scribe line region and a circuit region; forming an integrated circuit within said circuit region; forming a first layer embedded in said substrate, wherein said first layer is partially disposed within said scribe line region; forming an interlayer dielectric layer disposed on said substrate and covering said integrated circuit and said first layer; forming a second layer embedded in said interlayer dielectric layer, wherein said second layer is partially disposed within said scribe line region; forming an intermetal dielectric layer disposed on said interlayer dielectric layer and covering said second layer; removing said interlayer dielectric layer and said intermetal dielectric layer which are disposed within said scribe line region to form a crack stop trench, thereby partially exposing said first layer and said second layer; and filling said crack stop trench with a dielectric material to form a crack stop structure.
