摘要:
A semiconductor device has a singulated die having a substrate and a die edge. An interconnect dielectric layer is located on the substrate, and integrated circuit has interconnections located within the interconnect dielectric layer. A trench is located in the interconnect dielectric layer and between a seal ring and a remnant of the interconnect dielectric layer. The seal ring is located within the interconnect dielectric layer and between the trench and the integrated circuit, with the remnant of the interconnect dielectric layer being located between the trench and the edge of the die.
