SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

There is provided a semiconductor device, comprising a substrate (101) that includes an integrated circuit region (1), first and second interlayer insulation films (108, 111, 112) formed above the substrate, and a reinforcing structure comprising a main-wall part (2) and a sub-wall part (3) which are formed in the first and second interlayer insulation films, wherein the main-wall part surrounds the integrated circuit region in a periphery thereof and the sub-wall part is provided apart from the main-wall part in a corner region of the semiconductor device and is located between the integrated circuit region and the first bend section of the main-wall part. Both the main-wall part and the sub-wall part are formed by metal-filled trenches (131, 132) in the first and second interlayer insulation films.
