Abstract:
1. A semiconductor device which has semiconductor elements, a wiring layer, and a plurality of interlayer insulating film layers on a semiconductor substrate, wherein a seal ring which encloses a semiconductor element region is formed with a damascene wiring structure using conductor material which forms the wiring layer, said seal ring having a first side and a second side, said first side being nearer than said second side to the semiconductor element region, and an isolated pocket group having a plurality of first and second isolated pockets of insulating material arranged in designated regions of the seal ring, said plurality of first isolated pockets constituting a first row of said isolated pocket group near said first side of said seal ring and said plurality of second isolated pockets constituting a second row of said isolated pocket group near said second side of said seal ring, wherein said plurality of first and second isolated pockets are arranged in a zigzag pattern along said first and second sides of said seal ring adjacent the semiconductor element region, and a shortest distance between said first side of said seal ring and said first row of said isolated pocket group is smaller than a shortest distance between said second side of said seal ring and said second row of said isolated pocket group.
