Patent ID: 8269333

Claim:
A zipper structure for power distribution in a semiconductor device, comprising: a first contiguous full-dense-mesh (FDM) array of a first supply in a top metal layer of a plurality of metal layers; a second contiguous FDM array of a second supply in a top-1 metal layer of the plurality of metal layers, wherein a portion of the first contiguous FDM array and a portion of the second contiguous FDM array overlap; a third contiguous FDM array of the second supply in the top metal layer; a fourth contiguous FDM array of the first supply in the top-1 metal layer, wherein a portion of the third contiguous FDM array and a portion of the fourth contiguous FDM array overlap; and a signal line, wherein the first contiguous FDM array is connected to the fourth contiguous FDM array by a first plurality of vias and a first plurality of connector lines in a recessed-square structure, wherein the second contiguous FDM array is connected to the third contiguous FDM array by a second plurality of vias and a second plurality of connector lines in a recessed-square structure, and wherein a portion of the signal line overlaps with a portion of the first plurality of connector lines and with a portion of the second plurality of connector lines.
