Patent ID: 8896089

Claim:
An interposer, comprising: a substrate; a contact pad disposed on a first side of the substrate; a first through-via in the substrate having a first end terminating on and directly contacting the contact pad; a first fuse on a second side of the substrate opposite the first side and coupled to the first through-via; a second through-via in the substrate having a first end terminating on and directly contacting the contact pad; and a second fuse on the second side of the substrate and coupled to the second through-via; the first fuse is connected between a first connecting region and a second connecting region, and the first connecting region, the second connecting region and the first fuse are embedded in an insulating material layer on the substrate wherein a width of the first connecting region, the second connecting region and the first fuse is different from each other in a planar view; and the second fuse is connected between a third connecting portion and a fourth connecting portion, and the third connecting portion, the fourth connecting portion and the second fuse are embedded in the insulating material layer on the substrate wherein a width of the third connecting portion, the fourth connecting portion and the second fuse is different from each other in the planar view.
