Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate including:
a chip region; and
a scribe lane region surrounding the chip region, the scribe lane region having first edges opposite to each other and second edges opposite to each other, each of the first edges extending in a first direction and each of the second edges extending in a second direction crossing the first direction;

a first insulating interlayer structure on the scribe lane region of the substrate, the first insulating interlayer structure including a low-k dielectric material;
first conductive structures on a portion of the scribe lane region of the substrate adjacent to one of the first edges, each of the first conductive structures extending through the first insulating interlayer structure in a vertical direction substantially perpendicular to an upper surface of the substrate and extending in the first direction;
a second insulating interlayer on the first insulating interlayer structure, the second insulating interlayer including a material having a dielectric constant greater than that of the first insulating interlayer structure;
first vias on the scribe lane region of the substrate, each of the first vias extending in the first direction through the second insulating interlayer and at least a portion of the first insulating interlayer structure to contact one of the first conductive structures, and each of the first vias directly contacting the portion of the first insulating interlayer structure; and
a first wiring commonly contacting upper surfaces of the first vias,
wherein each of the first conductive structures includes second wirings and second vias alternately and repeatedly stacked in the vertical direction, and an uppermost one of the second wirings contacts a corresponding one of the first vias, and
wherein the second wirings on the respective second vias at a same level do not contact each other.
