Claim 0:
1. A semiconductor structure having a conductive structure, comprising:
a first conductive line and a second conductive line, located in a first dielectric layer and laterally extending along a first direction, wherein the first conductive line and the second conductive line are spaced from each other by the first dielectric layer therebetween;
a third conductive line, located in a second dielectric layer and laterally extending along a second direction different form the first direction; and
a conductive via, located in a third dielectric layer, extending laterally between the first and second conductive lines, extending vertically between the first conductive line and the third conductive line, and extending vertically between the second conductive line and the third conductive line,
wherein the third dielectric layer is separated from the second dielectric layer by an etching stop layer located there-between,
wherein the lateral dimension of the conductive via in the first direction is less than the lateral dimension of the third conductive line in the first direction, and the lateral dimension of the first conductive line in the first direction is larger than the lateral dimension of the third conductive line in the first direction,
wherein the lateral dimension of the third conductive line in the second direction is greater than the lateral dimension of the conductive via in the second direction, and the lateral dimension of the conductive via in the second direction is larger than the lateral dimension of the first conductive line in the second direction,
and wherein the conductive via, in a vertical direction, is overlapped with a portion of the first dielectric layer that is laterally between the first conductive line and the second conductive line, and the conductive via is in direct contact with the first, second, and third conductive lines.
