Patent ID: 8907497

Claim:
A device comprising: a first interlayer dielectric (ILD) layer disposed over a substrate, the first ILD layer including a first conductive layer including first and second conductive lines in a first direction; and a second ILD layer disposed over the first ILD layer, the second ILD layer including a second conductive layer including first and second conductive lines in a second direction, wherein the first conductive line of the second conductive layer is formed over the first conductive line of the first conductive layer and contacts the first conductive line of the first conductive layer at an interface, the interface providing electrical contact without the use of a via, wherein the second conductive line of the second conductive layer is formed over the second conductive line of the first conductive layer, and wherein a blocking portion is interposed between the second conductive line of the second conductive layer and the second conductive line of the first conductive layer.
