Zusammenfassung:An interconnect structure and methods of forming the same are described. In some embodiments, the structure includes a first dielectric layer disposed over one or more devices, a first conductive feature disposed in the first dielectric layer, a second conductive feature disposed in the first dielectric layer, an etch stop layer disposed on the first dielectric layer, a second dielectric layer disposed on the etch stop layer, and a third conductive feature disposed in the second dielectric layer and the etch stop layer. The third conductive feature includes a first conductive layer, which includes a two-dimensional material. The structure further includes a fourth conductive feature disposed in the second dielectric layer and the etch stop layer. The third conductive feature and the fourth conductive feature include different number of layers.
