摘要 |
An integrated circuit device includes a first metal layer including aluminum. The integrated circuit device includes a second metal layer including an interconnect structure. The interconnect structure includes a layer of first material including aluminum. The integrated circuit device includes an inter-diffusion layer that includes aluminum. The inter-diffusion layer is proximate to the first metal layer and proximate to the layer of first material including aluminum. The integrated circuit device includes a self-forming barrier layer that includes aluminum. The self-forming barrier layer is proximate to a dielectric layer and proximate to the layer of first material including aluminum. |

1. An integrated circuit device, comprising:
a first metal layer comprising aluminum; a second metal layer including an interconnect structure, wherein the interconnect structure includes a layer of first material including aluminum; an inter-diffusion layer including aluminum, the inter-diffusion layer proximate to the first metal layer and proximate to the layer of first material including aluminum; and a self-forming barrier layer including aluminum, the self-forming barrier layer proximate to a dielectric layer and the layer of first material including aluminum. |
