STRESS MITIGATION STRUCTURE FOR WAFER WARPAGE REDUCTION |
摘要 |
An integrated circuit device includes a substrate. The integrated circuit device also includes a first conductive stack including a back-end-of-line (BEOL) conductive layer at a first elevation with reference to the substrate. The integrated circuit device also includes a second conductive stack including the BEOL conductive layer at a second elevation with reference to the substrate. The second elevation differs from the first elevation. |
