Publication number: 20240145381Abstract: In some embodiments, the present disclosure relates an integrated chip including a substrate. A conductive interconnect feature is arranged over the substrate. The conductive interconnect feature has a base feature portion with a base feature width and an upper feature portion with an upper feature width. The upper feature width is narrower than the base feature width such that the conductive interconnect feature has tapered outer feature sidewalls. An interconnect via is arranged over the conductive interconnect feature. The interconnect via has a base via portion with a base via width and an upper via portion with an upper via width. The upper via width is wider than the base via width such that the interconnect via has tapered outer via sidewalls.Type: ApplicationFiled: January 9, 2024Publication date: May 2, 2024Inventors: Shin-Yi Yang, Hsin-Yen Huang, Ming-Han Lee, Shau-Lin Shue, Yu-Chen Chan, Meng-Pei Lu
