  • Patent number: 11973050
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip. The integrated chip includes an interconnect structure overlying a semiconductor substrate and comprising a conductive wire. A passivation structure overlies the interconnect structure. An upper conductive structure overlies the passivation structure and comprises a first conductive layer, a dielectric layer, and a second conductive layer. The first conductive layer is disposed between the dielectric layer and the passivation structure. The second conductive layer extends along a top surface of the dielectric layer and penetrates through the first conductive layer and the passivation structure to the conductive wire.

  • Publication number: 20230363178
    Abstract: 1. Various embodiments of the present disclosure are directed towards a ferroelectric random-access memory (FeRAM) cell or some other suitable type of memory cell comprising a bottom-electrode interface structure. The memory cell further comprises a bottom electrode, a switching layer over the bottom electrode, and a top electrode over the switching layer. The bottom-electrode interface structure separates the bottom electrode and the switching layer from each other. Further, the interface structure is dielectric and is configured to block or otherwise resist metal atoms and/or impurities in the bottom electrode from diffusing to the switching layer. By blocking or otherwise resisting such diffusion, leakage current may be decreased. Further, endurance of the memory cell may be increased.
