    Abstract: Various embodiments of the present disclosure are directed towards an image sensor. The image sensor comprises a plurality of photodetectors disposed within a substrate. A metal grid layer is disposed over the substrate. The metal grid layer comprises a metal grid structure overlying a central pixel region of the substrate. The metal grid layer continuously extends from the central pixel region to a peripheral pixel region of the substrate that laterally encloses the central pixel region. An upper metal structure is disposed over the metal grid layer. The upper metal structure overlies the peripheral pixel region. The upper metal structure is laterally offset from the metal grid structure. A lower surface of the upper metal structure is disposed vertically over an upper surface of the metal grid structure.

    Abstract: The present disclosure relates to an integrated chip comprising a substrate having a first top surface disposed at a first height, a second top surface disposed at a second height that is less than the first height, and a connecting surface extending from the first top surface to the second top surface. A first source/drain region is disposed along the first top surface of the substrate. A second source/drain region is disposed along the second top surface of the substrate and is laterally separated from the first source/drain region by a channel region of the substrate. A gate structure is arranged between the first source/drain region and the second source/drain region. The gate structure extends from over the first top surface of the substrate to over the connecting surface of the substrate. The gate structure also extends below the first top surface of the substrate.

    Abstract: The present disclosure relates to a resistive random access memory (RRAM) device architecture, that includes a thin single layer of a conductive etch-stop layer between a lower metal interconnect and a bottom electrode of an RRAM cell. The conductive etch-stop layer provides simplicity in structure and the etch-selectivity of this layer provides protection to the underlying layers. The conductive etch stop layer can be etched using a dry or wet etch to land on the lower metal interconnect. In instances where the lower metal interconnect is copper, etching the conductive etch stop layer to expose the copper does not produce as much non-volatile copper etching by-products as in traditional methods. Compared to traditional methods, some embodiments of the disclosed techniques reduce the number of mask step and also reduce chemical mechanical polishing during the formation of the bottom electrode.
