    Abstract: In some embodiments, the present disclosure relates to method of forming an integrated chip. The method includes forming a bottom electrode structure over one or more interconnect layers disposed within one or more stacked inter-level dielectric (ILD) layers over a substrate. The bottom electrode structure has an upper surface having a noble metal. A diffusion barrier film is formed over the bottom electrode structure. A data storage film is formed onto the diffusion barrier film, and a top electrode structure is over the data storage film. The top electrode structure, the data storage film, the diffusion barrier film, and the bottom electrode structure are patterned to define a memory device.

    Abstract: A sputtering system includes a vacuum chamber, a power source having a pole coupled to a backing plate for holding a sputtering target within the vacuum chamber, a pedestal for holding a substrate within the vacuum chamber, and a time of flight camera positioned to scan a surface of a target held to the backing plate. The time of flight camera may be used to obtain information relating to the topography of the target while the target is at sub-atmospheric pressure. The target information may be used to manage operation of the sputtering system. Managing operation of the sputtering system may include setting an adjustable parameter of a deposition process or deciding when to replace a sputtering target. Machine learning may be used to apply the time of flight camera data in managing the sputtering system operation.

    Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip. The method includes forming a plurality of bond pad structures over an interconnect structure on a front-side of a semiconductor body. The plurality of bond pad structures respectively have a titanium contact layer. The interconnect structure and the semiconductor body are patterned to define trenches extending into the semiconductor body. A dielectric fill material is formed within the trenches. The dielectric fill material is etched to expose the titanium contact layer prior to bonding the semiconductor body to a carrier substrate. The semiconductor body is thinned to expose the dielectric fill material along a back-side of the semiconductor body and to form a plurality of integrated chip die. The dielectric fill material is removed to separate the plurality of integrated chip die.

    Abstract: Various embodiments of the present application are directed towards a method for forming a metal-insulator-metal (MIM) capacitor comprising an enhanced interfacial layer to reduce breakdown failure. In some embodiments, a bottom electrode layer is deposited over a substrate. A native oxide layer is formed on a top surface of the bottom electrode layer and has a first adhesion strength with the top surface. A plasma treatment process is performed to replace the native oxide layer with an interfacial layer. The interfacial layer is conductive and has a second adhesion strength with the top surface of the bottom electrode layer, and the second adhesion strength is greater than the first adhesion strength. An insulator layer is deposited on the interfacial layer. A top electrode layer is deposited on the insulator layer. The top and bottom electrode layers, the insulator layer, and the interfacial layer are patterned to form a MIM capacitor.
