    Abstract: In some embodiments, the present disclosure, relates to an integrated chip. The integrated chip has an isolation structure arranged within a substrate. The isolation structure has interior surfaces defining one or more divots recessed below an uppermost surface of the isolation structure and sidewalls defining an opening exposing the substrate. A source region is disposed within the opening. A drain region is also disposed within the opening and is separated from the source region by a channel region along a first direction. A gate structure extends over the channel region. The gate structure includes a first gate electrode region having a first composition of one or more materials and a second gate electrode region disposed over the one or more divots and having a second composition of one or more materials different than the first composition of one or more materials.

    Abstract: In the present disclosure, it has been appreciated that memory structures, such as static random access memory (SRAM) structures, have feature densities that are extremely high. While this is beneficial in allowing the memory structures to store large amounts of data in a small chip footprint, it is potentially detrimental in that it makes the memory structures more susceptible to leakage current than the other areas of the chip. Accordingly, the present disclosure provides pseudo memory structures which are similar in terms of layout spacing to actual memory structures. However, rather than being used as actual memory structures that store data during operation, these pseudo memory structures are used to characterize leakage current in the design of the IC and/or to characterize the fabrication process used to manufacture the IC.

    Abstract: A semiconductor device including vertical transistors with a back side power structure, and methods of making the same are described. In one example, a described semiconductor structure includes: a gate structure including a gate pad and a gate contact on the gate pad; a first source region disposed below the gate pad; a first drain region disposed on the gate pad, wherein the first source region, the first drain region and the gate structure form a first transistor; a second source region disposed below the gate pad; a second drain region disposed on the gate pad, wherein the second source region, the second drain region and the gate structure form a second transistor; and at least one metal line that is below the first source region and the second source region, and is electrically connected to at least one power supply.

    Abstract: The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a substrate having interior surfaces that define a trench within an upper surface of the substrate. One or more dielectric materials are disposed within the trench. A source region disposed within the substrate and a drain region is disposed within of the substrate and separated from the source region along a first direction. A gate structure is over the upper surface of the substrate between the source region and the drain region. The upper surface of the substrate has a first width directly below the gate structure that is larger than a second width of the upper surface of the substrate within the source region or the drain region. The first width and the second width are measured along a second direction that is perpendicular to the first direction.

    Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip. The method includes forming an isolation structure within an upper surface of a substrate. The isolation structure surrounds a continuous region of the substrate defining a source area, a drain area, and a channel area. A gate structure is formed over the channel area. An implantation process is performed to form a source region within the source area and a drain region within the drain area. The channel area is arranged between the source region and the drain region along a first direction and extends past the source region and the drain region along a second direction that is perpendicular to the first direction. The first direction and the second direction are parallel to the upper surface of the substrate.
