  • Publication number: 20240128333
    Abstract: A semiconductor structure is provided including a backside source/drain contact structure that contacts a source/drain region of a transistor and overlaps a portion of a tri-layered bottom dielectric isolation structure that is located on a backside of the transistor. The presence of the tri-layered bottom dielectric isolation structure prevents shorting between the gate structure of the transistor and the backside source/drain contact structure, and thus improves process margin.

  • Publication number: 20240121966
    Abstract: A memory device includes a substrate and vertically stacked ferroelectric capacitors formed on the substrate. A first ferroelectric capacitor has a different capacitive output than a second ferroelectric capacitor when a constant voltage is applied. First and second electrodes are in electrical contact with the vertically stacked ferroelectric capacitors. In some instances, a first capacitor plate in the first ferroelectric capacitor and a second capacitor plate in the second ferroelectric capacitor have different thicknesses. The different thicknesses allow the capacitive output for each capacitor to produce different electric field outputs. Accordingly, a combination of different output signals can be produced based on different threshold voltage levels for each capacitor contributing to the output.

  • Publication number: 20240113117
    Abstract: Embodiments of the present invention are directed to stacked field effect transistors (SFETs) having integrated vertical inverters. In a non-limiting embodiment, a first nanosheet is vertically stacked over a second nanosheet. A common gate is formed around a channel region of the first and second nanosheets. A top source or drain region is formed in direct contact with the first nanosheet and a bottom source or drain region is formed in direct contact with the second nanosheet. A first portion of the top source or drain region is shorted to a first portion of the bottom source or drain region to define a common source or drain region. A second portion of the top source or drain region is electrically coupled to a second portion of the bottom source or drain region in series through the first nanosheet, the common source or drain region, and the second nanosheet.
