Abstract: Described herein are gate-all-around (GAA) transistors with extended drains, where the drain region extends through a well region below the GAA transistor. A high voltage can be applied to the drain, and the extended drain region provides a voltage drop. The transistor length (and, specifically length of the extended drain) can be varied based on the input voltage to the device, e.g., providing a longer drain for higher input voltages. The extended drain transistors can be implemented in devices that include CFETs, either by implementing the extended drain transistor across both CFET layers, or by providing a sub-fin pedestal with the well regions in the lower layer.

Abstract: Techniques to form semiconductor device conductive interconnections. In an example, an integrated circuit includes a recessed via and a conductive bridge between a top surface of the recessed via and an adjacent source or drain contact. A transistor device includes a semiconductor material extending from a source or drain region, a gate structure over the semiconductor material, and a contact on the source or drain region. Adjacent to the source or drain region, a deep via structure extends in a vertical direction through an entire thickness of the gate structure. The via structure includes a conductive via that is recessed below a top surface of the conductive contact. A conductive bridge extends between the contact and the conductive via such that the conductive bridge contacts a portion of the contact and at least a portion of a top surface of the conductive via.

Abstract: Disclosed herein are IC structures, packages, and devices that include III-N transistor arrangements that may reduce nonlinearity of off-state capacitance of the III-N transistors. In various aspects, III-N transistor arrangements limit the extent of access regions of the transistors, compared to conventional implementations, which may limit the depletion of the access regions. Due to the limited extent of the depletion regions of a transistor, the off-state capacitance may exhibit less variability in values across different gate-source voltages and, hence, exhibit a more linear behavior during operation.

Abstract: Technologies for a transistor with a thin-film ferroelectric gate dielectric are disclosed. In the illustrative embodiment, a transistor has a thin layer of scandium aluminum nitride (ScxAl1-xN) ferroelectric gate dielectric. The channel of the transistor may be, e.g., gallium nitride or molybdenum disulfide. In one embodiment, the ferroelectric polarization changes when voltage is applied and removed from a gate electrode, facilitating switching of the transistor at a lower applied voltage. In another embodiment, the ferroelectric polarization of a gate dielectric of a transistor changes when the voltage is past a positive threshold value or a negative threshold value. Such a transistor can be used as a one-transistor memory cell.

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a perovskite stack is grown on a buffer layer as part of manufacturing a transistor. The perovskite stack includes one or more doped semiconductor layers alternating with other lattice-matched layers, such as undoped semiconductor layers. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be preferentially etched away, leaving the doped semiconductor layers as fins for a ribbon FET. In another embodiment, an interlayer can be deposited on top of a semiconductor layer, and a ferroelectric layer can be deposited on the interlayer. The interlayer can bridge a gap in lattice parameters between the semiconductor layer and the ferroelectric layer.

Abstract: Disclosed herein are IC structures, packages, and devices that include III-N transistors implementing various means by which their threshold voltage it tuned. In some embodiments, a III-N transistor may include a doped semiconductor material or a fixed charge material included in a gate stack of the transistor. In other embodiments, a III-N transistor may include a doped semiconductor material or a fixed charge material included between a gate stack and a III-N channel stack of the transistor. Including doped semiconductor or fixed charge materials either in the gate stack or between the gate stack and the III-N channel stack of III-N transistors adds charges, which affects the amount of 2DEG and, therefore, affects the threshold voltages of these transistors.
