Abstract: Embodiments herein describe techniques for an integrated circuit that includes a substrate, a semiconductor device on the substrate, and a contact stack above the substrate and coupled to the semiconductor device. The contact stack includes a contact metal layer, and a semiconducting oxide layer adjacent to the contact metal layer. The semiconducting oxide layer includes a semiconducting oxide material, while the contact metal layer includes a metal with a sufficient Schottky-barrier height to induce an interfacial electric field between the semiconducting oxide layer and the contact metal layer to reject interstitial hydrogen from entering the semiconductor device through the contact stack. Other embodiments may be described and/or claimed.

Abstract: A thin film transistor (TFT) structure includes a gate electrode, a gate dielectric layer on the gate electrode, a channel layer including a semiconductor material with a first polarity on the gate dielectric layer. The TFT structure also includes a multi-layer material stack on the channel layer, opposite the gate dielectric layer, an interlayer dielectric (ILD) material over the multi-layer material stack and beyond a sidewall of the channel layer. The TFT structure further includes source and drain contacts through the interlayer dielectric material, and in contact with the channel layer, where the multi-layer material stack includes a barrier layer including oxygen and a metal in contact with the channel layer, where the barrier layer has a second polarity. A sealant layer is in contact with the barrier layer, where the sealant layer and the ILD have a different composition.

Abstract: A two-terminal ferroelectric perovskite diode comprises a region of ferroelectric perovskite material positioned adjacent to a region of n-type doped perovskite semiconductor material. Asserting a positive voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a first direction that causes the diode to be placed in a low resistance state due to the formation of an accumulation region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor boundary. Asserting a negative voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a second direction that causes the diode to be placed in a high resistance state due to the formation of a depletion region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor material. These non-volatile low and high resistance states enable the diode to be used as a non-volatile memory element.

Abstract: An integrated circuit (IC) structure in a memory device is described. In an example, the IC structure includes a memory cell including a bitline (BL) extending along a first direction and a channel extending along a second direction above and diagonal to the BL. In the example, a wordline (WL) extends in a third direction perpendicular to the first direction of the BL and intersects with the channel to control a current in the channel along a gated channel length. In some examples, the channel is electrically coupled on a first side to a storage capacitor via a storage node contact (SNC) and on a second side to the BL via a bit line contact (BLC) located on an underside or backside of the channel.

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. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be etched away, leaving the doped semiconductor layers as fins for a ribbon FET. A ferroelectric layer can be conformally grown on the fins, creating a high-quality ferroelectric layer above and below the fins. A gate can then be grown on the ferroelectric layer.

Abstract: Contacts to n-type source/drain regions comprise a phosphide or arsenide metal compound layer. The phosphide or arsenide metal compound layers can aid in forming thermally stable low resistance contacts. A phosphide or arsenide metal compound layer is positioned between the source/drain region and the contact metal layer of the contact. A phosphide or arsenic metal compound layer can be used in contacts contacting n-type source/drain regions comprising phosphorous or arsenic as the primary dopant, respectively. The phosphide or arsenide metal compound layers prevent diffusion of phosphorous or arsenic from the source/drain region into the metal contact layer and dopant deactivation in the source/drain region due to annealing and other high-temperature processing steps that occur after contact formation. Phosphide and arsenide metal contact layers can also reduce the amount of silicide that forms in source/drain regions during processing by limiting the amount of contact metal that diffuses into source/drain regions.
