Abstract: Hybrid bonding interconnect (HBI) architectures for scalability. Embodiments implement a bonding layer on a semiconductor die that includes a thick oxide layer overlaid with a thin layer of a hermetic material including silicon and at least one of carbon and nitrogen. The conductive bonds of the semiconductor die are placed in the thick oxide layer and exposed at the surface of the hermetic material. Some embodiments implement a non-bonding moisture seal ring (MSR) structure.

Abstract: Perovskite oxide field effect transistors comprise perovskite oxide materials for the channel, source, drain, and gate oxide regions. The source and drain regions are doped with a higher concentration of n-type or p-type dopants (depending on whether the transistor is an n-type or p-type transistor) than the dopant concentration in the channel region to minimize Schottky barrier height between the source and drain regions and the source and drain metal contact and contact resistance.

Abstract: Techniques are disclosed for an integrated circuit including a ferroelectric gate stack including a ferroelectric layer, an interfacial oxide layer, and a gate electrode. The ferroelectric layer can be voltage activated to switch between two ferroelectric states. Employing such a ferroelectric layer provides a reduction in leakage current in an off-state and provides an increase in charge in an on-state. The interfacial oxide layer can be formed between the ferroelectric layer and the gate electrode. Alternatively, the ferroelectric layer can be formed between the interfacial oxide layer and the gate electrode.

The vertical transistor structure further includes a gate electrode adjacent to a sidewall of the stack, where the sidewall includes the channel material, and at least a partial thickness of both the source material and the drain material. A gate dielectric is present between the sidewall of the stack and the gate electrode. The vertical transistor structure further includes a first metallization over a first area of the stack above the gate dielectric layer, and in contact with the gate electrode on sidewall of the stack. A second metallization is adjacent to the first metallization, where the second metallization is over a second area of the stack, and in contact with the source material or the drain material.

Abstract: Described herein are capacitor devices formed using perovskite insulators. In one example, a perovskite templating material is formed over an electrode, and a perovskite insulator layer is grown over the templating material. The templating material improves the crystal structure and electrical properties in the perovskite insulator layer. One or both electrodes may be ruthenium. In another example, a perovskite insulator layer is formed between two layers of indium tin oxide (ITO), with the ITO layers forming the capacitor electrodes.

Abstract: A buffer layer is deposited on a substrate. A first III-V semiconductor layer is deposited on the buffer layer. A second III-V semiconductor layer is deposited on the first III-V semiconductor layer. The second III-V semiconductor layer comprises a channel portion and a source/drain portion. The first III-V semiconductor layer acts as an etch stop layer to etch a portion of the second III-V semiconductor layer to form the source/drain portion.
