Abstract: IC devices with angled transistors and angled routing tracks, and related assemblies and methods, are disclosed herein. A transistor is referred to as an “angled transistor” if a longitudinal axis of an elongated semiconductor structure of the transistor (e.g., a fin or a nanoribbon) is neither perpendicular nor parallel to any edges of front or back sides of a support structure (e.g., a die) over which the transistor is implemented. Similarly, a routing track is referred to as an “angled routing track” if the routing track is neither perpendicular nor parallel to any edges of front or back faces of the support structure. Angled transistors and angled routing tracks provide a promising way to increasing densities of transistors on the limited real estate of semiconductor chips and/or decreasing adverse effects associated with continuous scaling of IC components.

Abstract: IC devices implementing 2T memory cells with source-drain coupling in one transistor, and related assemblies and methods, are disclosed herein. In particular, 2T memory cells presented herein use first and second transistors arranged so that source and drain terminals of the second transistor are coupled to one another. A memory state may be represented by charge indicative of the bit value stored in the second transistor, while the first transistor may serve as a switch to control access to the second transistor. 2T memory cells with source-drain coupling in one transistor provide a promising way to increasing memory cell densities, drive current, and design flexibility in making electrical connections to, or between, various transistor terminals and control lines of memory arrays, thus providing good scalability in the number of 2T memory cells included in memory arrays.

Abstract: Narrow-channel, non-planar transistors and their manufacture on integrated circuit dies. A method includes forming channel portions of transistors from sidewall spacers by removing backbone features and coupling a gate structure, a source, and a drain to the channel portions. An integrated circuit die includes a gate structure, a source, and a drain coupled to pair-symmetric channel portions with sidewalls of differing heights. A method includes iteratively etching away portions of semiconductor material not covered by a mask or a passivation layer, revealing a channel portion by removing the mask and passivation layer, and coupling a gate structure, a source, and a drain to the channel portion. An integrated circuit die includes a gate structure, a source, and a drain coupled to a channel portion with vertically alternating, greater and lesser widths.

Abstract: The scaling of features in ICs has been a driving force behind an ever-growing semiconductor industry. As transistors of the ICs become smaller, their gate lengths become smaller, leading to undesirable short-channel effects such as poor leakage, poor subthreshold swing, drain-induced barrier lowering, etc. Reducing transistor dimensions at the gate allows keeping the footprint of the transistor relatively small and comparable to what could be achieved implementing a transistor with a shorter gate length while effectively increasing transistor's effective gate length and thus reducing the negative impacts of short-channel effects. This architecture may be optimized even further if transistors are to be operated at relatively low temperatures, e.g., below 200 Kelvin degrees or lower.

Abstract: Disclosed herein are transistor gate-channel arrangements with transistor gate stacks that include dipole layers, and related methods and devices. Transistor gate stacks disclosed herein include a multilayer gate oxide having both a high-k dielectric and a dipole layer. In some embodiments, a thin dipole layer may directly border a channel material of choice and may be between the channel material and the high-k dielectric. In other embodiments, a passivation layer may spontaneously form between the dipole layer and the channel material. In still other embodiments, the high-k dielectric may be between the dipole layer and the channel material. Temporary polarization provided by the dipole layer may increase the effective dielectric constant of the high-k dielectric and may allow to use thinner high-k dielectrics and/or high-k dielectrics of suboptimal quality while maintaining transistor performance in terms of, e.g., gate leakage, carrier mobility, and subthreshold swing.

Abstract: An IC device may include memory layers bonded to a logic layer with inclination. An angle between a memory layer and the logic layer may be in a range from approximately 0 to approximately 90 degrees. The memory layers may be over the logic layer. The IC device may include one or more additional logic layers that are parallel to a memory layer or perpendicular to a memory layer. The one or more additional logic layers may be over the logic layer. A memory layer may include memory cells. The logic layer may include logic circuits (e.g., sense amplifier, word line driver, etc.) that control the memory cells. Bit lines (or word lines) in different memory layers may be coupled to each other. A bit line and a word line in a memory layer may be controlled by logic circuits in different logic layers.
