    摘要: Described herein are three-dimensional transistors with a recessed gate, and IC devices including such three-dimensional transistors with recessed gates. The transistor includes a channel material having a recess. The channel material is formed over a support structure, and source/drain regions are formed in or on the channel material, e.g., one either side of the recess. A gate stack extends through the recess. The distance between the gate stack and the support structure is smaller than the distance between one of the source/drain regions and the support structure. This arrangement increases the channel length relative to prior art transistors, reducing leakage.

    摘要: Microelectronic assemblies fabricated using hybrid manufacturing with modified via-last process are disclosed. The fabrication approach is based on using hybrid manufacturing to bond first and second IC structures originally provided on different dies but filling at least portions of vias that are supposed to couple across a bonding interface between the first and second IC structures with electrically conductive materials after the IC structures have been bonded. A resulting microelectronic assembly that includes the first and second IC structures bonded together may have vias extending through all of the first IC structure and into the second IC structure, thus providing electrical coupling between one or more components of the first IC structure and those of the second IC structure, where an electrically conductive material in the individual vias is continuous through the first IC structure and at least a portion of the second IC structure.

    摘要: Techniques and mechanisms for improved performance characteristics of a transistor device. In an embodiment, a transistor of an integrated circuit comprises a source, a drain, a gate, a gate dielectric and a semiconductor structure which adjoins the gate dielectric. The semiconductor structure is configured to provide a conductive channel between the source and drain. The semiconductor structure includes first, second and third portions, the second portion between the source and the gate, and the third portion between the drain and the gate, wherein the first portion connects the second portion and third portion to one another. A thickness of the first portion is less than another thickness of one of the second portion or the third portion. In another embodiment, the locations of thicker portions of semiconductor structure mitigate overall transistor capacitance, while a thinner intermediary portion of the semiconductor structure promotes good sub-threshold swing characteristics.

    摘要: Microelectronic assemblies fabricated using hybrid manufacturing, as well as related devices and methods, are disclosed herein. As used herein, “hybrid manufacturing” refers to fabricating a microelectronic assembly by arranging together at least two IC structures fabricated by different manufacturers, using different materials, or different manufacturing techniques. For example, a microelectronic assembly may include a first IC structure that includes first interconnects and a second IC structure that includes second interconnects, where at least some of the first and second interconnects may include a liner and an electrically conductive fill material, and where a material composition of the liner/electrically conductive fill material of the first interconnects may be different from a material composition of the liner/electrically conductive fill material of the second interconnects.

    摘要: Thin film transistor structures and processes are disclosed that include stacked nanowire bodies to mitigate undesirable short channel effects, which can occur as gate lengths scale down to sub-100 nanometer (nm) dimensions, and to reduce external contact resistance. In an example embodiment, the disclosed structures employ a gate-all-around architecture, in which the gate stack (including a high-k dielectric layer) wraps around each of the stacked channel region nanowires (or nanoribbons) to provide improved electrostatic control. The resulting increased gate surface contact area also provides improved conduction. Additionally, these thin film structures can be stacked with relatively small spacing (e.g., 1 to 20 nm) between nanowire bodies to increase integrated circuit transistor density. In some embodiments, the nanowire body may have a thickness in the range of 1 to 20 nm and a length in the range of 5 to 100 nm.
