Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques directed to creating a transistor structure by selectively growing a 2D TMD directly in a stacked channel configuration, such as a stacked nanowire or nanoribbon formation. In embodiments, this TMD growth may occur for all of the nanowires or nanoribbons in the transistor structure in one stage. Placement of a SAM on a plurality of dielectric layers within the transistor structure stack facilitates channel deposition and channel geometry in the stacked channel configuration. Other embodiments may be described and/or claimed.

Abstract: Thin film transistors having strain-inducing structures integrated with two-dimensional (2D) channel materials are described. In an example, an integrated circuit structure includes a two-dimensional (2D) material layer above a substrate. A gate stack is on the 2D material layer, the gate stack having a first side opposite a second side. A first gate spacer is on the 2D material layer and adjacent to the first side of the gate stack. A second gate spacer is on the 2D material layer and adjacent to the second side of the gate stack. The first gate spacer and the second gate spacer induce a strain on the 2D material layer. A first conductive structure is on the 2D material layer and adjacent to the first gate spacer. A second conductive structure is on the 2D material layer and adjacent to the second gate spacer.

Two or more ferroelectric capacitors are through the series of alternating plate lines and an insulating material such that a first one of the ferroelectric capacitors is coupled to a first one of the plate lines and a second one of the ferroelectric capacitors is coupled to a second one of the plate lines. A plurality of substantially parallel bitlines is along a first direction over the two or more ferroelectric capacitors. A plurality of substantially parallel bitlines is along a first direction over the two or more ferroelectric capacitors. A plurality of substantially parallel wordlines is along a second direction orthogonal to the first direction over the two or more ferroelectric capacitors. An access transistor is located over and controls the two or more ferroelectric capacitors, the access transistor incorporating a first one of the bitlines and a first one of the wordlines. The bitline comprise a first source/drain of a source/drain pair, and a second source/drain is aligned, and in contact, with a top one of the two or more ferroelectric capacitors, and the first wordline forms a gate of the access transistor.
