摘要： A memory structure includes a spacer between a first side of a wordline conductor and a bitline conductor. A semiconductor material has horizontal portions extending from the bitline conductor along a top and bottom of the wordline conductor and has a contact portion extending along a second side of the wordline conductor between and connecting the horizontal portions. A high-κ dielectric is between the semiconductor material and the wordline conductor. A capacitor has a first conductor, a second conductor, and an insulator between the first and second conductors, where the first conductor contacts the contact portion of the semiconductor material along the first side of the wordline conductor, and the second conductor connects to a ground terminal.

摘要： Gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, and methods of fabricating gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, are described. For example, an integrated circuit structure includes an insulator fin on an insulator substrate. A vertical arrangement of horizontal semiconductor nanowires is over the insulator fin. A gate stack surrounds a channel region of the vertical arrangement of horizontal semiconductor nanowires, and the gate stack is overlying the insulator fin. A pair of epitaxial source or drain structures is at first and second ends of the vertical arrangement of horizontal semiconductor nanowires and at first and second ends of the insulator fin.

摘要： A first interconnect layer is bonded to a first substrate. The first interconnect layer is deposited on a first device layer on a second device layer on a second substrate. The second device layer is revealed from the second substrate side. A first insulating layer is deposited on the revealed second device layer. A first opening is formed in the first insulating layer to expose a first portion of the second device layer. A contact region is formed on the exposed first portion of the second device layer.
