Embodiments herein describe techniques for a semiconductor device including a substrate. A first capacitor includes a first top plate and a first bottom plate above the substrate. The first top plate is coupled to a first metal electrode within an inter-level dielectric (ILD) layer to access the first capacitor. A second capacitor includes a second top plate and a second bottom plate, where the second top plate is coupled to a second metal electrode within the ILD layer to access the second capacitor. The second metal electrode is disjoint from the first metal electrode. The first capacitor is accessed through the first metal electrode without accessing the second capacitor through the second metal electrode. Other embodiments may be described and/or claimed.

Capacitor connections in dielectric layers

Integrated circuit structures having differentiated interconnect lines in a same dielectric layer, and methods of fabricating integrated circuit structures having differentiated interconnect lines in a same dielectric layer, are described. In an example, an integrated circuit structure includes an inter-layer dielectric (ILD) layer above a substrate. A plurality of conductive interconnect lines is in the ILD layer. The plurality of conductive interconnect lines includes a first interconnect line having a first height, and a second interconnect line immediately laterally adjacent to but spaced apart from the first interconnect line, the second interconnect line having a second height less than the first height.

Integrated circuit structures having differentiated interconnect lines in a same dielectric layer

Embodiments herein describe techniques for a semiconductor device including a substrate, a first inter-level dielectric (ILD) layer above the substrate, and a second ILD layer above the first ILD layer. A first capacitor and a second capacitor are formed within the first ILD layer and the second ILD layer. A first top plate of the first capacitor and a second top plate of the second capacitor are formed at a boundary between the first ILD layer and the second ILD layer. The first capacitor and the second capacitor are separated by a dielectric area in the first ILD layer. The dielectric area includes a first dielectric area that is coplanar with the first top plate or the second top plate, and a second dielectric area above the first dielectric area and to separate the first top plate and the second top plate. Other embodiments may be described and/or claimed.

Capacitor separations in dielectric layers

Embodiments herein describe techniques for a memory device including at least two memory cells. A first memory cell includes a first storage cell and a first transistor to control access to the first storage cell. A second memory cell includes a second storage cell and a second transistor to control access to the second storage cell. A shared contact electrode is shared between the first transistor and the second transistor, the shared contact electrode being coupled to a source area or a drain area of the first transistor, coupled to a source area or a drain area of the second transistor, and further being coupled to a bit line of the memory device. Other embodiments may be described and/or claimed.

Memory architecture with shared bitline at back-end-of-line

Embodiments herein describe techniques for a semiconductor device including a substrate. A first set of memory cells and a first selector are formed within a first group of metal layers and inter-level dielectric (ILD) layers above the substrate. A second set of memory cells and a second selector are formed within a second group of metal layers and ILD layers above the first group of metal layers and ILD layers. The first selector is coupled to the first set of memory cells to select one or more memory cells of the first set of memory cells based on a first control signal. In addition, the second selector is coupled to the second set of memory cells to select one or more memory cells of the second set of memory cells based on a second control signal. Other embodiments may be described and/or claimed.

Memory architecture at back-end-of-line

Embodiments herein describe techniques for a semiconductor device having an interconnect structure including an inter-level dielectric (ILD) layer between a first layer and a second layer of the interconnect structure. The interconnect structure further includes a separation layer within the ILD layer. The ILD layer includes a first area with a first height to extend from a first surface of the ILD layer to a second surface of the ILD layer. The ILD layer further includes a second area with a second height to extend from the first surface of the ILD layer to a surface of the separation layer, where the first height is larger than the second height. Other embodiments may be described and/or claimed.

Intermediate separation layers at the back-end-of-line

Embodiments herein describe techniques for a semiconductor device including a substrate oriented in a horizontal direction, and a memory cell including a transistor and a capacitor above the substrate. The transistor includes a gate electrode oriented in a vertical direction substantially orthogonal to the horizontal direction, and a channel layer oriented in the vertical direction, around the gate electrode and separated by a gate dielectric layer from the gate electrode. The capacitor is within an inter-level dielectric layer above the substrate. The capacitor includes a first plate coupled with a second portion of the channel layer of the transistor, and a second plate separated from the first plate by a capacitor dielectric layer. The first plate of the capacitor is also a source electrode of the transistor. Other embodiments may be described and/or claimed.
