An integrated circuit (IC) includes a first memory cell and a second memory cell. The first memory cell includes (i) a first transistor and (ii) a first capacitor coupled to the first transistor, where an upper electrode of the first capacitor is coupled to a first conductive structure. The second memory cell is above the first memory cell. The second memory cell includes (i) a second transistor and (ii) a second capacitor coupled to the second transistor. An upper electrode of the second capacitor is coupled to a second conductive structure. In an example, an interconnect feature includes a continuous and monolithic body of conductive material. In an example, the continuous and monolithic body extends through the second conductive structure, and further extends through the first conductive structure. In an example, the first and second memory cells are dynamic random access memory (DRAM) memory cells.

Punch-through interconnect feature to couple upper electrodes of capacitors of multi-level memory arrays

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

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.
