Abstract:
A memory device may include an active device region, disposed at least partially in a first level. The memory device may include a storage capacitor, disposed at least partially in a second level, above the first level, wherein the first level and the second level are parallel to a substrate plane. The memory device may also include a contact via, the contact via extending between the storage capacitor and the active device region, and defining a non-zero angle of inclination with respect to a perpendicular to the substrate plane.
