Abstract
A memory device includes a bottom electrode having an uppermost surface, a first sidewall, and a second sidewall. The memory device further includes a dielectric layer covering the uppermost surface and the first and second sidewalls of the bottom electrode such that an uppermost surface of the dielectric layer is arranged higher than the uppermost surface of the bottom electrode. The memory device further includes a metal body in direct contact with the uppermost surface of the bottom electrode and extending through the dielectric layer to the uppermost surface of the dielectric layer. The memory device further includes a memory component arranged in direct contact with the metal body and with the uppermost surface of the dielectric layer.
