Abstract:
A ferroelectric device, comprising:first and second circuit elements associated with the ferroelectric device; and a ferroelectric capacitor having first and second conductive plates residing over a first interlayer dielectric layer that overlies the first and second circuit elements, wherein the first conductive plate of the ferroelectric capacitor extends between the first and second circuit elements, wherein the first circuit element couples to the conductive plate directly through a first contact that is in contact with the first conductive plate, and a second circuit element couples to the conductive plate directly through a second contact that is in contact with the first conductive plate, and wherein the conductive plate of the ferroelectric capacitor electrically couples together the circuit elements of the device, and wherein the second conductive plate extends between multiple, laterally electrically insulated metal segments of an overlying metal layer, and wherein the metal segments are coupled to the second conductive plate through a respective contact, thereby electrically coupling together the metal segments.
