Classification: CPC H | IPC H

Claim 0:
1. A metal-insulator-metal capacitor (MIMCAP) device comprising:
a first conductive electrode;
a first dielectric stack structure provided on the first conductive electrode;
a second conductive electrode provided on the first dielectric stack structure;
a second dielectric stack structure provided on the second conductive electrode; and
a third conductive electrode provided on the first dielectric stack structure,
wherein the first dielectric stack structure includes
a first dielectric layer comprising a first non-ferroelectric material in contact with the first conductive electrode,
a second ferroelectric dielectric layer comprising a second material in direct physical contact with the first dielectric layer, and
a third dielectric layer comprising a third non-ferroelectric material in contact with the second conductive electrode and in direct physical contact with the same second ferroelectric dielectric layer.
