Classification: CPC H | IPC H

Claim 0:
1. An integrated circuit device, comprising:
a capacitor comprising a ferroelectric oxide between first and second electrodes; and
the ferroelectric oxide having a perovskite crystal structure, wherein a lattice of the perovskite crystal structure comprises:
corner sites interchangeably occupied by one or more base corner elements and one or more dopant corner elements, and
center sites interchangeably occupied by one or more base center elements and one or more dopant center elements,

wherein upon application of a bias between the first and second electrodes, the capacitor exhibits a lower leakage current relative to a reference capacitor that is arranged to be the same as the capacitor except for the presence of the dopant center elements and placed under the same bias.
