Abstract: Techniques and mechanisms for providing electrical insulation or other protection of an integrated circuit (IC) device with a spacer structure which comprises an (anti)ferromagnetic material. In an embodiment, a transistor comprises doped source or drain regions and a channel region which are each disposed in a fin structure, wherein a gate electrode and an underlying dielectric layer of the transistor each extend over the channel region. Insulation spacers are disposed on opposite sides of the gate electrode, where at least a portion of one such insulation spacer comprises an (anti)ferroelectric material. Another portion of the insulation spacer comprises a non-(anti)ferroelectric material. In another embodiment, the two portions of the spacer are offset vertically from one another, wherein the (anti)ferroelectric portion forms a bottom of the spacer.
