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.

Abstract: Describe is a resonator that uses ferroelectric (FE) materials in the gate of a transistor as a dielectric. The use of FE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, FE material expands or contacts depending on the applied electric field on the gate of the transistor. As such, acoustic waves are generated by switching polarization of the FE materials. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above the FE based transistor.
