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: Embodiments herein describe techniques for a semiconductor device including a gate stack with a ferroelectric-oxide layer above a channel layer and in contact with the channel layer, and a top electrode above the ferroelectric-oxide layer. The ferroelectric-oxide layer includes a domain wall between an area under a nucleation point of the top electrode and above a separation line of the channel layer between an ON state portion and an OFF state portion of the channel layer. A resistance between a source electrode and a drain electrode is modulated in a range between a first resistance value and a second resistance value, dependent on a position of the domain wall within the ferroelectric-oxide layer, a position of the ON state portion of the channel layer, and a position of the OFF state portion of the channel layer. Other embodiments may be described and/or claimed.
