Abstract: Various embodiments of the present disclosure are directed towards an integrated chip including a dielectric structure sandwiched between a first electrode and a bottom electrode. A passivation layer overlies the second electrode and the dielectric structure. The passivation layer comprises a horizontal surface vertically below a top surface of the passivation layer. The horizontal surface is disposed above a top surface of the dielectric structure.

Abstract: An antiferroelectric field effect transistor (Anti-FeFET) of a memory cell includes an antiferroelectric layer instead of a ferroelectric layer. The antiferroelectric layer may operate based on a programmed state and an erased state in which the antiferroelectric layer is in a fully polarized alignment and a non-polarized alignment (or a random state of polarization), respectively. This enables the antiferroelectric layer in the FeFET to provide a sharper/larger voltage drop for an erase operation of the FeFET (e.g., in which the FeFET switches or transitions from the programmed state to the erased state) relative to a ferroelectric material layer that operates based on switching between two opposing fully polarized states.

Abstract: An isolation device for oil circuit contains a first clamper and the second clamper which include a first clamping portion and a second clamping and two grip portions; the first clamping portion having a first plug and a notch; the second clamper being located at a recess of the notch, and the recess having a post extending upwardly, the post having a groove formed therein for inserting a fixing member, a disc, a compression spring, and a washer, the fixing member being received in the recess of the second clamper and having a plurality of ribs, the disc having a plurality of slots; the disc having a first cutout, a second cutout, and a third cutout provided in an array arrangement, wherein the first cutout, the second cutout, and the third cutout are in different sizes, and the disc also having a second plug in different sizes.
