Large remnant polarization and great reliability characteristics in W/HZO/W ferroelectric capacitors

Frontiers in Materials, 2022
In this work, the effect of rapid thermal annealing (RTA) temperature on the ferroelectric polarization in zirconium-doped hafnium oxide (HZO) was studied. To maximize remnant polarization (2Pr), in-plane tensile stress was induced by tungsten electrodes

Room temperature PVD TiN to improve the ferroelectric properties of HZO films in the BEoL

, 2022
S.535-539Zirconium-doped hafnium oxide (HZO) crystallizes at low temperatures and is thus ideal to implement ferroelectric (FE) functionalities into the back end of line (BEoL). Therefore, metal-ferroelectric-metal (MFM) capacitors are of great interest.

Retention Improvement of HZO-Based Ferroelectric Capacitors with TiO₂ Insets

ACS Omega, 2022
The influence of the bottom TiO2 interfacial layer grown by atomic layer deposition on the ferroelectric properties of the TiN/Hf0.5Zr0.5O2/TiN capacitors is systematically investigated. We show that the integration of the TiO2 layer leads to an increase in the polar orthorhombic phase content in the Hf0.5Zr0.5O2 film.

Improvement in ferroelectricity of HfxZr1−xO2 thin films using top- and bottom-ZrO2 nucleation layers

APL Materials, 2019
A ferroelectric HfxZr1−xO2 (HZO) thin film crystallized with nanocrystalline top- and bottom-ZrO2 nucleation layers (D-ZrO2) exhibited superior remanent polarization (2Pr = Pr+ − Pr− = 29 μC/cm2) compared to that of similar thin films (12 μC/cm2 ...

Modelling Ferroelectric Hysteresis of HZO Capacitor with Jiles-Atherton Model for Non-Volatile Memory Applications

, 2023
We report a ferroelectric model based on the Jiles-Atherton equations which can successfully reproduce the experimental polarization-voltage hysteresis of thin-film hafnium zirconium oxide (HZO) capacitor devices.
