Polycrystalline hafnium dioxide (HfO2) films exhibit faster filament formation in resistance switching devices compared to amorphous films. Microstructure, particularly grain boundaries, significantly impacts switching kinetics and device variability.

Area of Science:

  • Materials Science
  • Solid-State Electronics
  • Nanotechnology

Background:

  • Commercialization of hafnium dioxide (HfO2) based resistance switching devices is hindered by variability.
  • Understanding the relationship between HfO2 thin film microstructure and device performance is crucial.

Purpose of the Study:

  • Investigate the impact of thermal processing on HfO2 thin film structure.
  • Analyze how HfO2 microstructure affects filament formation kinetics in p+ Si/HfO2/Cu and TiN/HfO2/Cu devices.

Main Methods:

  • Atomic layer deposition (ALD) of HfO2 thin films.
  • Ternary structure analysis of HfO2 films.
  • Filament formation kinetics analysis in fabricated devices.

Main Results:

  • Polycrystalline HfO2 films show filament formation times at least one order of magnitude shorter than amorphous films.
  • Fast ion migration along grain boundaries in polycrystalline films accelerates filament formation.
  • Filament formation times correlate with the degree of crystalline orientation within polycrystalline films.
  • Inter-device variability in forming time is consistent across different HfO2 processing conditions.

Conclusions:

  • HfO2 microstructure, specifically its crystalline nature and grain boundary density, critically influences filament forming kinetics.
  • The observed dependence of filament forming kinetics on HfO2 microstructure has significant implications for reducing inter-device variability in resistance switching devices.
