ABSTRACTHo2O3-TiO2 based metal-insulator-metal capacitors were grown by ALD, using Ho(thd)3, Ti(OCH(CH3)2)4 and ozone as precursors. The thicknesses of the films were in the range of 7.7 to 25 nm. Some of the films were post-deposited annealed in order to study the treatment effects. The capacitors were electrically characterized. Leakage current decreases as the amount of holmium increased in the films. Resistive switching behavior was obtained in the samples where the leakage current was low. This effect was also observed in Ho2O3 films, where no titanium was present in the films.

Resistive switching (RS) effects in Pt/HfO2/TiN metal-insulator-metal (MIM) capacitors have been investigated in dependence on the TiN bottom electrode engineering, deposition process, switching conditions and dielectric thickness. It is found that RS ratio depends strongly on the amount of oxygen introduced on TiN surface during interface engineering. In some structures a full recovery of conductive filament is observed within more than 100 switching cycles. RS effects are discussed in terms of different energy needed to dissociate O ions in structures with different TiN electrode treatment.
