Nb2o5 atomic layer etching
WebAtomic layer etching (ALE) is the reverse of atomic layer deposition (ALD). ALE can be achieved using sequential, self-limiting thermal reactions. We have recently demonstrated Al 2 O 3 ALE [1-3] and HfO 2 ALE [4]. During the surface chemistry using HF and Sn (acac) 2 as the reactants, the HF converts the metal oxide to metal fluoride. WebAtomic layer etching (ALE) of Al2O3, HfO2, and ZrO2was accomplished using sequential exposures with hydrogen fluoride (HF) as the fluorination reagent and dimethylaluminum …
