WebJan 20, 2015 · The atomic layer etching (ALE) of Al2O3 was demonstrated using sequential, self-limiting thermal reactions with tin(II) acetylacetonate (Sn(acac)2) and hydrogen fluoride (HF) as the reactants. The Al2O3 samples were Al2O3 atomic layer deposition (ALD) films grown using trimethylaluminum and H2O. The HF source was HF … Web1. A method for dry etching an Al 2 O 3 film which has a thickness of 200 nm to 1,000 nm, and is arranged on a nickel chrome alloy film of a sample having a ruthenium film arranged on the Al 2 O 3 film, comprising the steps of: dry etching the ruthenium film using a gas mixture containing Cl 2 O 2 and Ar, so as to form an etched ruthenium film ...
WebMar 7, 2005 · The etch characteristics of films were investigated for MERIE and ICP plasma etch reactors as a function of chamber settings and gas chemistry. Compared to pure Ar sputtering, F-, Cl-, and Br-based plasma provided a significant chemical enhancement. Fluorine containing plasma produce higher etch rates compared to Cl and Br.
