Web4 jun. 1998 · Thin films of molybdenum were etched both within and downstream from a Cl 2 plasma at 200‐mTorr pressure and temperatures below 180 °C. When samples were positioned downstream from the discharge, etching proceeded solely by chemical reaction of the film with chlorine atoms. Without a discharge, molecular chlorine did not etch … WebMolybdenum Nanopillars Cryogenic etching Shape control Hydrogen silsesquioxane negative resist ABSTRACT We report on the fabrication of molybdenum (Mo) nanopillar (NP) arrays with NP diameters down to 75 nm by means of deep-reactive ion etching at cryogenic temperatures.
