The nomenclature sets the stage for understanding the underlying reactions that make ferric chloride good at etching copper. In solution, ferric chloride rapidly dissociates into iron (III ...

Gently pour in 1-cup Muriatic acid, to create the etching solution. Always wear goggles, gloves, and do not inhale the fumes. Do not use any metal containers, measuring cups, stainless steel sinks ...

These fluorination and ligand-exchange reactions lead to atomic layer controlled etching. This ALE approach is extendible to other materials besides metal oxides. Our current work has demonstrated the ...

Reactive Ion Etch (RIE) is a physical etch process. A rich plasma has been made just above the wafer, and the ions are expedited toward the surface to generate a highly powerful anisotropic etch.
