Centrifugal Etching

open access: yesJournal of The Electrochemical Society, 2003
A cell consisting of a rotatable double-walled cylinder is described for the study of etching under conditions of enhanced gravity. Rotation rates of 6000 revolutions per minute giving g values of up to 600 were possible with the set-up. The cell was tested by etching masked patterns in a copper plate with an aqueous FeCl3 solution.

Crystallographically Determined Etching and Its Relevance to the Metal-Assisted Catalytic Etching (MACE) of Silicon Powders

open access: yesFrontiers in Chemistry, 2019
Metal-assisted catalytic etching (MACE) using Ag nanoparticles as catalysts and H2O2 as oxidant has been performed on single-crystal Si wafers, single-crystal electronics grade Si powders, and polycrystalline metallurgical grade Si powders.

Manipulating etch selectivities in XeF2 vapour etching [PDF]

open access: yes, 2021
The vapour etching of silicon sacrificial layers is often a critical process in the fabrication of micro/nanosystems. This method has a number of attractive features, in particular, high etch rates of sacrificial silicon layers and good selectivities associated with photoresist, SiO₂, stoichiometric Si₃N₄ and a number of regularly used metal films ...
