Abstract:
A method of anisotropic etching comprises forming a metal layer above a substrate. A mask layer is formed on the metal layer with openings defined in the mask layer to expose portions of the metal layer. The exposed portions of the metal layer are introduced to an active etchant solution that includes nanoparticles as an insoluble banking agent. In further embodiments, the exposed portions of the metal layer are introduced to a magnetic and/or an electrical field.

Claim (Index 19):
The method of  claim 18 , wherein the electric field causes charges to aggregate along an etching cavity sidewall to slow an etching rate at the sidewall, resulting in preferential downward etching by suppressing undercut.
