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 24):
A method of anisotropic etching, the method comprising:\n forming a metal layer above a substrate; forming a mask layer on the metal layer with openings defined in the mask layer to expose portions of the metal layer; introducing the exposed portions of the metal layer to active etching solution including magnetically sensitive nanoparticles as an insoluble banking agent; exposing the active etching solution to a magnetic field that is perpendicular to an etching plane; and exposing the active etching solution to an electric field perpendicular to the etching plane.
