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 2):
The method of  claim 1 , wherein the nanoparticles comprise at least one of Silicon, Titanium, Silver, Gold, Carbon, Tin, Lead, Zinc, Magnesium, Germanium, Chromium, Tantalum, platinum, oxides thereof, alloys thereof, and alloys with magnetically sensitive metals including Nickel, Iron, and Cobalt.
