A tunnel field-effect transistor and method fabricating the same are provided. The conduits formed by patterning a metal layer are lined by inert coating and caped by a photodefinable polymer layer that is affixed to the inert coating by with the help of an initially uncured polymer layer. The sock is fabricated of a pliable material and is configured to conform to the hoof of the horse when attached. A second matrix material may be selected to provide desired infiltration of hot, liquid binder material with the first matrix material to form a solid, coherent, composite matrix bit body.
