A semiconductor structure and method wherein a recess is disposed in a
surface portion of a semiconductor structure and a dielectric film is
disposed on and in contract with the semiconductor. The dielectric film
has an aperture therein. Portions of the dielectric film are disposed
adjacent to the aperture and overhang underlying portions of the recess.
An electric contact has first portions thereof disposed on said adjacent
portions of the dielectric film, second portions disposed on said
underlying portions of the recess, with portions of the dielectric film
being disposed between said first portion of the electric contact and the
second portions of the electric contact, and third portions of the
electric contact being disposed on and in contact with a bottom portion
of the recess in the semiconductor structure. The electric contact is
formed by atomic layer deposition of an electrically conductive material
over the dielectric film and through the aperture in such dielectric
film.
