Patent ID: 7525140

Claim:
A device comprising: a base; a first insulating layer on said base; a first electrode on said first insulating layer; a dielectric film on said first electrode; a second electrode on said dielectric film; and a second insulating layer on said second electrode, wherein: an adhesion hole set extends in a vertical direction through said first electrode, said dielectric film, and said second electrode; a portion of said second insulating layer contacts said first insulating layer within said adhesion hole set; said first insulating layer and said second insulating layer fill said adhesion hole set to the exclusion of any other material; said first electrode, said dielectric film, and said second electrode form a structure having a cross-sectional area lying in a horizontal dimension that is substantially perpendicular to the vertical direction; the cross-sectional area is bounded by a perimeter, and said adhesion hole set is entirely contained within said perimeter.
