Abstract
An IC device comprises a stack of contact levels, each including conductive layer and an insulation layer. A dielectric liner surrounds an interlevel conductor within an opening in the stack of contact levels. The opening passes through a portion of the stack of contact levels. The interlevel conductor is electrically insulated from the conductive layers of each of the contact levels through the dielectric liner. A portion of the conductive layer at the opening is recessed relative to adjacent insulation layers. The dielectric liner may have portions extending between adjacent insulation layers.
