Abstract:
1. A device comprising: a substrate layer, a porous dielectric layer adjacent the substrate layer with an exposed pore having an opening, wherein the exposed pore is disposed on at least one of a surface of the porous dielectric layer and a sidewall of a trench disposed within the porous dielectric layer; and a barrier across the opening of the exposed pore, wherein the barrier comprises a first barrier molecule with a silicon atom coupled to a surface of one side of the exposed pore, a sulfur atom, and a flexible chain between the silicon atom and the sulfur atom, wherein the flexible chain comprises a portion of a bridge structure that is capable of sealing the surface of the exposed pore, and a second barrier molecule with a silicon atom coupled to a surface of an opposite side of the exposed pore, wherein the first and second barrier molecules are connected to each other across the surface of the exposed pore.
