Abstract:
A method is provided for fabricating a semiconductor device that includes providing a structure with a sacrificial layer having at least one through-hole exposing a metal surface and, optionally, an oxide surface. In one example, the method may include applying a self-assembled monolayer selectively on the exposed metal surface and/or on the oxide surface. The method may also include growing a metal on the self-assembled monolayer and on the exposed metal surface if no self-assembled monolayer is present thereon, so as to fill the at least one through-hole, thereby forming at least one metal structure. The method may further include replacing the first sacrificial layer by a replacement dielectric layer having a dielectric constant of at most 3.9.
