Abstract:
1. A method for forming a dielectric film, the method comprising: a) providing in a deposition reaction chamber a substrate having a gap on a surface, the gap having a top opening and a surface area comprising a bottom and sidewalls running from the top to the bottom; and b) selectively depositing a dielectric film in the gap by: applying a film formation catalyst or a catalyst precursor on at least a portion of the gap surface area; exposing the substrate surface to a precursor gas such that a dielectric layer is preferentially formed on said at least a portion of the gap surface area; and solidifying the as-formed dielectric layer to form a solid dielectric layer on said at least a portion of the gap surface area, further comprising selectively inhibiting film growth at a portion of the gap with an agent.
