Abstract: Methods and apparatus for vapor deposition of an organic film are configured to vaporize an organic reactant at a first temperature, transport the vapor to a reaction chamber housing a substrate, and maintain the substrate at a lower temperature than the vaporization temperature. Alternating contact of the substrate with the organic reactant and a second reactant in a sequential deposition sequence can result in bottom-up filling of voids and trenches with organic film in a manner otherwise difficult to achieve. Deposition reactors conducive to depositing organic films are provided.

Abstract: Thermal atomic layer etching processes are disclosed. In some embodiments, the methods comprise at least one etch cycle in which the substrate is alternately and sequentially exposed to a first vapor phase halide reactant and a second vapor halide reactant. In some embodiments, the first reactant may comprise an organic halide compound. During the thermal ALE cycle, the substrate is not contacted with a plasma reactant.

Abstract: Methods are provided for dual selective deposition of a first material on a first surface of a substrate and a second material on a second, different surface of the same substrate. The selectively deposited materials may be, for example, metal, metal oxide, or dielectric materials.
