Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity. Masking applications employing selective organic films are provided. Post-deposition modification of the organic films, such as metallic infiltration and/or carbon removal, is also disclosed.

Abstract: Methods are provided for selectively depositing Al and N containing material on a first conductive surface of a substrate relative to a second, dielectric surface of the same substrate. In some aspects, methods of forming an Al and N containing protective layer or etch stop layer for use in integrated circuit fabrication are provided.

Abstract: An apparatus and a method for forming a structure within a semiconductor processing apparatus are disclosed. The apparatus includes a first reaction chamber, the first reaction chamber configured to hold at least one substrate having a first layer. The apparatus also includes a precursor delivery system configured to perform an infiltration by sequentially pulsing a first precursor and a second precursor on the substrate. The apparatus may also include a first removal system configured for removing at least a portion of the first layer disposed on the substrate while leaving an infiltrated material, wherein the infiltration and the removing at least a portion of the first layer take place within the same semiconductor processing apparatus. A method of forming a structure within a semiconductor processing apparatus is also disclosed, the method including providing a substrate for processing in a reaction chamber, the substrate having a first layer disposed on the substrate. The method may also include performing a first layer infiltration by sequentially pulsing a first precursor and a second precursor on the substrate, wherein an infiltrated material forms in the first layer from the reaction of the first precursor and the second precursor. The method may also include removing at least a portion of the first layer disposed on the substrate after performing the infiltration, wherein the infiltration and the removing at least a portion of the first layer take place with the same semiconductor processing apparatus.
