  • Patent number: 8945305
    Abstract: Methods for depositing a material, such as a metal or a transition metal oxide, using an ALD (atomic layer deposition) process and resulting structures are disclosed. Such methods include treating a surface of a semiconductor structure periodically throughout the ALD process to regenerate a blocking material or to coat a blocking material that enables selective deposition of the material on a surface of a substrate. The surface treatment may reactivate a surface of the substrate toward the blocking material, may restore the blocking material after degradation occurs during the ALD process, and/or may coat the blocking material to prevent further degradation during the ALD process. For example, the surface treatment may be applied after performing one or more ALD cycles. Accordingly, the presently disclosed methods enable in situ restoration of blocking materials in ALD process that are generally incompatible with the blocking material and also enables selective deposition in recessed structures.

  • Patent number: 8753933
    Abstract: Methods of selectively forming a conductive material and methods of forming metal conductive structures are disclosed. An organic material may be patterned to expose regions of an underlying material. The underlying material may be exposed to a precursor gas, such as a platinum precursor gas, that reacts with the underlying material without reacting with the remaining portions of the organic material located over the underlying material. The precursor gas may be used in an atomic layer deposition process, during which the precursor gas may selectively react with the underlying material to form a conductive structure, but not react with the organic material. The conductive structures may be used, for example, as a mask for patterning during various stages of semiconductor device fabrication.
