  • Publication number: 20240177992
    Abstract: The disclosure relates to methods of forming organic polymers comprising polyimide and layers comprising the same and to methods of reducing polyamic acid content of an organic polymer. The embodiments of the disclosure further relate to methods of fabricating semiconductor devices, to selectively depositing a material on a surface of a semiconductor substrate and to semiconductor processing assemblies. The methods are characterized by contacting a polyimide-containing material, such as a layer, with a modifying agent that increases the proportion of polyimide in the organic polymer material.

  • Publication number: 20240162036
    Abstract: The disclosure relates to methods and deposition assemblies for selectively depositing material including silicon and nitrogen on a first surface of a substrate relative to the second surface of the same substrate. In the disclosure, material including silicon and nitrogen is selectively deposited on a first surface of a substrate relative to a second surface of the same substrate by a cyclic deposition process by providing a substrate in a reaction chamber, providing a silicon precursor comprising silicon and halogen into the reaction chamber in a vapor phase and providing a nitrogen precursor into the reaction chamber in a vapor phase to form the material including silicon and nitrogen on the first surface.

  • Publication number: 20230098114
    Abstract: The present disclosure relates to methods and apparatuses for the manufacture of semiconductor devices. More particularly, the disclosure relates to methods and apparatuses for depositing an organic layer selectively on a substrate comprising at least two different surfaces. The process comprises providing a substrate in a reaction chamber, providing a first vapor-phase precursor in the reaction chamber, and providing a second vapor-phase precursor in the reaction chamber. In the method, the first and second vapor-phase precursors form the organic material selectively on the first surface relative to the second surface, and the first vapor-phase precursor comprises a diamine compound comprising at least five carbon atoms and the amine groups being attached to non-adjacent carbon atoms.
