  • Publication number: 20220384197
    Abstract: The current disclosure relates to deposition of a transition metal chalcogenide barrier layer. The method of depositing a transition metal chalcogenide barrier layer comprises providing a substrate having an opening into a reaction chamber, providing a transition metal precursor in the reaction chamber in vapor phase and providing an reactive chalcogen species in the reaction chamber. The method may be a plasma-enhanced atomic layer deposition method. The disclosure further relates to an interconnect comprising a transition metal chalcogenide barrier layer.

  • Publication number: 20210025059
    Abstract: Plasma atomic layer deposition (ALD) is optimized through modulation of the gas residence time during an excited species phase, wherein activated reactant is supplied such as from a plasma. Reduced residence time increases the quality of the deposited layer, such as reducing wet etch rates, increasing index of refraction and/or reducing impurities in the layer. For example, dielectric layers, particularly silicon nitride films, formed from such optimized plasma ALD processes have low levels of impurities remaining from the silicon precursor.
