  • Patent number: 12237216
    Abstract: A method for filling recessed features with a low-resistivity metal. The method includes providing a patterned substrate containing a recessed feature formed in a first layer and a second layer that is exposed in the recessed feature, forming a nucleation enhancement layer on a sidewall of the first layer in the recessed feature and depositing a metal layer in the recessed feature by vapor phase deposition, where the metal layer is deposited on the second layer and on the nucleation enhancement layer. An initial metal layer may be selectively formed on the second layer in the recessed feature before forming the nucleation enhancement layer.
