  • Patent number: 11062942
    Abstract: Methods of etching a metal layer and a metal-containing barrier layer to a predetermined depth are described. In some embodiments, the metal layer and metal-containing barrier layer are formed on a substrate with a first dielectric and a second dielectric thereon. The metal layer and the metal-containing barrier layer formed within a feature in the first dielectric and the second dielectric. In some embodiments, the metal layer and metal-containing barrier layer can be sequentially etched from a feature formed in a dielectric material. In some embodiments, the sidewalls of the feature formed in a dielectric material are passivated to change the adhesion properties of the dielectric material.

  • Patent number: 8722534
    Abstract: A method for forming an interconnect structure includes forming a recess in a dielectric layer of a substrate, forming a first transition metal layer in the recess on corner portions of the recess, and forming a second transition metal layer in the recess over the first transition metal layer to line the recess. The method further includes filling the recess with a fill layer and annealing the substrate so that the first transition metal layer and the second transition metal layer form an alloy portion proximate the corner portions during the annealing, the alloy portion having a reduced wettability for a material of the fill layer than the second transition metal. Additionally, the method includes polishing the substrate to remove portions of the fill layer extending above the recess.

  • Patent number: 7157371
    Abstract: A dielectric barrier layer composed of a metal oxide is applied in thin layers with a thickness of less than 20 nanometers in the course of processing semiconductor devices by sequential gas phase deposition or molecular beam epitaxy in molecular individual layers on differently structured base substrates. The method allows, inter alias, effective conductive diffusion barriers to be formed from a dielectric material, an optimization of the layer thickness of the barrier layer, an increase in the temperature budget for subsequent process steps, and a reduction in the effort for removing the temporary barrier layers.
