    摘要: Method for operating a processing system and refurbishing a ceramic substrate holder within a process chamber of the processing system are described. The method includes plasma processing one or more substrates on the ceramic substrate holder, where the processing causes erosion of a nitride material of the ceramic substrate holder. The method further includes refurbishing the ceramic substrate holder in-situ without a substrate residing on the ceramic substrate holder, where the refurbishing includes exposing the ceramic substrate holder to a plasma-excited nitrogen-containing gas in the process chamber to at least partially reverse the erosion of the nitride material.

    摘要: A method for forming a modified TaC or TaCN film that may be utilized as a barrier film for Cu metallization. The method includes disposing a substrate in a process chamber of a plasma enhanced atomic layer deposition (PEALD) system configured to perform a PEALD process, depositing a TaC or TaCN film on the substrate using the PEALD process, and modifying the deposited TaC or TaCN film by exposing the deposited TaC or TaCN film to plasma excited hydrogen or atomic hydrogen or a combination thereof in order to remove carbon from at least the plasma exposed portion of the deposited TaCN film. The method further includes forming a metal film on the modified TaCN film, where the modified TaCN film provides stronger adhesion to the metal film than the deposited TaCN film. According to one embodiment, a TaCN film is deposited from alternating exposures of TAIMATA and plasma excited hydrogen.

    摘要: A method for integrating metal-containing cap layers into copper (Cu) metallization of semiconductor devices. In one embodiment, the method includes providing a patterned substrate containing Cu metal surfaces and dielectric layer surfaces, forming a patterned mask layer on the patterned substrate, where the patterned mask layer contains openings that expose the Cu metal surfaces. The method further includes depositing a metal-containing layer on the Cu metal surfaces, depositing an additional metal-containing layer on the patterned mask layer, and removing the patterned mask layer and the additional metal-containing layer from the patterned substrate to selectively form metal-containing cap layers on the Cu metal surfaces.

    摘要: A high conductance, multi-tray film precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing the deposition rate by increasing exposed surface area of film precursor. The multi-tray film precursor evaporation system includes one or more trays. Each tray is configured to support and retain film precursor in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel within the stackable trays and through an outlet in the solid precursor evaporation system.
