  • Publication number: 20240087955
    Abstract: A method and apparatus for forming tungsten features in semiconductor devices is provided. The method includes exposing a top opening of a feature formed in a substrate to a physical vapor deposition (PVD) process to deposit a tungsten liner layer within the feature. The PVD process is performed in a first processing region of a first processing chamber and the tungsten liner layer forms an overhang portion, which partially obstructs the top opening of the feature. The substrate is transferred from the first processing region of the first processing chamber to a second processing region of a second processing chamber without breaking vacuum. The overhang portion is exposed to nitrogen-containing radicals in the second processing region to inhibit subsequent growth of tungsten along the overhang portion. The feature is exposed to a tungsten-containing precursor gas to form a tungsten fill layer over the tungsten liner layer within the feature.

  • Publication number: 20240088071
    Abstract: Methods for reducing resistivity of metal gapfill include depositing a conformal layer in an opening of a feature and on a field of a substrate with a first thickness of the conformal layer of approximately 10 microns or less, depositing a non-conformal metal layer directly on the conformal layer at a bottom of the opening and directly on the field using an anisotropic deposition process. A second thickness of the non-conformal metal layer on the field and on the bottom of the feature is approximately 30 microns or greater. And depositing a metal gapfill material in the opening of the feature and on the field where the metal gapfill material completely fills the opening without any voids.

  • Publication number: 20230018348
    Abstract: A vapor source system based on vapor-liquid ejector supercharging combined with flash vaporization technology belongs to the technical fields of waste heat utilization and steam generation. The system comprises a vapor-liquid ejector, a flash vaporization tank and a intermediate heat exchanger, wherein the vapor-liquid ejector uses high-pressure steam to raise temperature and pressure of low-pressure water absorbed from the flash vaporization tank; the pressure-increased water is flashed into low-pressure saturated steam after entering the flash vaporization tank; the saturated water which is not flashed is collected at the bottom of the flash vaporization tank.
