  • 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: 20230301506
    Abstract: The exemplified systems and methods disclosed herein involve the contemporaneous and concurrent stimulation of both eyes of a patient with dissimilar visual scenes that substantially span an expected or normal visual field of both eyes. During an assessment via the exemplified system and methods, a test eye (i.e., eye being assessed) is presented a visual scene that is rich in contours (e.g., a scene with rich texture patterns) that substantially span an expected or normal visual field of a person while the non-tested eye is presented an impoverished visual scene (e.g., a contour-free or non-distinguishing-contour scene, e.g., with a homogeneous color, with respect to the contour-rich scene). Defects in the visual field can be detected by assessing for breaks or discontinuity in the observation of the contour-rich scene by the person.
