  • Publication number: 20260136879
    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, a method includes using an extended spectroscopic ellipsometer to direct a beam of electromagnetic radiation having a beam energy toward a portion of a substrate at an incident angle to produce an extended spectroscopic ellipsometry (ESE) data set from the portion of the substrate which includes a measured change of a phase and/or an amplitude of the beam of electromagnetic radiation reflecting away from the portion of the substrate relative to the beam of electromagnetic radiation directed toward the portion of the substrate. One or more properties of the portion of the substrate are then determined based at least in part on the ESE data set of the portion of the substrate.

  • Patent number: 11626288
    Abstract: Methods for reducing interface resistance of semiconductor devices leverage dual work function metal silicide. In some embodiments, a method may comprise selectively depositing a metal silicide layer on an Epi surface and adjusting a metal-to-silicon ratio of the metal silicide layer during deposition to alter a work function of the metal silicide layer based on whether the Epi surface is a P type Epi surface or an N type Epi surface to achieve a Schottky barrier height of less than 0.5 eV. The work function for a P type Epi surface may be adjusted to a value of approximately 5.0 eV and the work function for an N type Epi surface may be adjusted to a value of approximately 3.8 eV. The deposition of the metal silicide layer on the Epi surface may be performed prior to deposition of a contact etch stop layer and an activation anneal.
