  • Publication number: 20230077895
    Abstract: Disclosed in some embodiments is a chamber component (such as an end effector body) coated with an ultrathin electrically-dissipative material to provide a dissipative path from the coating to the ground. The coating may be deposited via a chemical precursor deposition to provide a uniform, conformal, and porosity free coating in a cost effective manner. In an embodiment wherein the chamber component comprises an end effector body, the end effector body may further comprise replaceable contact pads for supporting a substrate and the contact surface of the contact pads head may also be coated with an electrically-dissipative material.

  • Publication number: 20220351960
    Abstract: Methods and precursors for depositing metal fluoride films on a substrate surface are described. The method includes exposing the substrate surface to a metal precursor and a fluoride precursor. The fluoride precursor is volatile at a temperature in a range of from 20° C. to 200° C. The metal precursor reacts with the fluoride precursor to form a non-volatile metal fluoride film.

  • Patent number: 11390947
    Abstract: A method of forming a fluorinated metal film is provided. The method includes positioning an object in an atomic layer deposition (ALD) chamber having a processing region, depositing a metal-oxide containing layer on an object using an atomic layer deposition (ALD) process, depositing a metal-fluorine layer on the metal-oxide containing layer using an activated fluorination process, and repeating the depositing the metal-oxide containing layer and the depositing the metal-oxide containing layer until a fluorinated metal film with a predetermined film thickness is formed. The activated fluorination process includes introducing a first flow of a fluorine precursor (FP) to the processing region. The FP includes at least one organofluorine reagent or at least one fluorinated gas.
