  • Patent number: 10988718
    Abstract: A removal composition and process for cleaning post-chemical mechanical polishing (CMP) contaminants and particles from a microelectronic device having said particles and contaminants thereon. The removal compositions include at least one at least one organic additive; at least one metal chelating agent; and at least one polyelectrolyte. The composition achieves highly efficacious removal of the particles and CMP contaminant material from the surface of the microelectronic device without compromising the low-k dielectric, silicon nitride, and metal containing layers such as tungsten-containing layers.
    Type: Grant
    Filed: March 9, 2017
    Date of Patent: April 27, 2021
    Assignee: ENTEGRIS, INC.
    Inventors: Thomas Parson, Shrane-Ning Jenq, Steven Medd, Daniela White, Michael White, Donald Frye
  • Patent number: 10557107
    Abstract: A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions are substantially devoid of alkali hydroxides, alkaline earth metal hydroxides, and tetramethylammonium hydroxide. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.
