  • Publication number: 20250232959
    Abstract: Some implementations described herein provide a deposition tool and methods of operation. The deposition tool may be used in the fabrication of integrated circuit devices to deposit materials and/or layers on a semiconductor substrate. The deposition tool may include a chamber (e.g., a processing chamber) that is coated with a dielectric coating on sidewalls of the chamber. The dielectric coating on the sidewalls of the chamber within the deposition tool increases a likelihood of a negative charge accumulating near the sidewalls of the chamber. The increased likelihood of negative charge accumulation near the sidewalls of the chamber may improve a uniformity of an electromagnetic field within the deposition tool (e.g., during a deposition operation) relative to another deposition too not including such a dielectric coating. The improved uniformity of the electromagnetic field may enable an improved uniformity of a material being deposited by the deposition tool to be achieved.

  • Publication number: 20240332026
    Abstract: A substrate grinding tool is configured to remove material from a semiconductor substrate in a grinding operation. In the grinding operation, the substrate grinding tool uses a combination of mechanical grinding and a chemical etchant to remove material from the semiconductor substrate. The chemical etchant may be heated to a high temperature, which may increase the etch rate of the chemical etchant. The use of the combination of mechanical grinding and the chemical etchant may increase the grinding rate of the substrate grinding tool for grinding semiconductor substrates, may reduce surface roughness for semiconductor substrates that are processed by the substrate grinding tool, and/or may reduce surface damage for semiconductor substrates that are processed by the substrate grinding tool, among other examples.
