  • Publication number: 20230317445
    Abstract: Semiconductor processing methods and apparatuses are provided. Some methods include providing a first wafer to a processing chamber, the first wafer having a thickness, a beveled edge, a first side, and a plurality of devices formed in a device area on the first side, the device area having an outer perimeter, depositing an annular ring of material on the first wafer, the annular ring of material covering a region of the beveled edge and the outer perimeter of the device area, and having an inner boundary closer to the center point of the first wafer than the outer perimeter, bonding a second substrate to the plurality of devices and to a portion of the annular ring of material, and thinning the thickness of the first wafer.

  • Patent number: 10400323
    Abstract: A method for removing and preventing defects on surfaces of a component of a substrate processing chamber includes loading the component into a vacuum chamber and, with the component loaded within the vacuum chamber, baking the component at a baking temperature during a first predetermined period to remove water and defects from the surfaces of the component, and purging the component within the vacuum chamber during at least one second predetermined period to remove the defects from the vacuum chamber.
    Type: Grant

  • Publication number: 20180294197
    Abstract: A method for testing cleanliness of a component of a substrate processing chamber includes loading the component into a vacuum chamber, arranging a test substrate within the vacuum chamber, with the component and the test substrate loaded within the vacuum chamber, providing a purge gas to the vacuum chamber, determining at least one of an amount of particles accumulated on the test substrate and an amount of metal contamination accumulated on the test substrate caused by providing the purge gas to the vacuum chamber, and estimating the cleanliness of the component based on the at least one of the determined amount of particles accumulated on the test substrate and the determined amount of metal contamination accumulated on the test substrate.

  • Patent number: 7335462
    Abstract: A method of forming an integrated circuit using an amorphous carbon film. The amorphous carbon film is formed by thermally decomposing a gas mixture comprising a hydrocarbon compound and an inert gas. The amorphous carbon film is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the amorphous carbon film is used as a hardmask. In another integrated circuit fabrication process, the amorphous carbon film is an anti-reflective coating (ARC) for deep ultraviolet (DUV) lithography. In yet another integrated circuit fabrication process, a multi-layer amorphous carbon anti-reflective coating is used for DUV lithography.
