  • Patent number: 11459651
    Abstract: Embodiments of a tantalum (Ta) target pasting process for deposition chambers using RF powered processes include pasting at least a portion of the inner surfaces of the process chamber with Ta after using RF sputtering to deposit dielectric material on a wafer. Pressure levels within the process chamber are adjusted to maximize coverage of the Ta pasting layer. The Ta pasting encapsulates the dielectric material that has been inadvertently sputtered on the process chamber inner surfaces such as the shield. Oxygen is then flowed into the process chamber to form a tantalum oxide layer on the Ta pasting layer to further reduce contamination and particle generation.
