  • Publication number: 20240383093
    Abstract: Embodiments of the present disclosure relate a CMP tool and methods for planarization a substrate. Particularly, embodiments of the present disclosure provide a substrate transporter for use in a CMP tool. The transporter may be used transport and/or carry substrates among various polishers and cleaners in a CMP tool while preventing the substrates from drying out during transportation. By keeping surfaces of the substrates wet during substrate waiting time or idle time in the CMP tool, embodiments of the present disclosure prevent many types of defects, such as byproducts, agglomerated abrasives, pad debris, slurry residues, from accumulate on the substrate surface during CMP processing, thus improve yields and device performance.

  • Publication number: 20240363361
    Abstract: A semiconductor processing tool includes a cleaning chamber configured to perform a post-chemical mechanical polishing/planarization (post-CMP) cleaning operation in an oxygen-free (or in a near oxygen-free) manner. An inert gas may be provided into the cleaning chamber to remove oxygen from the cleaning chamber such that the post-CMP cleaning operation may be performed in an oxygen-free (or in a near oxygen-free) environment. In this way, the post-CMP cleaning operation may be performed in an environment that may reduce oxygen-causing corrosion of metallization layers and/or metallization structures on and/or in the semiconductor wafer, which may increase semiconductor processing yield, may decrease semiconductor processing defects, and/or may increase semiconductor processing quality, among other examples.
