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.
