A wet processing cleaner removes residues, particles, and chemical contaminants from wafer surfaces. Wet cleaning tools are used between patterning, deposition, etch, and other module steps to prepare wafers for the next operation and to reduce defect carryover.

Wet processing cleaners move wafers through chemical and rinse stages that are intended to dislodge particles, dissolve unwanted films, and leave the surface ready for subsequent fabrication steps. Wet processing cleaners commonly combine automated wafer handling with enclosed process modules and load port interfaces for cassette or pod based transfer.

Wet cleaning tools are placed at repeated points across semiconductor manufacturing because surface preparation is needed before and after many unit processes. Wet cleaning commonly follows steps that can leave residues or particles, and wet cleaning commonly precedes steps that demand a well prepared surface for film growth, lithography, bonding, or inspection.

Wafer cleaners are used for front end and related clean processes where contamination control on the wafer surface is important. Wet cleaning supports particle removal, residue stripping, post process rinsing, and general wafer surface preparation for subsequent manufacturing operations.
