3200 Wafer

A wafer cleaner is wet processing equipment used to remove residues, particles, and chemical films from wafer surfaces. Wafer cleaners are part of the cleaning segment of semiconductor manufacturing and are used to prepare wafers for later process steps or to restore surface condition after earlier fabrication steps.

Wafer cleaning equipment generally exposes wafer surfaces to controlled wet chemistries and rinse sequences to remove contamination and unwanted surface material. Wet cleaning tools commonly manage chemical delivery, process timing, rinsing, and transfer through enclosed process modules intended for repeatable wafer treatment.

Wafer cleaning tools are placed between contamination-generating process steps and surface-sensitive process steps. Wafer cleaning commonly appears before oxidation, diffusion, deposition, lithography, metrology, bonding, and inspection when a controlled surface condition is required.

Wet cleaning also appears after etch, strip, polish, and implant-related sequences when residues or films must be removed before the next module in the line. Wafer cleaning supports yield by reducing particles, chemical carryover, and surface contamination before downstream processing.

Wet wafer cleaning is used for preclean and post-process cleaning across semiconductor fabrication. Typical applications include removal of oxide, particles, organics, and metallic contamination from wafer surfaces before the next fabrication step.
