DCS 141 Wafer Cleaner Spin

Wafer cleaners and spin dryers are wet processing tools used to rinse, clean, and dry wafers after process steps that leave liquids or particles on the wafer surface. Spin drying generally removes liquid from the wafer by rotating the wafer so fluid is expelled from the surface while helping limit residual moisture.

Spin cleaning and spin drying tools generally hold a wafer on a rotating chuck or support and apply liquids during cleaning stages, followed by higher speed rotation for drying. Wet processing tools of this class are used to remove process residues and reduce water marks or retained liquid before the wafer moves to the next operation.

Wafer cleaning and spin drying tools are typically placed around wet process modules and inspection-sensitive steps where a wafer must be free of residual chemistry, rinse water, or loose contamination before further processing. Such tools commonly bridge process steps by preparing the wafer surface for handling, metrology, coating, bonding, or other downstream operations.

Wet wafer cleaning and spin drying are used where surface cleanliness and dry wafer presentation matter for yield and process stability. Typical uses include post-rinse drying, removal of loose particles, and preparation of wafers for subsequent fabrication or inspection steps.
