What it is
How it works
General reference — not yet source-verifiedMask cleaners in this class use wet chemical and rinse sequences to remove particles, residues, and contaminants from the surfaces of photomasks or reticles.
Cleaning typically involves immersion or spray application of cleaning solutions, followed by rinsing and drying, to restore mask cleanliness without damaging the patterned surface.
Where it fits in the process flow
General reference — not yet source-verifiedThe Ultratech 602 Plate Mask Cleaner is used in the photomask manufacturing and wafer fab flow to clean photomasks and reticles between uses or after storage.
Upstream processes include photomask fabrication or photolithography, where masks become contaminated. Downstream, cleaned masks are returned to exposure tools such as steppers or scanners for use in wafer patterning.
Applications
General reference — not yet source-verifiedThe Ultratech 602 Plate Mask Cleaner is applied in semiconductor photolithography for cleaning photomasks and reticles used in optical lithography systems.
The machine handles plate-type and mask-type substrates, making it suitable for cleaning in advanced-node and legacy fab environments alike.
