The SUSS Mask is a mask aligner used for photolithography. The SUSS Mask transfers patterns from photomasks onto photoresist-coated substrates using UV light. The SUSS Mask supports exposure wavelengths from 365nm to 405nm.[1]

Mask Cleaner[2]

What it is

General reference — not yet source-verified

A mask cleaner is a wet-processing cleanroom tool used to remove contamination from photomasks. Mask cleaners support lithography by preparing masks for use in exposure equipment and by helping maintain pattern fidelity during repeated process use.

How it works

General reference — not yet source-verified

Mask cleaning tools generally apply chemical cleaning steps to the mask surface in a controlled clean environment. Mask cleaning tools are used to dislodge particles, remove residues, and rinse away process contaminants without altering the intended mask pattern.

Where it fits in the process flow

General reference — not yet source-verified

Mask cleaning sits in the lithography support flow around mask handling, inspection, and exposure preparation. Mask cleaning is typically performed before mask use when contamination is present and after process use when residues or particles must be removed prior to storage, inspection, or reuse.

Applications

General reference — not yet source-verified

Mask cleaners are used in microfabrication environments that rely on photomasks for pattern transfer. Mask cleaners support semiconductor, photonics, MEMS, and related cleanroom patterning work by helping keep masks free of particles and chemical residues.
