What it is
The Nikon 204 B is a lithography scanner.[1]
How it works
General reference — not yet source-verifiedA lithography scanner transfers a patterned image from a mask or reticle onto a photoresist-coated substrate by controlled optical exposure and alignment.
A scanner in this class typically aligns the mask pattern to the wafer, exposes selected fields, and repeats the exposure sequence across the substrate.
Where it fits in the process flow
General reference — not yet source-verifiedA lithography scanner sits in the patterning portion of semiconductor fabrication.
A lithography scanner follows resist preparation and alignment steps and precedes resist development and subsequent pattern-transfer steps.
Applications
General reference — not yet source-verifiedA lithography scanner is used to define circuit patterns on semiconductor wafers.
A lithography scanner is used wherever repeated optical pattern transfer is needed in microfabrication.
