The Nikon Scanner 204 B is a lithography stepper manufactured by Nikon. The Nikon Scanner 204 B supports 6-inch and 8-inch wafers. The Nikon Scanner 204 B is specified at 0.15 µm.[1][2][3]
What it is
How it works
General reference — not yet source-verifiedA lithography stepper exposes photoresist in a repeated sequence of alignment and projection exposures across a wafer.
A stepper in this class uses a mask or reticle, precision wafer positioning, and optical reduction to transfer circuit patterns onto the resist-coated wafer.
Where it fits in the process flow
General reference — not yet source-verifiedA lithography stepper sits in the pattern-definition stage of semiconductor manufacturing.
The Nikon Scanner 204 B is used before downstream etch or deposition pattern transfer steps that follow resist patterning.
Applications
General reference — not yet source-verifiedThe Nikon Scanner 204 B is used for semiconductor photolithography on silicon wafers.
