NSR S 203 B
What it is
The Nikon NSR S 203 B is a semiconductor lithography stepper or scanner used for photolithography on 8-inch wafers.[2][3][6]
How it works
General reference — not yet source-verifiedA lithography stepper or scanner projects a patterned image through an optical system onto a photoresist-coated wafer. The exposure transfers circuit patterns in repeated fields across the wafer, using precise alignment and focus control to define features for later etch or deposition steps.
Where it fits in the process flow
General reference — not yet source-verifiedThis machine sits in the front end of semiconductor manufacturing, after wafer preparation and photoresist coating and before pattern transfer steps such as etching or implantation. Its role is to create the patterned resist image that defines the next process level.
Applications
General reference — not yet source-verifiedThis type of lithography tool is used for photolithographic patterning in semiconductor device fabrication, where a resist image is formed on the wafer before subsequent pattern transfer.

Frequently asked questions
What kind of equipment is the Nikon NSR S 203 B?General reference — not yet source-verified
It is a lithography system used to transfer circuit patterns onto a photoresist-coated substrate.
What does a lithography system do in semiconductor manufacturing?General reference — not yet source-verified
It exposes selected areas of photoresist with a patterned optical image so later process steps can form the desired circuit geometry.
Where is this class of machine used in the process flow?General reference — not yet source-verified
It is used during patterning, after resist coating and before development and downstream material-removal or material-formation steps.
Why is alignment important for this class of tool?General reference — not yet source-verified
Alignment ensures that each new patterned layer is placed correctly relative to previously formed structures on the wafer.
What kinds of structures are made with this class of equipment?General reference — not yet source-verified
It is used to define fine features that become semiconductor devices, interconnects, and other precision patterned elements.
