What it is
How it works
General reference — not yet source-verifiedA lithography scanner transfers a circuit pattern from a mask or reticle onto a wafer using an optical exposure system.
A scanner in this class supports patterned exposure as part of photolithography processing in semiconductor manufacturing.
Where it fits in the process flow
General reference — not yet source-verifiedA lithography scanner sits in the wafer patterning flow between wafer preparation and later pattern transfer steps.
A lithography scanner is used before etching, implantation, or other downstream steps that rely on a resist image.
Applications
The ASML Twinscan 1200 B is used for semiconductor lithography.[2]
Why won't it start?
Documented failure modes, common issues, and field considerations.
- Non-operational due to internal water leak near lens
- No lens data available
