Suitable for advanced lithography development and controlled pilot evaluation; production adoption requires model-specific qualification.

Why: Customer tests demonstrate working High-NA imaging and substantial pilot use. Public commercial milestones combine scanner generations, leaving EXE:5000 production yield and economics unresolved.
Next: Require EXE:5000-specific availability, layer yield, stitching performance and cost-per-good-wafer results before committing a production process.

Constraints

Very high equipment cost and uncertain savings relative to low-NA multipatterning.
Half-size exposure fields require stitching and associated design and alignment controls for larger dies.
Resists, masks, optical proximity correction and etch processes require coordinated qualification.
Public EXE:5000-specific sustained availability and commercial yield data remain limited.
Fleet-wide production milestones do not establish the EXE:5000’s individual production performance.
