Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Complete inventory, selected process and compatible quantitative capability remain open. Unselected because electronics/power/control/calibration availability may form a self-supporting manufacturing cycle; no earlier capability tier is established.
Making outline
- Build manually addressed DUV projection apparatus with mechanical stage/shutter/source controls and separately made reference-reticle writing fixture
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- No high-end phone chip process, layout, material purity, resolution/overlay budget or complete fab route is specified.
- DUV lens architecture is not EUV; EUV requires reflective optics and vacuum.
- Teaching exposure cannot be substituted for advanced smartphone fabrication without meeting the actual specification.
- Machine control/computing, optics, masks, clean utilities and calibration bootstrap remain unresolved.
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
- Current memory-first method needs source and compatibility review.
