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.

Making outline
- Prepare filtered aqueous TMAH solution for selected positive-resist development
- Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.
What remains unresolved
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
- Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
- Concentration and resist/process compatibility unknown; this route excludes dry development.
