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
- Slice, edge-shape, lap, etch, polish, clean and inspect a wafer from a single-crystal ingot; final wafer specification is open
- Develop a bounded process specification and establish earlier availability of every listed physical prerequisite.
- Make trial pieces, measure interfaces and performance with independently established references, and reject incompatible outputs.
What remains unresolved
- Identified requirement; no researched making route or qualified output yet.
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
