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
- Apply a analog CMOS process hypothesis to blank wafers using deposition, patterning, doping, etch, cleaning and interconnect stages
- 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
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
