Making outline
- Deposit and pattern thin polysilicon routing/fixed electrodes on the isolated substrate
- Build or acquire each explicit earlier physical input; establish independent references and interfaces.
- Make trials and accept only against the eventual caller specification; record uncertainty and rejected outputs.
What remains unresolved
- Full inventory, required quantities, process settings, numerical demand and suitability remain open.
