Gyroscope
Bond and package a gyroscope-mems-die with a separate readout ASIC and controlled cavity; calibration limits and phone compatibility remain unproven Discovery hypothesis; target capability is unverified.

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
- Bond and package a gyroscope-mems-die with a separate readout ASIC and controlled cavity; calibration limits and phone compatibility remain unproven
- 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.
- Selected wirebond package hypothesis does not establish flagship I/O density, power delivery, size or thermal capability; flip-chip bump/underfill architecture is a separate OR alternative requiring its own complete inventory.
- Release, protective capping, feedthrough formation and singulation order is unresolved; exposing released movable structures during wet dicing may be incompatible. Capping may need to precede dicing. Cavity pressure must be selected for the actual damping/acoustic demand, not universally vacuum.
