Making outline

Deposit polysilicon from purified trichlorosilane in a Siemens-type reactor, then break, clean and assay stock for semiconductor use
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

Making route and target-level requirements not researched.
Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.

Unselected discovery proposals

These are research questions, not published manufacturing dependencies. The seed combines alternatives, operating requirements and verification relationships.
