Process options and open questions

Unresolved metal, MIM, and resistor-option evidence and conflicts.

This page keeps unresolved fabrication-option statements separate from confirmed process and PDK facts.

Current summary

Confirmed process and PDK names are maintained on Process and PDK. This page only tracks option values that remain unresolved in the archive.

Open questions and conflicts

  • Open question — MIM and resistor: A Magic technology-file report assumed 1 kOhm/square high-res poly and 2 fF/um2 MIM. Leo Moser said the 2 fF value did not match the stack documentation he expected. (archive message; Discord)
  • Confirmed interpretation of the conflict: Tim Edwards explained that MIM capacitance and high-resistor values are process-form options. No layout marker identifies which option was selected. (archive message; Discord)
  • Open question — top metal: On 2026-07-06, Tim Ansell said wafer.space was unsure whether Run 1 had received 11 kA or 9 kA top metal. (archive message; Discord)
  • Community claim, not controlled fact: On 2026-08-06, tnt stated that Run 3 used 11 kA top metal, MIM Option B, 2 fF/um2, and 1 kOhm/square. tnt then said the answer came from prior Discord discussion, not the wafer.space site. (archive message; Discord) (archive message; Discord)

Curation decision

Do not publish a confirmed metal thickness, MIM density, or high-resistor value from these messages alone. A run-specific process form or another controlled wafer.space or GF source is required. Until then, tool defaults and community summaries are evidence of assumptions, not fabrication control. (archive message; Discord) (archive message; Discord) (archive message; Discord)
