Publication integrity record

Substrate processing apparatus

This page is the evidence record. It changes as evidence arrives: a trusted timestamp, an independent retrieval, a custody deposit. The disclosure itself (/p/OT-2026-000002087) never changes.

A capture held by an outside archive is evidence that does not depend on OpenTechnical continuing to exist. It supplements the records above; it does not replace them.
