Semi E36

SEMI E36 defines Equipment Manufacturing-Information Tagging, the standard that specifies how a tool's firmware, software modules, and configuration data must each carry machine-readable identification tags — version number, build date, part/revision identifier — so a host or a field engineer can programmatically verify exactly what's installed on a piece of equipment rather than relying on a label, a service log, or institutional memory. A modern fab tool is a composite of many independently versioned pieces — main control firmware, a recipe-management module, a vision-system package, a safety-interlock controller — and without a standard tagging scheme there's no reliable way for a host system to ask "what exact combination of software versions is actually running on this tool right now" and get a trustworthy answer back.

Tool contains multiple independently versioned components
Firmware, recipe module, vision package, safety controller
SEMI E36 manufacturing-information tagsEach component carries its own machine-readable identity
Version, build date, revision ID per component
Queryable, not just printed on a physical label
E36.1 specifies the tag format itself
Consistent structure every vendor's tooling can parse
Host confirms exact installed configuration
No ambiguity during audits, upgrades, or troubleshooting

E36.1's role is making sure these tags are useful across the whole fab rather than readable only by the vendor who wrote them: it defines a consistent tag structure so a host system integrating equipment from multiple vendors can parse manufacturing-information tags the same way regardless of source, instead of needing a custom parser per vendor's proprietary labeling convention. This becomes operationally important during any fleet-wide software audit or security patch rollout: a fab verifying that every tool of a given model has the same firmware version applied, or confirming which tools still run a vulnerable older build, depends entirely on E36's tags being both present and consistently formatted — a tool without proper E36 tagging turns what should be a quick automated query into a manual, tool-by-tool inspection.

SEMI E36 — Manufacturing-Information Tags every component, independently queryable and version-tagged One tool, multiple tagged components Main control firmware v4.2.1, built 2026-08-14 Recipe-management module v2.0.6, rev C Vision-system package v1.8.3, built 2026-06-02 Safety-interlock controller v3.1.0, rev A E36.1 defines the consistent tag structure parsed across all four A fleet-wide audit becomes one query instead of a tool-by-tool inspection Without it, confirming what's actually installed falls back to a label or a service log

E36 and E36.1 are the identity layer underneath every other equipment-communication standard in this family: SEMI E40's process-job state, E41's exceptions, and E42's recipes all assume a host can trust what software version is actually generating those messages, and that trust traces back to E36's tagging making the running configuration verifiable rather than assumed.
