PURPOSE
    Define a formal AI-readable ontology for Microelectronics, including
    semiconductor materials, microfabricated devices, transistors,
    integrated circuits, process technologies, lithography, doping,
    deposition, etching, oxidation, interconnects, contacts, vias, device
    scaling, parasitics, analogue, digital and mixed-signal blocks,
    process-voltage-temperature variation, packaging, testing, yield,
    reliability, provenance, uncertainty, confidence and recursive
    microelectronics reasoning.

    Critical Distinction
        Microelectronics reasoning must distinguish process-node labels
        from exact physical dimensions, feature size from complete device
        geometry, designed dimensions from fabricated dimensions and
        fabrication yield from long-term reliability. Process versions,
        mask revisions, wafer, lot and die provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Microelectronics combines semiconductor physics, device engineering,
    circuit design and microfabrication to create microscopic electronic
    devices and integrated circuits. Reliable reasoning preserves process
    and mask revisions, wafer, lot and die identity, designed and measured
    geometry, doping, films, interconnects, parasitics, process conditions
    and test provenance while distinguishing process-node terminology from
    exact dimensions and fabrication yield from long-term reliability.
