Ordered evidence chain

Follow each handoff. Stop at the stop.

Node order and edge fields are fixed by the V123 contract. No page interaction generates, ranks, or extends this chain.

  1. Process / geometry

    Thermal budget state

    RTA, spike, and furnace artifacts expose normalized thermal states without an equipment program.

    Status
    Bridge
    Assumption
    The Arrhenius-style axes and coefficients are educational and not material, dopant, or equipment calibration.
    Bridge condition
    Compare only the fixed modes and keep the no-recipe boundary attached.
    Limitation
    No temperature-time program, ramp, ambient, wafer thermal history, dopant profile, stress, or physical activation measurement is included.
    Measured replacement slot
    Owned temperature trace, implant/material context, sheet resistance, SIMS or spreading-resistance profile, uncertainty, and equipment genealogy.
  2. Material / interface

    Activation / diffusion balance

    The public replay separates activation benefit and diffusion burden as teaching proxies.

    Status
    Bridge
    Assumption
    The interactive chain uses original fixed coefficients rather than calibrated process-device simulation.
    Bridge condition
    Use only as a sensitivity map under the displayed chain states.
    Limitation
    No junction geometry, dopant species, interface state, mobility model, compact-model extraction, or measured device split closes the bridge.
    Measured replacement slot
    Matched thermal split with sheet resistance, junction profile, Id-Vg, capacitance, leakage, and uncertainty on registered structures.
  3. Device metric

    Rs / Vt sensitivity

    The chain maps thermal-state proxies into sheet-resistance and threshold-related device questions.

    Status
    Bridge
    Assumption
    The chain and FO4 artifacts are bounded proxies with separate model assumptions and no timing-library correlation.
    Bridge condition
    Retain supply, load, temperature, model, and extraction boundaries when comparing states.
    Limitation
    No characterized cell library, extracted interconnect, PVT matrix, self-heating, aging, variation, or silicon ring-oscillator correlation is included.
    Measured replacement slot
    Calibrated compact model and characterized FO4 or ring-oscillator structures across PVT, load, extraction, variation, and uncertainty.
  4. Circuit behavior

    FO4 delay sensitivity

    The browser chain frames a bounded delay response and does not represent Liberty or silicon timing.

    Status
    Stop
    Assumption
    No V122 artifact provides direct measured genealogy from thermal split through timing to product outcome.
    Bridge condition
    Stop before process-window, Vmin, reliability, yield, disposition, or qualification statements.
    Limitation
    A deterministic delay proxy cannot establish manufactured distribution tails or causal attribution.
    Measured replacement slot
    Lot-wafer-die thermal genealogy, device/circuit measurements, array Vmin or timing, reliability, test coverage, yield labels, uncertainty, and owner review.
  5. Evidence stop

    Stop before Vmin or yield

    No public measured chain links anneal conditions to product timing, SRAM Vmin, reliability, or yield.

Path boundary

This path does not prove causality.

The navigator presents curated associations, assumptions, evidence classes, and replacement needs. It does not prove physical or statistical causality.

A stop is a product requirement, not missing UI. The page must not fill a stopped bridge with extrapolation, AI text, a recipe, an equipment setting, or an operating recommendation.

No public path authorizes process changes, equipment control, wafer disposition, qualification, signoff, product ranking, or production release.
