Start with roughness and stiffness spread before drawing a bonding-readiness band.

Mechanical readiness is a metrology question first.
Packaging / Test / Reliability
Hybrid bonding cannot be taught only as a packaging buzzword. Roughness, stiffness spread, particles, metrology sigma, and reliability evidence all have to stay visible.
EVIDENCE SEQUENCE
What the learner should inspect first.
This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.
Add particle state and metrology sigma so the band does not look absolute.

Inspect run card ->METHODS
Precomputed model contract.
The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.
AFM-like roughness and mechanical-spread teaching model.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
Readiness index penalizes contact risk and measurement uncertainty.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
Bands are evidence states for study planning, not manufacturing criteria.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
LIMITS
Useful, but deliberately bounded.
No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.
No NIST image, article text, proprietary package data, bonding recipe, or qualification limit.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
No product package selection or reliability qualification.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
Real use needs measured roughness maps, mechanical characterization, overlay context, defect review, bonding trials, and reliability evidence.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
SOURCE ANCHOR
Link-only public source spine.
SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
