Start with post-lithography CD bin, overlay signature, resist state, and focus bucket.
Open the run card to inspect the saved rows, methods, limits, and export files behind this step.
Inspect run card ->LESSON PACKET / SA-PROC-CTRL-001
Connect lithography measurements to etch and yield evidence.
Process / Metrology / Yield
The useful lesson is not a recipe. It is how post-lithography CD and overlay evidence can feed a downstream etch hypothesis, then move Cpk-style and circuit-delay proxies with visible boundaries.
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.
Compare feedforward action classes against post-etch CD, Cpk proxy, defect-risk proxy, and delay proxy.
Open the run card to inspect the saved rows, methods, limits, and export files behind this step.
Inspect run card ->Route the next evidence check to operator, engineer, integration, or yield view before making a claim.
Open the run card to inspect the saved rows, methods, limits, and export files behind this step.
Inspect run card ->METHODS
Precomputed model contract.
The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.
Original synthetic process-control table based on public feedforward and metrology vocabulary.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
No scanner setting, etch setting, SEMulator3D project, article content, or commercial tool file is copied.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
The browser filters saved CSV rows and exposes the model card with public boundaries.
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 process recipe, gas ratio, tool setting, equipment control, rework instruction, or qualification workflow.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
Cpk and delay values are teaching proxies, not measured wafer or product evidence.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
Real work needs owned metrology, uncertainty budget, process-owner review, and quality governance.
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.
