Quickstart
Get from a loaded lot to a saved notebook with one clear finding.
Recommended first pass
Section titled “Recommended first pass”- Open
Analyzeand select a lot. - Wait for the default snapshot and test context to load.
- Scan the CPK table for the worst tests.
- Open scatter, histogram, or wafer views from the failing test.
- Brush a region or die population and watch the other views update.
- If you need to evaluate a limit change, enter what-if mode and review impact before saving.
- If you need a custom table or grouped summary, switch to
SQL— your current lot and selection carry over automatically. - Save the notebook when you have a finding worth keeping.
What to look for first
Section titled “What to look for first”- low CPK tests with non-trivial fail rate
- spatial signatures on the wafer map
- outlier tails in histogram
- site or wafer-specific behavior in scatter and trend views
- large differences between baseline and proposed yield in impact review
Key concepts
Section titled “Key concepts”Lot selectorchooses the dataset.Snapshot selectorchooses the saved ingest state for that lot.- cards give a fast view.
- modals give the full interaction model.
- notebook state persists analysis context, selection state, and scenario limits.
- SQL inherits your analysis context automatically.
Remember
Section titled “Remember”- linked views share the same analysis context
- what-if limit edits are saved in notebook state
- share links are read-only
- saved versions track the version they were based on
