YieldStar S 100 Overlay Measurement
Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
How it works
General reference — not yet source-verifiedOverlay measurement tools compare the registration of a newly patterned layer with the registration of a previously patterned layer on the same wafer.
The comparison is made using small target marks that are printed into both layers during exposure.
Where it fits in the process flow
General reference — not yet source-verifiedOverlay measurement is performed after a resist layer has been exposed and developed, before the pattern is transferred into the underlying film.
The measured wafers are normally a sample drawn from a production lot rather than the entire lot.
Applications
General reference — not yet source-verifiedOverlay measurement is used to monitor and control pattern alignment during integrated circuit fabrication.
The technique supports multiple patterning schemes, where a single device layer is defined by more than one lithography exposure.
