What it is
General reference — not yet source-verifiedThe KLA Archer AIM+ is an overlay metrology system used in semiconductor manufacturing. Overlay metrology measures the alignment accuracy between successive patterned layers on a wafer, a critical parameter for device yield and performance. Such systems employ optical imaging to capture overlay targets printed on the wafer and compute registration errors.
Where it fits in the process flow
General reference — not yet source-verifiedOverlay metrology systems such as the Archer AIM+ are positioned in the fab flow after the lithography and develop steps but before the etch process. After a photoresist layer has been exposed and developed, the overlay measurement verifies that the printed pattern aligns correctly with the underlying layers. If overlay errors exceed process specifications, the lot may be reworked (stripped and re-exposed) or process parameters adjusted upstream. The measurement data is fed back to the lithography track and scanner to drive corrections.
