What it is
How it works
General reference — not yet source-verifiedOverlay measurement systems operate by optically imaging dedicated overlay targets that are printed on the wafer during lithography. The tool captures images of these targets at multiple sites and computes the relative displacement between the current layer and the underlying layer.
Where it fits in the process flow
General reference — not yet source-verifiedOverlay measurement is typically performed after the resist has been exposed and developed, before the pattern is transferred by etch. Overlay data is fed back to the lithography cell to adjust the exposure tool settings, improving alignment for subsequent wafers.

Frequently asked questions
What is the typical measurement principle used in this class of overlay system?General reference — not yet source-verified
Overlay measurement systems generally use optical imaging of dedicated targets (box-in-box, frame-in-frame, or advanced AIM targets) to determine the relative displacement between two layers. Bright-field or dark-field microscopy combined with sub-pixel resolution image analysis is the most common approach.
How often does an overlay tool need to be calibrated or maintained?General reference — not yet source-verified
Calibration frequency depends on the tool's stability and the fab's process control requirements; typical preventive maintenance includes periodic reference wafer measurements, optical system alignment checks, and environmental condition monitoring to ensure long-term repeatability.
Can this class of tool measure overlay on product wafers or only on test wafers?General reference — not yet source-verified
Modern overlay measurement systems are designed for both product wafers (using in-die targets) and test wafers. In-line metrology on product wafers provides real-time process feedback without requiring separate monitor wafers.
