What it is
How it works
General reference — not yet source-verifiedAn overlay measurement system compares the alignment of patterned layers on a wafer against intended placement.
Overlay metrology supports process control by measuring registration error after lithographic exposure and pattern transfer steps.
Where it fits in the process flow
General reference — not yet source-verifiedAn overlay measurement tool is used after patterning steps to verify layer-to-layer alignment before downstream processing continues.
