Archer XT+ Overlay Measurement
What it is
How it works
General reference — not yet source-verifiedOverlay measurement tools compare patterned layers so a fab can evaluate alignment between successive process steps.
Where it fits in the process flow
General reference — not yet source-verifiedThe Archer XT+ is used after patterning steps that create the layers whose relative position must be checked.
