Abstract:
A method may include, but is not limited to, receiving a measurement including a metrology parameter for a layer of a metrology target and an alignment mark from an overlay metrology tool prior to a lithography process; deriving a merit figure from the metrology parameter and the alignment mark; deriving a correction factor from the merit figure; providing the correction factor to the lithography process via a feed forward process; receiving an additional measurement including an additional metrology parameter for the layer and an additional layer from an additional overlay metrology tool after the lithography process; deriving an adjustment from the additional metrology parameter; and providing the adjustment to the lithography process via a feedback process.

Claim (Index 11):
A system comprising:\n an overlay metrology tool configured to measure a metrology parameter for a layer of a metrology target and an alignment mark prior to a lithography process; an additional overlay metrology tool configured to measure an additional metrology parameter for the layer and an additional layer of the metrology target after the lithography process; and at least one control unit configured to:\n receive the measurement including the metrology parameter for the layer and the alignment mark from the overlay metrology tool prior to the lithography process; \n derive a merit figure from the metrology parameter and the alignment mark; \n derive a correction factor from the merit figure; \n provide the correction factor to the lithography process via a feed forward process; \n receive the additional measurement including the additional metrology parameter for the layer and the additional layer from the additional overlay metrology tool after the lithography process; \n derive an adjustment from the additional metrology parameter; and \n provide the adjustment to the lithography process via a feedback process.
