Abstract: A method involving measuring a first metrology target designed for a first range of values of a process parameter; measuring a second metrology target designed for a second range of values of the same process parameter, the second range different than the first range and the second metrology target having a different physical design than the first metrology target; and deriving process window data from a value of the process parameter in the first range determined from the measuring of the first metrology target, and from a value of the process parameter in the second range determined from the measuring of the second metrology target.

Abstract: A method of adjusting speed and/or routing of a part of a movement plan of a table under an immersion fluid supply system of a lithographic apparatus. The method includes splitting the movement plan of the table into a plurality of discrete movements; determining a risk of a bubble of a size greater than a certain size being present in immersion fluid through which a patterned beam of the lithographic apparatus will pass during a certain discrete movement by determining whether the immersion fluid supply system passes over a position at which immersion fluid leaked from the immersion fluid supply system is present; and adjusting the speed and/or routing of a part of the movement plan corresponding to (i) a discrete movement earlier than a discrete movement for which the risk of a bubble is determined, and/or (ii) a discrete movement for which the risk of a bubble is determined.

Abstract: A method for optimizing a sequence of processes for manufacturing of product units, includes: associating measurement results of performance parameters (e.g., fingerprints) with the recorded process characteristics (e.g., context); obtaining a characteristic (e.g., context) of a previous process (e.g. deposition) in the sequence already performed on a product unit; obtaining a characteristic (e.g., context) of a subsequent process (e.g., exposure) in the sequence to be performed on the product unit; determining a predicted performance parameter (e.g., fingerprint) of the product unit associated with the sequence of previous and subsequent processes by using the obtained characteristics to retrieve measurement results of the performance parameters (e.g., fingerprints) corresponding to the recorded characteristics; and determining corrections to be applied to future processes (e.g. exposure, etch) in the sequence to be performed on the product unit, based on the determined predicted performance parameter.

Abstract: A method including determining a first color pattern and a second color pattern associated with a hot spot of a design layout pattern, the design layout pattern configured for transfer to a substrate, and predicting, by a hardware computer system, whether there would be a defect at the hot spot on the substrate caused by overlay error, based at least in part on a measurement of an overlay error between the first color pattern and the second color pattern.

Abstract: A method to change an etch parameter of a substrate etching process, the method including: making a first measurement of a first metric associated with a structure on a substrate before being etched; making a second measurement of a second metric associated with a structure on a substrate after being etched; and changing the etch parameter based on a difference between the first measurement and the second measurement.

Abstract: A method including: computing a value of a first variable of a pattern of, or for, a substrate processed by a patterning process by combining a fingerprint of the first variable on the substrate and a certain value of the first variable; and determining a value of a second variable of the pattern based at least in part on the computed value of the first variable.

Abstract: A method of defect validation for a device manufacturing process, the method including: obtaining a first image of a pattern processed into an area on a substrate using the device manufacturing process under a first condition; obtaining a metrology image from the area; aligning the metrology image and the first image; and determining from the first image and the metrology image whether the area contains a defect, based on one or more classification criteria.

Abstract: A method includes determining topographic information of a substrate for use in a lithographic imaging system, determining or estimating, based on the topographic information, imaging error information for a plurality of points in an image field of the lithographic imaging system, adapting a design for a patterning device based on the imaging error information. In an embodiment, a plurality of locations for metrology targets is optimized based on imaging error information for a plurality of points in an image field of a lithographic imaging system, wherein the optimizing involves minimizing a cost function that describes the imaging error information. In an embodiment, locations are weighted based on differences in imaging requirements across the image field.
