Abstract:
Methods and systems for automatically generating robust metrology targets which can accommodate a variety of lithography processes and process perturbations. Individual steps of an overall lithography process are modeled into a single process sequence to simulate the physical substrate processing. That process sequence drives the creation of a three-dimensional device geometry as a whole, rather than “building” the device geometry element-by-element.

Claim (Index 19):
A method comprising:\n obtaining design parameters for generating a plurality of metrology targets, each metrology target being of different design and designed for use with a lithography process used to fabricate a physical device on a substrate; designing, by a hardware computer system, a three-dimensional geometrical structure of the metrology targets based on a model of the lithography process and the design parameters for the metrology targets, wherein the model of the lithography process represents a sequence of process steps; perturbing a parameter of a process step within the sequence of process steps; applying the process step with the perturbed parameter to the designed plurality of metrology targets; selecting a subset of metrology targets from the designed plurality of metrology targets based on the application of the process step with the perturbed parameter; performing a computer simulation, by the computer system, of at least one metrology target of the subset of metrology targets; and generating electronic data to enable fabrication of at least one metrology target of the subset of metrology targets for use with the lithography process, where the electronic data, or a derivative thereof, is configured to regulate fabrication of the at least one metrology target of the subset of metrology targets on a substrate.
