METROLOGY TARGET SIMULATION

A method of simulating an electromagnetic response of a metrology target comprising first and second gratings, wherein the second grating is below the first grating, the method comprising: receiving a model defining (i) the first grating as having a first number of grating lines within a pitch, each...

description	A method of simulating an electromagnetic response of a metrology target comprising first and second gratings, wherein the second grating is below the first grating, the method comprising: receiving a model defining (i) the first grating as having a first number of grating lines within a pitch, each of the first number of grating lines separated by a first pitch; and (ii) the second grating as having a second number of grating lines within the pitch, each of the second number of grating lines separated by a second pitch; using the model and the first pitch to simulate properties of the first grating and generate a first scattering matrix; using the model and the second pitch to simulate properties of the second grating and generate a second scattering matrix; generating a scattering matrix defining properties of the metrology target by combining the first scattering matrix and the second scattering matrix.
