  • Publication number: 20210364929
    Abstract: A method for determining a wavefront parameter of a patterning process. The method includes obtaining a reference performance (e.g., a contour, EPE, CD) of a reference apparatus (e.g., a scanner), a lens model for a patterning apparatus configured to convert a wavefront parameter of a wavefront to actuator movement, and a lens fingerprint of a tuning apparatus (e.g., a to-be-matched scanner). Further, the method involves determining the wavefront parameter (e.g., a wavefront parameter such as tilt, offset, etc.) based on the lens fingerprint of the tuning apparatus, the lens model, and a cost function, wherein the cost function is a difference between the reference performance and a tuning apparatus performance.

  • Publication number: 20210165332
    Abstract: A method involving: obtaining a process model of a patterning process that includes or accounts for an average optical aberration of optical systems of a plurality of apparatuses for use with a patterning process; and applying the process model to determine an adjustment to a parameter of the patterning process to account for the average optical aberration.
