Abstract:
A method includes measuring a topography of a semiconductor wafer. A distortion function is generated based on the measured topography. Measured alignment data associated with the semiconductor wafer is adjusted using the distortion function. At least one correction factor for an exposure tool is generated based on the adjusted alignment data. The exposure tool is configured based on the at least one correction factor.

Claim (Index 9):
A method, comprising:\n securing a semiconductor wafer in a chuck of an exposure tool; measuring a topography of the semiconductor wafer using an optical level sensor while the semiconductor wafer is secured in the chuck; generating a distortion function based on the measured topography; adjusting an expected alignment mark location associated with the semiconductor wafer using the distortion function to generate an adjusted alignment mark location; measuring alignment data associated with the semiconductor wafer based on the adjusted alignment mark location; adjusting the alignment data using the distortion function; generating a first set of correction factors for the exposure tool based on the adjusted alignment data; configuring the exposure tool based on the first set of correction factors; and exposing the semiconductor wafer in the exposure tool configured with the first set of correction factors.
