Abstract:
A method of applying a measurement correction includes calculating a first correction value based on a first coefficient and the measurement; calculating a second correction value based on a second coefficient, greater than the first coefficient, and the measurement; and calculating a third correction value based on a third coefficient, greater than the second coefficient, and the measurement. The method also includes applying the third correction value to the measurement if a difference between the first correction value and the third correction value is above a first threshold value; applying the second correction value to the measurement if a difference between the first correction value and the second correction value is above a second threshold value; and applying the first correction value to the measurement if the difference between the first correction value and the second correction value is below or equal to the second threshold value.

Claim (Index 37):
A metrology system, comprising:\n a radiation source configured to generate light; a reflector configured to direct the light towards a substrate; an interferometer configured to receive light diffracted from a pattern on the substrate or reflected from the substrate, and to produce output light from the interference between the diffracted or reflected light; a detector configured to receive the output light from the interferometer and to produce a measurement based on the received output light; and a controller configured to determine a correction to the measurement, wherein determining the correction comprises:\n calculating a first correction value based on a first coefficient and the measurement; \n calculating a second correction value based on a second coefficient, greater than the first coefficient, and the measurement; \n calculating a third correction value based on a third coefficient, greater than the second coefficient, and the measurement; \n calculating a first average of measurements based on a fourth coefficient and the measurement; \n calculating a second average of measurements based on the third coefficient and the measurement; \n applying the third correction value to the measurement if a difference between the first correction value and the second average of measurements is above a first threshold value; \n applying the second correction value to the measurement if a difference between the first correction value and the first average of measurements is above a second threshold value; and \n applying the first correction value to the measurement if the difference between the first correction value and the first average of measurements is below or equal to the second threshold value.
