Abstract:
A method for measuring thickness variations in a first layer of a semiconductor structure includes: —acquiring an image of at least one zone of the surface of the structure —processing the acquired image so as to determine a map of the thickness variations of the first layer, and comparing the intensity of each pixel of the image with a predetermined calibration curve, the calibration curve being determined for a given thickness of a second layer of the, structure, and —measuring the thickness of the second layer in the at least one zone, —if the measured thickness is different from the thickness of the second layer considered in the calibration curve, and using a correction curve to determine a corrected map of thickness variations of the first layer.

Claim (Index 18):
The method of  claim 1 , wherein the method is implemented on a plurality of semiconductor structures, the quasi-monochromatic light flux having the same wavelength for each structure.
