Abstract
A method that may include performing first measurements of the height differences between the bumps and the corresponding areas, by illuminating the bumps and the corresponding areas with first radiation; wherein the first measurements are subjected to first measurement errors resulting from a virtual penetration of the first illumination into the layer; wherein each bump has a corresponding area that is proximate to the bump; preforming second measurements of thickness of the layer at the corresponding areas; wherein at least some of the first measurements are executed in parallel to an executing of at least some of the second measurements; determining first measurement errors, based on the second measurements; and determining the height differences between the bumps and the corresponding areas based on the first measurements and the first measurements errors.
