Claim 7:
8. A metrology system comprising:
an element handling system for positioning elements for thickness measurements;
a thickness measurement tool comprising at least one 3-dimensional thickness sensor configured to obtain [thickness measurements] a first thickness measurement for a first element and a second thickness measurement for a second element representative of a thickness of the first element and the second element prior to an assembling of the first element with the second element, respectively, and configured to obtain first assembled thickness measurements for an assembled element, wherein the assembled element comprises the first element and the second element,
wherein the at least one 3-dimensional thickness sensor is further configured to obtain a third thickness measurement for a third element and a fourth thickness measurement for a fourth element representative of a thickness of the third element and the fourth element prior to an assembling of the third element with the fourth element, respectively, and is further configured to obtain second assembled thickness measurements for a second assembled element, wherein the second assembled element comprises the third element and the fourth element; and
a computing device coupled to the thickness measurement tool and the 3-dimensional thickness sensor, and wherein the computing device is configured to provide data relating to the difference between the assembled thickness measurements and the sum of the individual first and second thickness measurements, and the data is used to generate a first gap measurement map[s]s,
wherein the computing device is further configured to provide further data relating to the difference between the second assembled thickness measurements and the sum of the individual third and fourth thickness measurements, and the further data is used to generate a second gap measurement map, and
wherein the computing device is further configured to compare the first and second gap measurement maps.
