Claim 13:
14. A method comprising:
providing inline inspection of a semiconductor assembly comprising:
conveying a first element to a first thickness measurement tool with at least one first 3-dimensional thickness sensor and scanning the first element using the first 3-dimensional thickness sensor to obtain thickness measurements for the first element;
conveying a second element to a second thickness measurement tool with at least one second 3-dimensional thickness sensor and scanning the second element using the second 3-dimensional thickness sensor to obtain thickness measurements for the second element;
conveying an assembled element to a third thickness measurement tool with at least one third 3-dimensional thickness sensor and scanning the assembled element using the third 3-dimensional thickness sensor to obtain a thickness measurement for the assembled element, wherein the assembled element is formed by stacking the first and second elements and a gap is formed between the first and second elements during the stacking.
