Abstract
A system and method for determining underfill expansion is provided. An embodiment comprises forming cover marks along a top surface of a substrate, attaching a semiconductor substrate to the top surface of the substrate, placing an underfill material between the semiconductor substrate and the substrate, and then using the cover marks to determine the expansion of the underfill over the top surface of the substrate. Additionally, cover marks may also be formed along a top surface of the semiconductor substrate, and the cover marks on both the substrate and the semiconductor substrate may be used together as alignment marks during the alignment of the substrate and the semiconductor substrate.
