Lithography alignment
WebMark Design. The JEOL system prefers to see either a cross or an "L"-shaped alignment mark. An example of such a mark is shown here: In this example, the limb width of the … WebIn this case the alignment marks should be designed to minimize this effect, or alternately there should be multiple copies of the alignment marks on the wafer, so there will be alignment marks remaining for other masks to be registered to. Figure 2: Transfer of mask registration feature to substrate during lithography (contact aligner)
