WebIn this paper, we present a study on the overlay (OVL) shift issue in contact (CT) layer aligned to poly-silicon (short as poly) layer (prior layer) in an advanced technology node [1, 2]. WebThe lateral shift between the layers can be verified with the traditional overlay box. Unlike the traditional BIB target that has micrometer CD size, the CD size of the scatterometry overlay (S_OVL) target is much closer to that on the real device. So, it can much better reflect the overlay (OVL) shift on real devices.
