WebJul 1, 2002 · We also studied the non-model-based S_OVL measurement using a 673-nm semiconductor laser with a 10mum x 20mum target size, wafer-to-wafer control of CD and lateral shifts on some critical layers ... WebJan 23, 2024 · An overlay (OVL) shift is measured between the handle wafer and the semiconductor wafer by detecting the plurality of upper alignment marks and the plurality of lower alignment marks. A photolithography process is performed by a photolithography tool to partially form an integrated circuit (IC) structure over the semiconductor wafer.
