Rooks, Yale University. Alignment Marks. Alignment marks, or “markers” are used to align one layer of lithography with another layer. For example, if you need to print small, thin wires that connect to large, thick pads, then you will need alignment marks so that you can use two separate liftoff steps.. Ziam Ghaznavi.

EBL systems (raster/vector scan, round/shaped beam). Electron Beam Lithography System - ELF 10000 Harvard’s Center for Nanoscale Systems(CNS) will install North America’s first High Speed Elionix ELS-HS50 electron beam lithography system. This will be the third Elionix electron beam lithography system installed into the Harvard CNS cleanroom. Nanoscale fabrication techniques have taken device, systems and material design to a new level. Electron Beam Lithography (EBL) enables the creation of highly accurate nanoscale structures.
