Abstract
We report the high-resolution patterning achieved by the laboratory-scale micro-exposure tool for extreme ultraviolet projection lithography realized at the ENEA Frascati Research Center in the frame of a National Project. Such a result obtained using a laser-produced-plasma source, a couple of twin ellipsoidal collectors and a low-cost Schwarzschild-type projection optics shows that it is possible to attain a nanometer-scale spatial resolution using relatively inexpensive projection optics.
