The prototype for soft X-ray projection lithography at 13nm wavelength is introduced. It includes a laser plasma source
an ellipsoidal condenser
a transmission mask
the Schwarzschild objective
a wafer and the associated vacuum apparatus. The optical design is optimized to achieve smaller resolution than 0.2μm over a 0.1mm diameter image field of view.
