Mask-aligner Talbot lithography using a 193 nm CW light source

Wilfried Noell, Toralf Scharf, Raoul Kirner, Andreas Vetter

We present and discuss Talbot mask-aligner lithography, relying on a continuous wave laser emitting at 193nm for the illumination. In this source, a diode laser at 772nm is amplified by a tapered amplifier in master-oscillator power-amplifier configuration ...
