193nm immersion lithography: Status and challenges - SPIE
网页193nm immersion lithography (193i) has been accepted by IC manufacturers as a manufacturing patterning solution at least down to the 45nm half-pitch node. Immersion lithography is a lithography enhancement technique that replaces the usual air gap between the final lens element and the photoresist surface with a liquid medium with a …
IXION 193 SLM - Xiton Photonics
网页The IXION 193 SLM is a single frequency all-solid-state laser system for applications such as optical metrology, calibration of 193 nm stepper optics or bandwidth control of high power ArF excimer lasers. The spectral bandwidth is near its theoretical Fourier limit.
