How we are making the 0.5-NA Berkeley mirco-field exposure tool stable and productive

Abstract

Vibration levels in MET5 exposures were reduced from 1.5 nm RMS to 0.8 nm RMS by tuning the vibration isolation system and removing non-compliant hardware. Frequency doubling exposures were improved by replacing the Fourier synthesis pupil scanner mirror. Focus-exposure-matrix outliers have been solved by patching a bug in the control software. 9 nm half-pitch lines and 8 nm half-pitch lines were printed in 11 nm thick MOx resist.
