Abstract
Proximity low energy x-ray lithography using a diamond membrane, in which the wavelength is around 5 nm, is evaluated in order to avoid the difficulties of mask fabrication, inspection, and defect repairs. The resolution is estimated based on a simulation in a SR exposure system optimized considering mask contrast and absorbed power in a resist. The simulated data show that 0.2 micrometers lines and spaces of a 0.1 micrometers tungsten absorber on a 1 micrometers diamond membrane are replicated in a 1 micrometers resist at a mask-to-wafer gap of 10 micrometers.
