In this paper, the effect of resist contrast on the exposure latitude, printing bias, and dark erosion are discussed in the context of proximity x-ray lithography. Positive chemically amplified resists are studied. Both experimental and simulation results show that an exposure latitude of 28% can be obtained for 0.16 micrometers dense lines and a 0.36 micrometers pitch using point source x-ray lithography with a 25 micrometers proximity gap.
