5 June 1998 ACLV control in x-ray lithography
Author Affiliations +
In this paper, dimensional control of critical features in proximity x-ray lithography is discussed. CD error components attributed to x-ray mask, proximity exposure and resist process are identified. Analysis of linewidth control data at 180 nm and 150 nm ground rules for synchrotron based x-ray proximity lithography is presented. Data have been collected at IBM Advanced Lithography Facility equipped with x-ray stepper built by SVGL and Helios synchrotron radiation x-ray source.
