  • Abstract
    In order to fabricate 0.5 µm rule LSIs, a precision electron beam exposure system, titled EB55, has been developed. A new registration method, that corrects pattern positioning errors derived from wafer warping, was designed for this system, and 0.05 µm stitching accuracy and ±0.1 µm overlay accuracy were attained.
