Abstract
BEAMETR technique is developed for robust operator independent measurement of electron beam sizes in two coordinates. This method involves software and a specially designed pattern-sample. In this paper, we report the fabrication of this sample and the demonstration of beam size and shape measurements for different Scanning Electron Microscopes and operating conditions (voltage, aperture, astigmatism) with a good consistency. Electron Beam Lithography system (100 keV) was used for patterning; proximity correction was applied to improve pattern quality. In this chip version, the minimum feature linewidth was 20 nm after lift-off.
