The quantum efficiency (QE) of photocathodes is key to their being used as electron sources in electron beam lithography and inspection. We have built and are using equipment for measuring quantum efficiency, weight gain, and residual gas pressure. D

Negative electron affinity photocathodes may have useful applications as electron sources for high-throughput microlithography [A. Baum et al., J. Vac. Sci. Technol. B 15, 2707 (1997)]. However, the nature of such a system has raised questions about

This work focuses on two issues crucial to achieving high throughput with a negative electron affinity semiconductor photocathode source. Monte Carlo simulations indicate that for a 50 kV system, as much as 8 μA of current may be delivered to the wa
