SUMMARY

The discussion focuses on calculating the size of an electron beam (e-beam) based on a specified current and pattern size. The user created a 40 square micron pattern using a 5 picoampere (pA) current in approximately 30 seconds. To estimate the e-beam size, it is essential to consider factors such as the current, pattern dimensions, and the specific electron beam lithography system used. Average e-beam sizes typically range from 10 nanometers to several micrometers, depending on the system and settings.

PREREQUISITES
  • Understanding of electron beam lithography principles
  • Familiarity with current measurement in picoamperes
  • Knowledge of patterning techniques in microfabrication
  • Basic concepts of beam optics and resolution
NEXT STEPS
  • Research methods for calculating e-beam size in electron beam lithography
  • Learn about the impact of current settings on e-beam resolution
  • Explore different electron beam lithography systems and their specifications
  • Investigate the relationship between pattern size and e-beam diameter
USEFUL FOR

This discussion is beneficial for students and professionals in fields such as microfabrication, materials science, and semiconductor manufacturing, particularly those involved in electron beam lithography processes.

Homework Statement



Does anyone know a method or calculation, that can calculate the size of an e-beam? I made a 40 square micron pattern, in approximately 30 seconds with 5pA current if this helps... I have no idea how to estimate the size of the beam tho.

or does anyone know the average size of e-beams?
