EB Electron Beam Lithography System

Ultra-High Precision Electron Beam Lithography System

ELS-7000

State-of-the-art lithography system. Patterns of 5 nm can be written with the acceleration voltage of 100 kV.

Features

World’s finest pattern writing of 5nm lines.
  • With the maximum acceleration of 100 kV, the electron beam of 1.8 nm diameter provides long-hour-stability. Patterns of 5 nm can be exposed with commercially available resist.
  • The compact configuration of ELS-7000 occupies only small footprint.
   

Acceleration voltage  100kV vs 30kV

5nmLine(40nm Pitch)

   
         
Fine pattern lithography in large area.
  • Beam positioning resolution of 0.31 nm with 18 bit DAC and the laser interferometer with a resolution of 0.6 nm provides 30nm stitching and overlay accuracy. These advantages enable fine pattern lithography in large area.
A variety of shapes are easily exposed.
  • Various pattern elements are available as components to create the pattern on the Elionix-original CAD software provided as standard features.
  • Circle pattern generator for writing circle and arc is available.
  • Variable field size adjustment function, enabling the fabrication of WDM gratings, is available.
