EB Electron Beam Lithography System

Ultra-High Precision Electron Beam Lithography System

ELS-7800

High precision and stability. The acceleration voltage of 80 kV makes it possible to write ultra-fine patterns of 8 nm.

Features

Ultra-fine patterns. Long hour stability and high throughput.
  • With the maximum acceleration of 80 kV, the electron beam of 2 nm diameter provides long hour stability. Patterns of 8 nm can be exposed with the commercially available resist.
  • The compact configuration of ELS-7000 enables occupies only small foot print.

Example of fine line lithography

Fine pattern lithography in large area.
  • Beam positioning resolution of 0.31 nm with 18 bit DAC and the built-in laser interferometer with a resolution of 0.6 nm provides 30nm stitching and overlay accuracy.
    These advantages make the system appropriate for 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 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.
