Electron Beam Lithography Systems


Enables 100 times higher throughput for sub-micron fabrications which laser writer cannot do.
The ELS-HS50 contribute to the high-value-added devices like IOT devices which requires high-mix low-volume production.

- Direct writing process from sub-micron to nano meter size (semiconductor laser (DFB), communications (WDM, Silicon photonics), High frequency devices (HEMT), hologram, bio-chip, ASIC, SoC, MEMS sensor devices, power devices)
- Wafer size of nanoimprint mold
- Nanotechnology research and development
