The JEOL JBX-8100FS is an Electron Beam Lithography (EBL) tool.

EBL is a direct-write process that enables patterning on the nanometer scale. Like optical or laser lithography, EBL employs a photoresist-based technique but achieves features one hundred times smaller. This tool is optimized for both high throughput, with high maximum currents and dual current writing modes, and high resolution, utilizing a first in the U.S. 200kV electron beam.

Location: NCFL Room 1004

The JEOL JBX-8100FS is hosted at the NCFL but managed by the Department of Electrical and Computer Engineering.

To access/schedule this tool, contact Eric Carlson (ecarlson@vt.edu), Electron Beam Lithography Manager, Department of Electrical and Computer Engineering.
