Electron Beam Microcolumn Technology    

Efficient and precise e-beam direct writing.

Overview

Small e-beam column design to enable multiple column, higher throughput, precise e-beam direct writing.

The technology permits rapid emitter to extractor alignment, which is especially time consuming for miniaturized electron guns.
