Focused Electron Beam Induced Deposition

Definition

Focused electron beam induced deposition (FEBID) is a nanoscale fabrication technique that utilizes a focused electron beam to induce chemical reactions in a precursor gas, resulting in the deposition of material on a substrate. This process allows for the precise control of material placement at the nanoscale, making it a powerful method for creating complex nanostructures and components in additive manufacturing.
