Electron Beam Source Configuration

Electron beam deposition is available in a variety of source and pocket configurations. The choice of chamber geometry, fixturing, number of sources, and pocket configuration strongly depend on the deposition processes and application for which the system has been specified.

For many applications, including lift-off processing, a single e-beam source can be located at the center of the chamber baseplate with the substrates located symmetrically about the material deposition flux at 90 degree angles of incidence. For applications which require co-deposition or specific material isolation, multiple e-beam sources can be located in the same chamber.

Single pocket e-beam configurations are excellent for dedicated processes, preventing any potential for cross-contamination from neighbouring pockets. Using a multi-pocket e-beam carousel allows for many materials to be sequentially deposited from the same source location without having to break vacuum. The size and spacing of the pockets will strongly depend on the typical coating thicknesses and the requirement to minimize cross-contamination between pockets.

Talk to us about it

We’ve found that simply discussing the work and process requirements is the best way to come to a solution. Get in touch!

We look forward to discussing this with you.

This instrument is a workhorse for a number of research groups in Tulane’s School of Science and Engineering.
Please keep up the great work in providing support quickly, professionally, and with strong technical know-how. I’m glad to work with Angstrom.
