Lab 18-2 is a magnetron sputter deposition tool for depositing conductive metallic films.

Announcements

System Overview

Sputter deposition is achieved by bombarding a source material with energetic ions, typically Ar+. Atoms at the surface of the target are knocked loose, and transported to the surface of the substrate, where deposition occurs. Electrically conductive material such as Al, W, and Ti can use a dc power source, in which the target acts as the cathode in a diode system. Sputtering of dielectrics such as silicon dioxide, or aluminum oxide requires an Rf power source to supply energy to the argon atoms.

Supported Processes

Basic "User" access with the Lab 18's provide researchers the ability to load, transfer samples, ans deposit standard characterized materials.. For more details, see Lab 18-2/Processes.

In addition to these, this tool has a number of user-supported recipes for depositing a wide variety of materials. Some of these recipes are documented on [Lab 18-2 User Processes]. If you are curious if your material can be deposited in this tool, please contact the tool engineers via the helpdesk ticket system.
