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

Announcements

  • Update this with announcements as necessary

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.

Material Restrictions

The Lab 18-2 is designated as a Metals class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email info@lnf.umich.edu for any material requests or questions.


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.

Standard Operating Procedure

Checkout Procedure

  1. Read through the Standard Operating Procedure above.
  2. Complete the training request form [<link> here].
  3. Create a helpdesk ticket requesting training.
  4. A tool engineer will schedule a time for initial training.
  5. Practice with your mentor or another authorized user until you are comfortable with tool operation.
  6. Complete the SOP quiz [<link> here].
  7. Schedule a checkout session with a tool engineer via the helpdesk ticket system. If this checkout is successful, the engineer will authorize you on the tool.
